Three days training programme on “ADVANCED TREATMENT TECHNOLOGY OF WASTE WATER WITH RESPECT TO RECYCLE/REUSE OF TREATED WATER.” commenced at National Sugar Institute, Kanpur. The programme is being attended by officers of Central & State Pollution Control Boards. The programme has been designed to provide insight of latest processing trends in sugar and alcohol units and advanced waste water treatment technologies to be adopted to minimize fresh water intake and effluent quantity.
In his inaugural address, Shri Narendra Mohan, Director stressed upon the need for making sugar & alcohol units as “Zero Fresh Water Consumption (ZFC)” and “Zero Liquid Discharge (ZLD)” units. National Sugar Institute, Kanpur has worked extensively of working out a business model for the sugar industry and now the standalone sugar units are to be seen as complexes having sugar-alcohol-power generation units.
Because of the availability of significant quantities of water in sugarcane, sugar factories generate lot of surplus water. By adopting advance technologies of “Sulphate Removal System”, “Brine Recovery System”, “Rinse Water System” and “Reverse Osmosis & Ultrafiltration” in combination with existing effluent treatment system, while part of the treated waste water can be reused in sugar and attached distilleries making them as “Zero Fresh Water Consumption (ZFC)” and “Zero Liquid Discharge (ZLD)” units. Molasses based distilleries are already working on “Zero Liquid Discharge” by adopting techniques of Incineration, bio-composting and spray drying of effluent, he said.
Dr. (Mrs.) Seema Paroha, Prof. Biochemistry and Programme Convener made presentation about water management in molasses based distilleries by implementing 4 R’s, i.e. Reduce, Reuse, Recycle and Recover. Shri Anoop Kanaujia, Assistant Professor of Sugar Engineering delivered lecture on “Waste to Energy by Spent Wash Incineration – A Technology”. Spent wash, the effluent from molasses based distillery has reasonably good calorific value and after concentrating it, it can be used as fuel along with other fuels for steam and power generation, he said.
Lectures were also delivered by Shri S.K. Trivedi, Assistant Prof. and Shri Ashok Garg, Assistant Prof. of Sugar Technology on topics related to current scenario of sugar production and on design aspect of Effluent Treatment Plants. Shri Virendra Kumar, Senior Instrumentation Engineer highlighted the role of online monitoring system in maintaining the quality of discharges.
