Assessment on Water Quality of Waste Water in Sugar Industry and Its Impact on Environment

Abstract

This present study was conducted to determine the physico-chemical properties of sugarmill waste water. Samples were collected from Joypurhat sugarmill area. Different parameters such as pH, EC, TDS, DO, BOD, COD and Na+, K+, Ca2+, Mg2+, Cl−, , etc. of these water samples were analyzed. There was a wide variation in waste water quality of before production and after production of sugarmill. This discharged waste water did not maintain standard values of inland surface water quality (according to Department of Environment, Bangladesh). Waste water from different sugarmills was also studied here. The waste water of Karu & Kong was better than other six sugarmills. This study was done to measure quality of sugarmill waste water and to know the effect of it on surrounding environment.
