Investigation on the effective disposal of sludge from a water treatment plant

Abstract Accumulation of water treatment sludge is a major environment problem in the purification process. Recovery waste constituents or reuse cost-effective method handling this environmental dilemma. The present study investigates suitability production bricks and recovery aluminum from accumulated at Biyagama drinking plant (BDWTP) Sri Lanka. chemical parameters total organic carbon, pH, nitrogen content, phosphorous heavy metals, cation exchange capacity samples were analyzed different turbidity periods. was investigated both by acidic alkaline leaching processes. A mixing ratio 3:1 (clay:water sludge) found to be suitable for manufacturing having compressive strength, efflorescence, absorption according SLS 39:1979. metal composition manufactured compared with clay sludge. impact current landfilling estimated analyzing leachate COD, NO3-, NO2-, PO43-, free NH3, SO42-, metals. leachability also establish its as an eco-friendly product.
