Abstract (AB)	Sugar factory wastewaters consist mainly of non-toxic substances namely, dissolved sugar, fine bagasse particles, smut, furnace ash and oil/grease. Seventy-five mg/L COD appears to be an achievable target during week day crushing, if pollution reduction at source is practised to reduce the hydraulic, BOD, COD and solids loading. Biochemical oxygen demand( BOD) and chemical oxygen (COD) refer to the oxygen required to biograde or to chemically oxidize the waste constituents of the effluents. However, during weekend and end-of-crop washing, the effluent volume is low but hte COD content is high. Certain factories have special or sedimentation ponds for wastewater which is released gradually into the irrigation network. This practice appears to be a better approach than diluting the objectionable effluent with raw water to the Government effluent discharge norms.
