Effluent produced by the cellulose and textiles industries contains inorganic and organic substances. These can only be removed by pretreatment of the wastewater followed by biological treatment. The microbes help to accelerate the degrading process. Some bacteria are isolated from environment playing a fabulous role in improving the quality of waste water. The present study was conducted to find out the potential of bacteria for reducing the hardness and total dissolve solid in effluent. Three microbial cultures SLB8, QY, QAC showed capability to reduce TDS and Hardness and increase the pH. Maximum TDS reduced by SLB8 13% followed by QY 7% and QC 5% and Hardness decreased by QAC 35% followed by SLB8 28 % and QY 20 %. Maximum pH value was increased by SLB8 6.63 followed by QY 6.57 and QAC 6.0. Such method is very economic and eco-friendly, it can be useful for large scale effluent treatment.
