Abstract

Textile Industries of Bangladesh confront the environment a huge threat. It produces a huge amount of sludge from effluent treatment plants that is a burden for industries for its high volume and proper treatment cost thereby a huge threat to the environment. The present study aims to characterize the solid sludge of textile industry in terms of pH, organic matter (OM), nutrient elements (N, P, K) and other metal elements through proper analytical methods. The average pH value of the sludge sample was 8.28 along with moisture content 60.64%. The average content of the OM of the studied sludge samples was 11.73% and the average values of N, P and K were 7.57%, 0.52% and 0.50%, respectively. The studied metal (Cr, Zn Mn, Cd, Pb, As and Cu) content of the sludge revealed that the toxic heavy metals Pb, Cd and As were not found in the samples. This study reveals that the amount of OM, N, P and pH is within the Waste concern compost standard (WCCS). The findings clearly show a potentiality of textile sludge as organic manure as they are rich in OM and plant nutrients and free from toxic heavy metals as well.
