Reducing the total dissolved solids in textile effluent: An integrated approach

Abstract

The present research investigated the reduction of total dissolved solids (TDS) of untreated textile effluent by means of integrated approach. Biological method of TDS reduction using native microorganism were not successful as they were not effective in TDS reduction. Chemical method of treating the waste water using alum produced more sludge and increased the TDS content of the effluent. The physical methods like membrane filters, micro filters, ultra filters, nano filters and reverse osmosis were successful in TDS reduction but fetch additional cost. Integrated approach of biological and physical methods would solve the TDS problem and lower the treatment cost.
