FACULTY OF ENGINEERING Professor of Environmental Engineering Atlantic LNG Chair in Environmental Engineering Department of Civil Environmental Engineering Tel 868 662 2002 ext. 82503 Cell 868 686 3699 E-mail goutam.banerjeesta.uwi.edu PROF. GOUTAM BANERJEE Major Achievements Prior to joining UWI St. Augustine in September 2013 The research career of Prof. Banerjee started with the landmark bench-scale research study on treatment of coke-oven waste- water by multi-stage rotating biological contactor RBC reactor. The study embarked upon the sequential removal of toxic components contained in coke-oven effluent viz. phenol thiocyanate cyanide and nitrogen with the help of properly acclimatized microbial species in a three-stage RBC reactor. It was revealed that when multiple substances are contained in industrial effluentscross-inhibition takes place amongst differ- ent species of microbes in the presence of multiple toxic substances in single-stage bio-reactors. In order to mitigate these intricate problems in the biodegradation of industrial effluents multi-stage sequential bioreactors are a potential means of treatment. Later down the years Prof. Banerjee was associated as a supervisor with bench-scale and pilot-scale research studies on the purification of turbid pond water for small-scale produc- tion of potable water using a three-stage horizontal roughing filter HRF unit. Following HRF slow-sand filtration improved the quality of water even rendering it potable.This was a major achievement in water supply systems in rural settings where underground water reserves are either scarce andor unfit for drinking purposes due to various contaminants such as arsenic fluoride nitrate TDS and others. In another pilot-scale research project mentored by Professor Banerjee the fluoride contamination problem in groundwater supplies was mitigated by adsorption using water treatment plant sludge containing primarily alum aluminum hydroxide flocs along with settled colloidal solids as well as by suitably processed secondary biomass generated abundantly in wastewater treatment plants both of which are cheap and locally available. The outcome of this study was promising as an economic option for defluoridation using discarded waste products though toxicity imparted post- treatment needs to be addressed by thorough analysis and suitable and cost-effective means of treatment. Subsequently several research works were carried out as supervisor andor in a personal capacity. Amongst these studies i Adsorption of dyes methylene blue MB and rhodamine B RB on suitable processed green pea peels GPP and jowar stalks JS which are abundantly available as agricul- tural residues in developing countries 2 Recycling and reuse of secondary effluent by economic means using different types of filter and adsorbent media 3 Management of arsenic- bearing toxic water treatment plant sludge by means of solidifi- cation and anaerobic digestion 4 Integrated treatment of municipal and industrial wastewaters by aquatic pond system 5 Removal of pesticides from the water environment by activated carbon 6 Removal of fly-ash particles and sulphur dioxide by novel air quality control reactors. Prof. Banerjee was actively associated with several field- based RD projects sponsored by such international agencies as WHO UNICEF WORLD BANK IDRC ICEF Govt. of The Nether- lands as well as various ministries like MNES MUD MRD M. Rly. Govt. of India PHED GOWB GoTr GoOdisha relating to laboratory as well as field level community-based research assignments both in rural and urban settings. These include generation of biogas in anaerobic digestors linked with community latrine using composite waste materials such as night soil market wastes decomposed aquatic weeds gener- ated in post-digestion aquatic ponds supply of potable water through upgrading of traditional surface water sources such as ponds lakes canal etc by horizontal roughing filter and under- situ filter abstraction of groundwater through radial collector well using river-bed filtration technology pollution travel studies from low-cost latrine pits low-cost rain water harvest- ing systems in arid and semi-arid areas solid and hazardous waste treatment by vermiculture appropriate healthcare waste management for developing countries membrane-based desalinationmanagement of leachate from municipal as well as clinical waste land-fills solidification-cum-stabilization and bio-degradation of arsenic-bearing water plant sludge community-based mitigation of arsenic and fluoride-based groundwater contamination introduction and promotion of three-tier water quality surveillance approach for developing nations and many other such projects. He has also been associ- ated with the formulation of essential tools and criteria for model healthy cities. As a consultant Professor Banerjee has been rendering his expertise and consultative support to various government quasi-government and multi-nationalprivate organizations in India and adjoining countries in the areas of water supply and sanitation wastewater management municipal solid waste management systemsEIA and environmental auditing EAand industrial waste treatment and management. The outcome of the above research works of Professor 66
