Vermicomposting of textile sludge using Perionyx excavates

Abstract

      The present study investigated the potential for textile sludge treatment using vermicomposting process by Perionyx excavatus. Composted water hyacinth was added to improve the nutritional values of sludge. Different treatments were created with different ratios of composted water hyacinth mixed with textile sludge as feed mixture. Treatments were put in darkness and their moisture content was maintained at 50 - 60%. pH, total nitrogen, total phosphorus an Cr3+ content were measured during initial and final period of the study. Fertilizer potential of end product was evaluated based on the nutritional values of the product.
