摘要：
Combination of the waste Fe3+/Cr3+ hydroxide sludge and polymer flocculant used in the treatment of distillery wastewater yielded good results. Fe3 + /Cr3 + hydroxide sludge and polymer flocculants were not effective, when used separately. Various parameters like turbidity, colour, COD, Chloride, Potassium Sodium, Calcium and BOD. Among various polymer flocculants used, anionic polymer RF-440 in combination with Fe3 + /Cr3 + hydroxide sludge gave a maximum removal of turbidity (71%), COD (50%), Chloride (20%), Potassium (48%), Calcium (42%) and BOD (40%).
