Effluent samples were collected from a sugar industry at Peshawar (Pakistan) in the sugar-cane season (Dee-March, 2002) and beat season (May-August 2002). The samples were chemically evaluated for different parameters. Total suspended solids (fSS), chemical oxygen demand (COD) and biological oxygen demand (BOD) values were found higher than the threshold limits and can therefore create aquatic problems in the Kabul River. A treatment process (mainly physicochemical) has been developed to reduce the harmful effects of the sugar mills effluent and to safeguard the aquatic habitat of the Kabul River. The efficiency of the treatment process in terms of BOD and COD reduction was found to be 96% and 95% respectively, which signifies its suitability to be used as an appropriate process. The process has the potential to protect the water bodies from further deterioration.
