Solar detoxification of distillery waste

NARI has developed technology for solar detoxification of distillery waste using photocatalysts. The obnoxious distillery waste is made odorless and completely colorless. The chemical oxygen demand (COD) is also reduced drastically. A pilot plant was set up and ran for 2 years at NARI campus. It could clean 200 liters of diluted distillery waste in two days. The chemical used could be recycled and the waste water had 90% transmittance and hence was fit for discharge in waterways.
