Assessment of Physical and Chemical Contents of Textile Sludge and Associated Risks on Public Health: In Case of Common Effluent Treatment Plant (CETP)


Industry Parks Development Corporation (IPDC) is constructing Eco industrial parks in different regions of the country along with its infrastructure to build cleaner and resource-efficient production technologies and practices that reduces economic growth from unsustainable resource consumption and environmental degradation. To reduce pollution and reduce water resource depletion due to the existence of industry parks, Wastewaters must be treated to the level of acceptable standards to discharge or reused. Sludge from wastewater treatment plants is a serious issue because it can affect human and animals’ health, and also environmental quality. In this study, sludge from a textile and garment wastewater treatment plant was analysed regarding its physicochemical characteristics and disposal options. For this study, dewatered sludge sample was send to laboratory to determine the contents of sludge. The results showed that generated sludge has contents of pH (9.09), alkalinity (473.3 mg/kg), moisture content (17.99%), cadmium (4.970 mg/kg), lead (22.70 mg/kg), total phosphorous (5.3 mg/kg) and sulfur was not detected. These results indicate that the sludge has physical and chemical pollutants which have also public health interests. With the apprehending facts, IPDC is in trouble due to lack of sludge standards, management, and transportation and disposal site. Therefore, handling sludge is one of the most important challenges in this wastewater treatment plant.
