CSIR-National Environmental Engineering Research Institute (CSIR-NEERI) and SMS Envocare Ltd signed a technology transfer agreement for High Rate Transpiration System (HRTS) to improve waste water management at various industrial clusters in India. SMS Envocare Ltd is involved in the development of environmental infrastructure including common effluent treatment plants (CETPs) and execution of various environmental projects. CSIR-NEERI transferred the know-how as regards HRTS to SMS Envocare Ltd. According to the agreement, CSIR-NEERI will design a HRTS project and SMS Envocare Ltd will execute it for effective waste water management.
SMS Envocare Ltd is engaged in operation and maintenance of CETPs at various industrial clusters. It has been observed that even after primary and secondary treatment of effluent at CETP, treated effluent contains high concentrations of Total Dissolved Solids (TDS), Biochemical Oxygen Demand (BOD), and Chemical Oxygen Demand (COD). High BOD or COD is indicator of presence of the organic content in treated waste water.
Therefore, the treated waste water further needs to be managed in an eco-friendly way. In this context, CSIR-NEERI has found out a promising solution by developing HRTS for zero liquid discharge. HRTS involves the use of dynamic, multi-component soil system as a live filtration device to renovate the waste water through adsorption, ion exchange, precipitation and stabilisation of pollutants through microbial degradation, stated a press release issued by NEERI on Sunday. It is a land application system wherein the waste water is applied in specially designed field layouts with wide ridges and furrows. In ridges, trees having high transpiration capacity are planted, while waste water is allowed to flow through furrows. As the waste water is completely utilised through stomatal network of trees, risk of groundwater contamination is obviated.
Even coloured waste water can also be managed through HRTS. Dr Hemant J Purohit, Chief Scientist and Head, Environmental Biotechnology & Genomics Division, CSIR-NEERI, and Hemant Lodha, Managing Director, SMS Envocare Ltd signed the agreement on behalf of respective organisations. Dr Kishore Malviya, Director, SMS Envocare Ltd; Param Sancheti, Additional Director, SMS Ltd; Dr Amit Bansiwal, Senior Principal Scientist, CSIR-NEERI; Satish Dabe, Principal Scientist, CSIR-NEERI; Karthik R, Senior Scientist, CSIR-NEERI; and Dr Prashant Thawale, Senior Technical Officer, CSIR-NEERI were also present on the occasion.
