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.
