Distillery waste which is black in color, very
abnoxious smell wise and has high chemical oxygen
demand(COD) has been cleaned using cemicals and solar
energy. A pilot plant has been set up which can clean
200 liters of diluted distillery waste in two days. The
chemical can be recycled and the waste water has 90%
transmittance and hence is fit for discharge in
waterways. Initial experiments with the pulp paper
effluent has yielded excellent results. NARI can
transfer this technology to
distilleries.
