EFFECTIVE TREATMENT OF SPENT WASH DILUTED WITH SUGAR EFFLUENT BY USING CHEMICAL AGENTS

摘要

The paper deals with the removal of colour, odour, TDS and COD from the spent wash using chemical agents such as calcium oxide and hydrogen peroxide. Odour has been completely removed from the diluted 10% spent wash when treated with calcium oxide and hydrogen peroxide. Three different treatments were performed with calcium oxide, hydrogen peroxide and both these in combination. Treatment with combination of the two chemicals has shown highest removal of colour (95%), TDS (54.5%) and COD (63.7%) from the diluted spent wash.
