Reuse of Textile ETP Sludge as Construction Material

Reuse of Textile ETP Sludge from Tirupur Region as Construction Material An Experimental Investigation

As per Tamil Nadu State Pollution Control Board (TNPCB) records, there are about 830 large units engaged in textile industrial processes in Tirupur alone. These industries have established eight Common Effluent Treatment Plants (CETPs) and many individual Effluent Treatment Plants (ETP), which are subjected to treat about 75,000 m3 of effluent per day genereated by textile industries. On the other hand, the sludge that retained due to the solids separation process in the treatment plants create lot of environmental problems due to lack of disposal methods. The practicing method of disposal of sludge in the Tirupur region is the Land filling method. Except engineered landfills, the rest of the sludge is disposed off by dumping it on the earth surface which may lead to ground water contamination and thereby results in socio-economic impacts. Many studies have been conducted in those areas and it needs for an alternative sludge management. The industrial solid waste of different nature is effectively utilized in Building materials as light weight cement.
