Security risks arising out of these threats are real and must be assessed to determine whether the security measures employed within the facility are adequate or need enhancement. The essential components of security management programme include security risk assessment, security countermeasures, and emergency response. Security risk assessment can be carried out qualitatively by threat analysis, vulnerability analysis and developing Security Risk Factor Table. Threat analysis involves identifying types and sources of threats, and their likelihood; knowing adversaries, their intentions and capabilities. Vulnerability analysis identifies the weaknesses in a system that adversaries can exploit. Terrorists exploit the vulnerabilities to inflict maximum damage. | Source/Dept | M.Tech theses@IITK/CHE | | | | Title | Security Risk Assessment Of Chemical Process Industries From Intentional Threats | Scholar

Kaistha, Nitin | Abstract | The Chemical Process Industry forms a vital and large part of the economy of any country. It provides crucial support to transport, manufacturing and energy sectors, produces valuable exports and provides huge employment. Chemical process industries such as oil refineries, fertilizer plants, petrochemical plants, etc., which handle hazardous chemicals, are potential targets for deliberate actions by terrorists, criminals and disgruntled employees. Security risks arising out of these threats are real and must be assessed to determine whether the security measures employed within and around the facility are adequate or need enhancement. The essential components of security management programme include security risk assessment, security countermeasures, and emergency response. Threat analysis involves identifying types and sources of threats, and their likelihood; knowing adversaries, their intentions and capabilities. | | Source/Dept | M.Tech theses@IITK/CHE |
Sugar | | | | | Title | Enhancement Of Granulation In Usab Reactor By Natural Polymer Additives | Scholar | Tiwari, Manoj Kumar | Supervisor | Guha, Saumyen | Abstract | One of problems of treating low strength wastewater in upflow anaerobic sludge blanket (UASB) reactors is the inability to generate and/or maintain a high level of granulation in the reactor. As a result, the reactors are highly susceptible to hydraulic and organic shock loadings often encountered in domestic sewage treatment. Treatment of a low strength synthetic wastewater (COD 750-850 mg/L) containing sucrose was studied in lab-scale UASB reactors operating under identical conditions to examine the effects of periodic additions of natural polymer additives. The organic loading rate was 1.75 ± 0.074 Kg COD/m2/day. The additives in five reactors were as follows: control with no additive, bulk Reetha extract, cationic part of Reetha extract, anionic part of Reetha extract and Chitosan. The whole experimental period of 254 days were divided into four segments: start-up period and steady states I, II and III. No effect of polymer additions was observed on COD removal efficiency, | Source/Dept | http://172.28.64.70:8080/dspace/handle/123456789/122 | | | | Title | Biological Treatment Of Effluent From Brewery Industry Followed By Reverse Osmosis | Scholar | Sharma, Ramesh Narayan | Supervisor | Bhattacharya, P K | Abstract | Brewery liquor was treated biologically using zymomonus mobilis as strain for conversion of sugar into yeast. A reduction of 96% in the amount of total reducing sugars (TRS) and about 76% reduction in COD was achieved in the biological treatment step. A shifting order type rate equation where the order shifts from zero at high concentration to n at low concentration was found to predict the TRS reduction with high accuracy. Ultra -centrifuge was used to separate out the yeast formed during the biological tr eatment. Yeast separation was found to be complete beyond a speed of 10,000 rpm. The clarified biologically treated liquor was subjected to reverse osmosis (RO) (using HR95PP membrane) for removal of all the remaining solutes and thereby producing an effluent that can be disposed/reused. Permeate flux during RO was predicted using osmotic pressure model. The values for osmotic pressure of Brewery liquor’s solute constituents were estimated through modified osmotic pressure and co. | Source/Dept | http://172.28.64.70:8080/dspace/handle/123456789/10 | | | | Title | Studies On The Ultrafiltration Of Clarified Limed Sugarcane Juice For The Recovery Of Sugar Using Stirred Cell: Flux And Retention Analysis | Scholar | Sarode, Abhay Dadarao | Supervisor | Bhattacharya, P K | Abstract | Ultra filtration Process Was Applied To Separate Sugar From Sugarcane Juice.

Barthwal, R R | Abstract | During the past few decades Indian industries have registered a quantum jump, which has contributed to high economic growth but simultaneously it has also given rise to severe environmental pollution. Consequently, ambient air and water quality is seriously affected which is far lower in comparison to the international standards. The problem is worse in the case of water pollution. It is found that one-third of the total water pollution comes in the form of effluent discharge, solid wastes and other hazardous wastes. Untreated or allegedly treated effluents have increase the level of toxins in like cyanide and chromium up to 20 times the safe level in 22 critically polluted areas of the country. The surface water is the main source of industries for waste disposal. It is found that almost all rivers are polluted in most of the stretches by some industry or the other. | Source/Dept | Ph.D thesis @IITDelhi/HSS | | | | Title | Biological Treatment Of Prehydrolysis Liquor (A Pulp Mill Effluent) Followed By Membrane Separations | Scholar | Fating, Jitendra S. | Supervisor | Bhattacharya, P K | Abstract | Treatment of prehydrolysis liquor (phl) was done biologically using sacchromyces cerevisiae and zymomonas mobilis as strain which converts sugar into yeast. Reduction in total reducing sugar (trs) was 65% and for cod it was 62%, using saccharomyces cerevisiae; whereas, reduction in trs was 79% and for cod it was 72%, using zymomonas mobilis. Reduction in brix values were obtained 44% and 56% for s.cerevisiae and zymomonas mobilis, respectively. Modeling was done to predict the rate equation in both the cases and the reaction order in case of s.cerevisiae was obtained to be 2.6 and for the case of zymomonas mobilis it was found to be 3.5. Ultra-centrifuge was used to separate out the yeast formed during the biological treatment. Yeast separation was observed to be complete beyond a speed of 10,000 rpm.

Tare, Vinod | Abstract | This research was a part of an ongoing larger study dealing with improvements in the degree of treatment some typical industrial effluents viz. Distillery pulp and paper tannery etc. so as to meat the regulatory standards particularly in terms of colour and COD removal. Ozonation as a pre - or post - treatment to make the colour and chemical oxygen demand (COD) causing substances in the effluents assailable to bi ological systems assign to wastewater treatment plants has been considered a promising option. This research forced on developing some of the compounds most commonly found in industrial effluents of concern. The two model compounds chosen were tannin and lignin. As a first step attempt was made to investigate the effect of ozonation on certain physical chemical and biochemical properties of tannin and lignin. | Source/Dept | M.Tech Theses@IITK/EEMP | | | | Title | Energy Efficiency And Technical Efficiency Of Indian Pulp And Paper Industry | Scholar | Vinay, Gupta | Supervisor | Singh, Anoop | Abstract | Improving energy efficiency is crucial for cost competitiveness of firms, for managing energy demand and utilisation of scarce resources of a country, and to reduce adverse environmental impact of energy use. This thesis analyses energy efficiency in Indian Pulp & Paper Industry using plant-level data for the period 1992-2002. Inter-plant comparison of specific electricity consumption and specific fuel consumption reveals significant differences across these plants. An econometric analysis is done to identify factors that influence energy efficiency in these plants. Further, application of Data Envelopment Analysis (DEA) is applied to rank the plants according to their technical efficiency and to identify the possibilities of improvement in input factors. It has been found in the econometric analysis that specific electricity consumption depends on plant capacity, capacity utilization, input mix, technology of the pulping process and paper quality. | Source/Dept | M.Tech Theses@IITK/IME | | | | Title | Enhancement Of Biodegradability Of Some Model Refractory Compounds By Ozonation | Scholar | Devendra, Prakash Saroj | Supervisor | Tare, Vinod
Bose, Purnendu | Abstract | The presence of non-biodegradable or refractory organic matter in wastewaters from many agro-based industries, e.g., pulp and paper, distillery, tannery, etc., renders the treatment of such wastewaters by aerobic/anaerobic biodegradation processes difficult. The refractory component in such wastewaters consists of either hydrolysable or condensed 'poly-phenolic' macro molecules of plant origin, i.e., tannin, lignin and products derived from these substances. Use of ozonation in conjunction with biodegradation appears promising for treatment of such wastewaters, due to the propensity of ozone to attack aromatic rings and double bonds in organic molecules, the very structures that are responsible for the color and refractory nature of such compounds. The main objective of this study was to investigate the extent of mineralization of total organic carbon (TOC), as represented by decrease in chemical oxygen demand (COD) for refractory model compounds of natural origin. | Source/Dept | M.Tech Thesis@IITK/EEMP |
