COMPARISION OF PHYSICAL AND CHEMICAL PARAMETERS OF RAW SPENT WASH DISTILLERY WATER BEFOREAND AFTER NANO FILTRATION, WITH THAT OF REVERSE OSMOSIS HUMAN DRINKING WATERV.A. VIJAYA GEETHA, V. ANNAMALAI, V.N. JANAKARAJAN, N. BHUVANESHWARI AND SENTHILKUMARAbstract India is a vast country with many rivers and Tributaries. The Indian people for daily routine living life style habit rely largely on extreme use of water. Water is essential to every Indian house hold needs. Different methods are used to purify water, the methods applied were, Microfiltration (MF) method, Ultrafiltration (UF) method, Nanofiltration (NF) method and Reverse Osmosis (RO) method. In this article we have applied nanomembrane filtration method to purify sugar cane industrial effluents namely Raw Spent wash distillery effluent water diluted with Reverse Osmosis water. The physicochemical parameters were measured before and after Nanomembrane filtration in Raw spent wash distillery, as well as in Reverse osmosis filtered tapwater utilized by people for drinking purpose. There is a 40-70% of Rejection in chemical parameters in Raw spent wash distillery water after Nanomembrane filtration and physical parameter showed greater improvement. But the Rejection in chemical parameter by Reverse osmosis in Ordinary Tap water was found to be more than 85%. The physical parameters showed higher improvement in rejection than Nano filtered Raw spent wash water. |
