Thermal Cracking of Hydrocarbons: Evaluation of Various Feedstocks Thermal cracking of naphtha, gas-oil, light hydrocarbons such as Ethane, Propane, Butane and their mixtures is an important process for production of Ethylene, Propylene, Butadiene and Aromatics which are basic feedstocks of petrochemical industries. Experiments were carried out in bench scale cracker which allows cracking of different hydrocarbon feedstocks. The report presents evaluation of various feed stocks experimentally and also by SPYRO model simulation. Several runs were carried out in bench-scale cracker unit with different operating conditions that would simulate commercial plant performance with respect to yields. The optimum run conditions for Ethane cracking are: Coil Outlet Temperature (COT) : 810.; Water to Hydrocarbon ratio : 1; Residence time: 0.25s. The optimized process conditions for Naphtha feed are; COT: 810., Ratio: 0.35, Residence time: 0.5 sec. In case of mixed hydrocarbon feed DMDS (Di methyl disulfide) addition was found effective than addition of DEDS (Di ethyl disulfide) as coke formation was reduced by addition of DMDS. For Cyclohexane cracking the yield of 1-3 Butadiene was more compared to other feeds. For Also effect of run length on coke formation was studied using naphtha as feed. Initial coking rate is very high which gradually decreases and then becomes constant. Simulations of different hydrocarbon feed were carried out in SPYRO model to study yield patterns of olefins. 2014
Tailoring Properties of Polybutadiene Rubber based Nanocomposites by using In-Situ and Ex-Situ Approaches Literature shows that BR/Nanocomposites are mostly prepared using solution method or melt compounding method. But the problem with solution process is economically infeasible process also its not environment friendly due to major waste of solvent, while melt intercalation solves them but it gives poor dispersion of nanofillers hence weak interaction between the polymer and nanofillers leading to the objective of the work is to improve the performance of BR nanocomposites through melt compounding method in terms of physico-mechanical properties, thermal properties as well as enhanced dispersion of fillers which can be economically viable and environment friendly process. In ex-situ process of synthesizing nanocomposites reinforcing agents (fillers) used are carbon nanotube (CNT), nanosilica, Cloisite 20A, Cloisite Na+, Combination of Cloisite 20A and Na+. In terms of ex-situ nanocomposites physico-mechanical properties like cut and chip, abrasion, heat build-up are reported here. Also properties of conventional fillers like carbon black and silica were compared with the nanofillers. To overcome the problem of weak intercalation and/or poor dispersion, different types of nanofillers like multiwalled carbon nanotubes and nanosilica are incorporated into the polymer matrix. Effect of nanofillers on kinetics of polymerization is also done, how nanofillers affects the polymerization with fillers is reported here. Along with in-situ polymerization of the fillers their kinetic study, reaction behavior in terms of exothermicity and conversion have been studied and presented here. Also micro structure and thermal properties of the polymer are tested and reported. The BR based nanocomposites were successfully prepared by both in situ and ex situ methods. Effect of nanofiller loading is investigated on the properties of prepared nanocomposites by ex situ melt blending. The nanocomposites were also compared with conventional composites. The in situ nanocomposites where tried to be synthesized with the filler, which showed best overall properties in in situ nanocomposites. Furthermore, the reaction condition parameters are well optimized in the in situ process. The intricate analysis and subsequent discussion on the experimental finding leads to the following conclusions: The characterization of nanofillers were carried out by using powder X-ray diffraction (XRD), and BET-surface area measurements. Surface area of all nanofillers are higher than the conventional fillers. Nanofillers import considerable enhancement in physico-mechanical properties of BR/NC's. For example, in the ex situ process, the BR nanocomposites containing 7 phr loaded Cloisite 20A showed 215% and 230% improvement in tensile strength and %EB respectively, also 42% in hardness as compared to the matrix devoid of nanomaterial. Nanocomposites show better properties at lower filler loading than the conventional composites with carbon black and silica. Thus, much lighter rubber product November 2014
Guard Bed Materials Development for Impurities Removal from Petroleum Feed Stock Crude oil consist of impurities such as nitrogen, sulphur, metals, silicon etc. Nitrogen, sulphur and metals removal process are very deeply explore. Apart from above stated impurities halide and acid containing compounds causes corrosion problem in the pipe lines, reactors which contributes to catalyst deactivation. Corrosion is prevented by using phosphorus containing corrosion inhibitors. These chemicals form thin layer in between stream and metallurgy. During downstream processes of such streams can cause problem related to catalyst deactivation, lumping and pressure drop. Due to these reasons phosphorus removal from stream has become a research topic in recent year. Adsorbents are used for removal of impurities from hydrocarbon stream. There are mainly three adsorbents to remove phosphorus i.e., alumina, bentonite clay and magnesium silicate. Current research work will be on the synthesis, modification, characterization and evaluation of above adsorbents for phosphorus and other metal impurities. On the basis of literature survey, mainly four adsorbents were used for removal of phosphorus from petroleum feedstock. The adsorbents were characterized by X-Ray diffraction to identify the crystal structure and phases, BET surface area to find out the physical properties of adsorbents and Temperature Programme Desorption to know the strong and weak active sites. The adsorbents were evaluated through batch reactor and continuous reactor for adsorption process between adsorbents and petroleum feedstock (kerosene). Analysis of adsorbents were done by Fourier Transform Infra-Red to find out the quantity of phosphorus in liquid products and in feed, Induced Coupled Plasma was used to know the exact concentration of phosphorus in feed and on adsorbents, Nuclear Magnetic Resonance was used to identify the chemical shift of compounds and to identify the adsorption type (physical and chemical) on the adsorbents. The results of Fourier Transform Infra-Red, Induced Coupled Plasma and Nuclear Magnetic Resonance shows that the iron alumina and magnesium silicate adsorbents are the promising candidates for the removal of phosphorus from petroleum feedstock. Induced Coupled Plasma gave ~98% of phosphorus removal from feed and the adsorption capacity for trapping of phosphorus on iron alumina is 18% and magnesium silicate is 11%. The parametric studies was done through various parameters such as temperature, concentration and different adsorbents. The adsorbents studies were completed by using batch reactions, continuous reactions, adsorbent capacity and recycle data. The scope of this thesis is to understand the effect of adsorbents for phosphorus removal. 2014
Polybutadiene rubber nanocomposites In the present study, elastomer nanocomposites based on polybutadiene rubber and dierent kind of nanollers were prepared either by using in situ or ex situ methods. The eects of dierent nanoller and their compounding on the physico-mechanical and thermal properties of BR nanocomposites were investigated. Nanollers like nanosilica, sepiolite, pangel, hydrotalcite, montmorillonite, and CNT were used as reinforcing agent. The textural properties of the nanomaterials were characterized by powder X-ray diraction ( XRD), and BET-surface area measurements. The mechanical properties of various nanocomposites prepared by ex situ method were compared with composites made of conventional llers such as carbon black and silica. The result indicates that composites prepared from nanollers show higher mechanical properties as compared to conventionally lled composites. It is also observed that the performance of nanosilica in BR matrix enhanced in presence of silane as a coupling agent. The composite containing 3 phr loaded Cloisite 20A showed 245% improvement in tensile strength compared to the matrix devoid of nanomaterial. Also the composite containing 5 phr loaded CNT showed 137% improvement in tensile strength. Thermal analysis of the nanocomposites and gum BR vulcanizates itself was done by thermogravimetric analyzer. It showed that the addition of nanoller increses the thermal stability of the nanocomposites. This may be due to the heat shielding eect of the incorporated nanollers in the polymer matrix. The eect of best nanollers, obtained from ex situ method such as CNT and nanosilicasilane at minimum ller concentration, on the mechanical properties of BR nanocomposites is further studied via in situ process. A maximum of 72 % improvement in tensile strength is accomplished using 1 phr nanosilica loaded BR nanocomposites as compared to gum BR vulcanizate. The swelling and thermo gravimetric analysis results of all the BR based nanocomposites are in good agreement with mechanical properties of the same. 2013
Biodiesel production under part microwave synthesis In this project work a novel technique “Microwave Synthesis” for production of Biodiesel is used. In microwave, heating takes place based on the selective absorption of microwave irradiations by the polar molecules whereas non-polar molecules are inert to them. Experimental work is carried out and discussed extensively for jatropha oil feedstock. This technique offers a trouble-free and fast route for the production of Biodiesel. In this research project different procedures to produce Biodiesel are followed such as Inside microwave where the entire reaction mixture is exposed to microwave radiations, the second procedure where a part of methanol was added first and then the later one, third procedure with heterogeneous catalysts using same procedure as second and last was about doing the production without catalyst. The conversions obtained by the above methods are 84.85%, 94.27%, 96.43%, 86.48%, 90.55% respectively. June 2013
Process Design for Advanced Biological Treatment of Petrochemical Wastewater etrochemical industry produces a wide variety of chemicals, which include both organic and inorganic compounds. Petrochemical plants generate wastewater containing various conventional pollutants as well as specific petrochemical constituents like aromatics, phenolics, cyanides, sulphides, fluorides, halogenated compounds, polycyclic hydrocarbons and detergents etc., many of which are potentially toxic and carcinogenic besides being explosive and corrosive. Since the project will be on advance biological treatment of wastewater having high COD and turbidity from a specific polymer stream of plant, initially analytical studies on determination on Polyvinly alcohol (PVA) and Nonyl phenol (NP) was undergone. Later, enrichment of already available acclimatized cultures capable of degrading PVA & NP was carried out & and a Submerged Aerated Biofilter Column (SAB) was set up. Two columns were set up one with mixed culture S1, S2, S3, S4, S5 & S7 and another with mixed culture S2 & S7 (from shake flask study it showed better degradation). Synthetic water containing PVA 200 ppm, 100 ppm, NP 30 ppm, was treated at air flowrates of 100 and 200 mL/min and Water flowrates of 0.8 and 1.6 mL/min. The results indicate that with synthetic wastewater optimum conditions are pH 6.5-8.5 , DO approx 6.5, Water flowrate 0.8 mL/min for COD ranging 250-500 ppm, PVA concentration = 200 ppm, NP concentration 30 ppm and Air flowrate 100 mL/min (No change at higher flowrate). Based on the results obtained with synthetic wastewater, a petrochemical (polymer manufacturing) wastewater stream having significant concentrations of COD (250 ppm), Turbidity (200-250 NTU), PVA (<30 ppm) and NP (4 ppm) was taken for SAF study. Its Conductivity was 150-160 uS, DO 6.5 and pH 6.5-8.5. The Total Solids was 250-350 ppm, TSS, 60-70 ppm and TDS, 200-300 ppm. Experiments were carried out at different flowrates (0.8 mL/min, 1.2 mL/min and 1.6 mL/min).Best result was obtained at 1.2 mL/min flowrate and in column having mixed culture S1, S2, S3, S4, S6 & S7 which shows COD 82%, Turbidity 87%, PVA 88%, NP 88% reduction. And column is running continuously since 8 months. Initial and final colony characteristics of microbial cultures were studied and microbial loading was calculated. Mechanical integrity & strength of used GAC, even after 8 months of study, have not changed much from fresh GAC. Design of the reactor was calculated for the petrochemical wastewater stream studied. Further study was performed with 40% petrochemical wastewater stream having color and 60% petrochemical wastewater stream having PVA and NP which I have used in this experiment. But clogging was occurring in the SAF columns. Hence another treatment must be added prior to SAF to avoid clogging and to get effective reduction in COD and Turbidity. Wastewater having color can be removed preliminary by Fenton oxidation experiments and carried by GAC adsorption and biofilteration. 2013
Paraffin isomerization using zeolytic materials Hydroisomerization of n-paraffin is an important reaction in oil refining processes due to environmental considerations and it is integral part of refining processes for improving the quality of fuels and lube oils. Subsequently, hydroisomerization of n-paraffins had seen significant improvements both in terms of catalyst design and processes. Hydroisomerization of long chain paraffins to iso-paraffins, to obtain product with excellent cold flow properties and superior yields, had depicted an immense growth owing to the emergent demand for high quality fuel oils for automobile and industrial applications. Hydroisomerization for conventional diesel dewaxing and renewable diesel dewaxing had boosted the yields of diesel fuels to meet the ever rising demand. Isomerization reactions generally take place over bifunctional metal/acid catalysts. An ideal catalyst would be the one which provide a high yield of isomerization and should have shape-selectivity to react only with n-paraffins. To achieve these characteristics, the catalyst should have suitable compositional and structural characteristics, mainly: proper balance between metal and acid sites, medium pore size, high dispersion of metal on surface of catalyst, mild acidity, and strength distribution of acid sites. The scope of this thesis was to understand the effect of various zeolites with respect to Si/Al ratio, pore size and pore dimension on hydroisomerization of n-decane. In this study, Beta zeolite, Silica -alumina and ZSM-5 zeolite based materials were chosen for acid function and shaped into extrudate by adding Alumina as binder. The shaped extrudate were ion-exchanged with platinum using platinum tetraamine II chloride. The catalysts were characterized by XRD, SEM, BET surface area, and ammonia TPD methods. And the catalysts were evaluated in batch reactor using n-decane as a model compound for hydroisomerization reaction. Pt-Silica-Alumina showed low conversion and high selectivity compared to other zeolites. High performance of above catalysts might be due to low acidity, proper distribution of platinum across the mattix and necessary pore average diameter which facilitates ready diffusion of reactants. 2013
Metal-organic frameworks : A new class of hybrid materials for catalytic application. Metal-organic frameworks (MOFs) are crystalline hybrid materials with interesting chemical and physical properties. This thesis is focused on the synthesis and characterization of dierent MOFs and their applications in heterogeneous catalysis. Metal-organic framework forms a 2-D or 3-D structure with high surface area by connecting metal with ligand and sometimes secondary building blocks. MOFs have got advantages over existing porous materials and zeolite. They have got potential application for separation,gas storage (H2,CH4,N2) storage,sensors,drug delivery,catalysis etc. There is wide scope for MOFs as heterogeneous catalyst since very few studies have reported on catalytic application of MOF. As an explorative study synthesis of various MOFs using dierent metal precursor and ligand have done based on solvotheraml method except for RMOF-3. 1,4- benzenedicarboxylic acid ligand based ve (RMOF-1,RMOF-2,RMOF-5,RMOF-6,RMOF- 11),and 1,3,5-benzenetricarboxylic acid based three( RMOF-3,RMOF-7,RMOF-10)MOFs were synthesized. RMOF-3 was synthesized by crystallization method. Various characterization techniques were applied to study the properties of these MOFs. Xray powder diraction (PXRD), BET surface area, dierential scanning calorimetry analysis(DSC) and thermogravimetric analysis (TGA) were extensively used. Catalytic studies using MOF materials,as heterogeneous catalysts in organic transformation reactions were performed. Among the eight MOFs were synthesized, four shows catalytic activity (RMOF-1,RMOF-2,RMOF-6,RMOF-7). RMOF- 2 and RMOF-7 showed good result for alkylation,acylation reactions.Initial studies on alkylation , acylation reactions were carried out using these MOFs. June 2012
Safety Integrity Level of a chemical industry for safer operations using LOPA methodology Safety Integrity Level (SIL) is a criterion that judges the reliability of the safeguards. It species or assigns the required safety integrity level to the scenario to identify the level of risk involved in the scenario. International Electro technical Commission (IEC) 61511 has published dierent methods for the determination of SIL in chemical process industries. These methods are categorized based on their approach to determine SIL. Of the three dierent approaches, qualitative, semiquantitative and quantitative, the most commonly used methods for SIL determination are Risk graph and LOPA (Layer Of Protection Analysis) method. Both methods distinctively calculate the required safety integrity level for the given scenario. LOPA, Layer of Protection Analysis, is a simplied semi-quantitative risk assessment method used to evaluate the risk of selected accident scenario. The purpose of LOPA is to develop on the information prepared during a qualitative hazard evaluation technique such as HAZOP (Hazard and Operability Study) or PHA (Process Hazard Analysis) to nally identify the Safety Integrity Level (SIL) in an industry. Depending upon the complexity and consequence severity involved in the process, dierent safeguards or line of defenses are provided in an industry. These safeguards however may or may not be able to act independently during the time of event and thereby fail to act as an independent protection layer in an industry. LOPA, in this way, provides a method to test the independence of different layers in an industry and rank their ability to protect the industry from an event by assigning a Safety Integrity Level. Carbon black manufacturing facility with its application in rubber and tyre industry shows the results of LOPA method. Safeguards/ independent protection layers upon analysis are added to strengthen or continue to keep the industry intact from any dangers. The method proves vital in concluding whether the industry has sucient layers provided. However, it has two negative points such as LOPA method fails to identify which layers are needed to protect the plant and the results obtained from analysis are dependent on the corporate criteria. Change in this criteria can signicantly alter the results obtained from LOPA analysis. June 2012
Production of Synthesis gas by Carbondioxide Reforming using Perovskite Catalysts Recently the development of CO2 reforming of methane (Dry reforming) has been investigated to produce syngas. Even though steam reforming of methane is widely industrialized to produce syngas (a mixture of H2 and CO), lower ratios are needed for oxo- and Fischer–Tropsch synthesis. Carbon dioxide reforming of methane offers advantages such as the production of syngas with a lower H2 /CO ratio and it obviates a water vaporization step to produce steam, an energy consumer process, and eliminate CH4 and CO2 two major greenhouse gases. However, the process has not found wide industrial application due to severe catalyst deactivation, basically caused by carbon formation. Therefore, it is of great interest to develop stable catalysts without severe deactivation. In the present study work dvelopment of perovskites to achieve stable operation for CO2 reforming of CH4 was carried out. The use of precursors such as perovskite like oxides ABO3, in which A-site cation is a rare earth and/or alkaline earth and B-site cation is a transition metal has increased recently for methane reforming. Perovskites not only fulfill the stability requirements for these reactions, but also by further reduction of B-site cations which remain distributed in the structure, they form well dispersed and stable metal particle catalysts June 2011
Catalytic conversion of Methane and CO2 to Synthesis Gas Consuming two major greenhouse gases, carbon dioxide (CO2) and methane (CH4), to produce synthesis gas, which is a mixture of carbon monoxide (CO) and hydrogen (H2), carbon dioxide reforming of methane shows significant environmental and economic benefits. Recently the development of CO2 reforming of methane (Dry reforming) has been investigated to produce syngas. Even though steam reforming of methane is widely industrialized to produce syngas (a mixture of H2 and CO), lower ratios are needed for oxo- and Fischer–Tropsch synthesis. Carbon dioxide reforming of methane offers advantages such as the production of syngas with a lower H2 /CO ratio and it obviates a water vaporization step to produce steam, an energy consumer process, and eliminate CH4 and CO2, two major greenhouse gases. However, the process has not found wide industrial application due to severe catalyst deactivation, basically caused by carbon formation. Therefore, it is of great interest to develop stable catalysts without severe deactivation. This work is mainly focused on the development of base metal like nickel-based catalysts to achieve stable operation for CO2 reforming of CH4. The Nickel (Ni)- catalyst prepared by impregnation method using support g-Al2O3 and different types of promoters (CeO2,ZrO2, K2O and MgO) to improve activity, stability and selectivity in order to reduce coke formation and to achieve long-term operation. Nickel catalysts promoted by the CeO2 shows higher dispersion of the metal particle on the surface of the support than the unpromoted catalysts. It has been found that the ZrO2,CeO2, K2O and MgO promoted 10%Ni/g-Al2O3catalysts shows good activity, stability and long-term operation as compared to the unpromoted catalysts. It reduces the deactivation rate.The catalysts were characterized by the Xray Diffraction Method and BET Method suggests types and nature of crystalline phases present, degree of crystallinity, amount of amorphous content, orientation of crystallites, BET Surface Area ,Pore Volume , Pore Diameter over different Catalysts.

Preparation of catalyst for synthesis gas production Consuming two major greenhouse gases, carbon dioxide (CO2) and methane (CH4), to produce synthesis gas, which is a mixture of carbon monoxide (CO) and hydrogen (H2), CO2 reforming of CH4 shows significant environmental and economic benefits. However, the process has not found wide industrial application due to severe catalyst deactivation, basically caused by carbon formation. Therefore, it is of great interest to develop stable catalysts without severe deactivation. This work is primarily focused on the development of base nickel-based catalysts to achieve stable operation for CO2 reforming of CH4. Dry reforming reaction involves reaction between methane, major component of natural gas, and carbon dioxide to produce syngas. Important feed stock to chemical and petrochemical industries to produce many kinds of chemical such as methanol, ammonia is derived from syngas. It also source for hydrogen that can be used directly or in a fuel cell. About 50% of all hydrogen is produced from natural gas. Furthermore, the dry reforming reaction has an environmental benefit where it consumes CO2 and methane which are classified as green house gases that cause global warming. This project work presents an experimental investigation for dry reforming reaction using Nickel (5 and 10 % loading) based supported catalyst prepared by impregnation method. Supports and promoter (?-Al2O3 and ZrO2, CeO2, La2O3) and calcination temperatures of the range from 500 to 650°C were used. The prepared catalysts were tested in Fixed bed reactor under atmospheric pressure, 600 ml/min flow rate and at 600, 650 and 750 °C temperatures. 10%Ni/5% ZrO2 -?-Al2O3 and 10%Ni/5% CeO2-?-Al2O3 catalyst shows higher conversion of methane(CH4) is 84% and 80% at higher Temp 700oC and 730oC respectively .It shows good activity, stability and lower deactivation rate than the other catalysts. The addition of promoters improved the stability of catalyst in terms of coke inhibition by enhancing the dissociation of oxygen intermediates. In fact higher CH4, CO2 Conversion and hydrogen yield were obtained with this Catalyst. The present work deals with the catalysts prepared by the impregnation method and their characterizations (Atomic Absorption spectroscopy, X-ray Diffraction and Scanning Electron Microscopy). The atomic absorption spectroscopy shows the less % of Nickel loading on the support. In future, the percentage of Nickel loading can be maximizing by minimizing filtration loses. The catalysts can be prepared by using different types of preparation techniques (Sol-gel, Precipitation and Co-precipitation Methods) and different types of support or promoters (K, MnO, and MgO) can be used to inhibit the coke formation. The activity performance and characterization (BET, TPR and TPO) of the catalyst can be done. And catalysts can also be prepared by changing the parameters of pretreatment method involves in impregnation method such as Calcination temperatures, Reduction temperatures and activit 2010
Chromium removal by electrocoagulation Electrocoagulation is an effective process for the destabilization of finely dispersed particles by removing hydrocarbons, greases, suspended solids, and heavy metals from different types of waste water. People have long been trying to find a cost effective and reliable way to treat waste water and electrocoagulation is one of this ways to treat waste water. Using electrocoagulation to remove hexavalent chromium involves reducing hexavalent chromium to its insoluble trivalent form and precipitating it as a hydroxide or oxy hydroxide. Synthetic solutions of varying chromium concentrations (5-20-50 ppm) were prepared. Results obtained with synthetic wastewater in batch process revealed that the most effective removal capacities of the studied metals could be achieved when the pH was kept at 3, initial concentration 20 ppm, time taken 30 min and voltage at 13V. In addition, the increases of electrical potential in the range of 3-13 V. Batch and Continuous study were carried out at laboratory scale. Laboratory Scale experiments were conducted for different pH range for different electrode configuration and different flow rate. Electrocoagulation was able to bring down chromium concentration Efficiency was achieved up to 94%. Removal efficiency of chromium with Aluminum electrodes is lower than Iron electrode. The energy consumption is lower with Iron electrode, while the electrode consumption is lower with Aluminum electrode. Electrocoagulation particularly viable is that it is three times cheaper than other purification method. Also, it can be conclude that the electrocoagulation process has the potential to be utilized for cost – effective removal of heavy metals from water and wastewater. The results suggest that electrocoagulation can be used effectively for the removal of Cr (VI). June 2008
Removal of Fluoride from drinking water by Electrosorption Fluoride in drinking water is known for both beneficial and detrimental effects on health. Contamination of drinking water due to fluoride is a severe health hazard problem in many parts of the world. Fluorosis a disease caused by ingestion of fluoride in excess through water, food, and air is a serious health problem. According to UNESCO (status January 2007) more than 200 million people worldwide rely on Drinking Water with fluoride concentrations higher than the present WHO guideline value. More than 20 developed and developing nations endemic for fluorosis. In India, first detected in Nellore district of A.P. in 1937. Water with Required Amount of Fluoride: 0.6 mg/litre to 1.5 mg/litre. The detrimental effects of excessive fluoride can be controlled by defluoridation of natural waters. A number of methods of defluoridation are available; however not all the methods are suitable for all circumstances and hence proper justification is required for selection an appropriate method for a given situation. Certain under-exploited but abundantly available materials like activated alumina have indicated excellent potential for fluoride uptake. Electrosorption (adsorption + electric potential) seems to be promising for the effective removal of fluoride. The main objective of study is to develop the efficient fluoride removal technique based on Electrosorption using activated alumina. Electrosorption technique has shown the enhanced fluoride removal efficiency compared to that with conventional adsorption. The optimization of the process was achieved under various experimental parameters like Fluoride concentration, electric potential, volumetric flow rate, and pH for both batch and continuous operation mode. The comparison of the performance of the Electrosorption system proved to be more efficient than conventional alumina process in removing fluoride from water. The enhanced efficiency with Electrosorption system was due to simultaneous regeneration of activated alumina. Therefore Electrosorption process coupled with adsorption of fluoride on activated alumina column can be used effectively for the fluoride removal from drinking water. June 2007
Removal of arsenic from drinking water by Electrocoagulation. Arsenic occurs naturally in the environment and as a by-product of some agricultural and industrial activities. It can enter drinking water through the ground or as runoff into surface water sources. Since human exposure to arsenic creates severe short- and long term health effects, different physico-chemical techniques have been employed around the world for its removal. In the present study Electrocoagulation (EC) has been evaluated as a treatment technology for arsenite [As (III)] and arsenate [As (V)] removal from water. Laboratory scale experiments were conducted with three electrode materials namely, iron, aluminum and Stainless Steel to assess their efficiency. Arsenic removal obtained was highest with iron electrodes. EC was able to bring down aqueous phase arsenic concentration to less than 10 ppm with iron electrodes. Current density was varied from 0.65 to 1.53 mA cm-2 and it was observed that higher current density achieved rapid arsenic removal. Experimental results at different current densities indicated that arsenic removal was normalized with respect to total charge passed and therefore charge density has been used to compare the results. Effect of pH on arsenic removal was not significant in the pH range 6-8. Arsenic removal efficiency achieved up to 98 percents. June 2007
