ASSESSMENT OF IRRIGATION WATER QUALITY AS DETERIORATED BY EFFLUENT DISCHARGED FROM MAJOR SHRIMP PROCESSING INDUSTRIES OF RUPSHA UPAZILA, KHULNA, BANGLADESH

A Comparative study was carried out in different shrimp processing industries at Rupsha Upazila under Khulna district from January 2010 to December 2010. In the experiment, some water quality parameters were determined sketch nutrient dynamics of experimental area. The contents analyzed for measuring temperature, pH, EC, salinity, sodium adsorption ratio (SAR), soluble percentage (SSP), hardness and major ionic concentrations. temperature samples ranged 29.1°C 29.3 °C pH varied 8.0 8.12 which reflected neutral alkaline nature. values SAR, SSP 4.28 8.65, 71.24 81.847 percent 239.1 312.3 mg L-1, respectively. Among five hazardous classes four High (alkali) content with medium salinity hazard. So, result, it may be concluded that appropriate sustainable management technologies need incorporated control water.
