Abatement of Pesticide Pollution

"Abatement of Pesticide Pollution: Removal of Organochlorine Pesticide from Water Environment" unlike conventional Environmental Engineering books, centres on the pesticide pollution in water environment and demonstrates a comprehensive methodology for developing a low cost treatment system for the removal of organo-chlorine pesticides with a specific case study on endosulfan removal. It presents the process of adsorbent selection; its characterization and capacity enhancement and explains various process parameters viz. removal rate constants, equilibrium time, and isotherms in a batch environment. It further elucidates the rate limiting step and removal mechanisms. In simulating the field conditions, the possible interference due to the presence of exogenous parameters like various salts, fertilizers and other pesticides are explained. Desorption and regeneration processes of spent sorbent are explained to optimize the utilization rate. The field application of the system is presented by means of detailed fixed bed studies followed by evaluation of a laboratory scale column in terms of bed-volumes of water treated. Finally it explains the process of eluent management employing various methods. With the demonstration of a complete methodology, this book would help researchers in the area of water treatment systems development for rural applications.
