Management of Sewage Sludge for Environmental Sustainability

Abstract

Sewage sludge management is critical for reducing environmental pollution and its negative impacts on human health. Waste and wastewater are generally generated in large quantities in cities. Origin, collection process, and treatment all influence the quality of these sewage sludge wastes. Consequently, these wastes end up in a wide variety of places. Stabilization and processing results in the production of waste materials that may contain a variety of organic components. This method of controlling has the potential to contaminate the soil with unknown organic compounds since it usually involves dumping processed sludge on the ground. Thermal processing of raw sewage sludge, on the other hand, virtually eliminates this possibility. Most of the organic matter is converted to a basic, mineralized state of sludge. Perhaps the most urgent issue is sewage sludge ash contaminated with heavy metals. Apart from organic components, identifying toxic metals in sewage sludge ashes is substantially easier. For assessing environmentally safe sewage sludge from treated, processed and management process, chemical testing and analysis of sewage sludge can be extremely helpful and beneficial. Numerous analytical techniques are expected to contribute to the development and implementation of novel economic and environmentally sound methods of sewage sludge reuse consequently. Each treatment plant should have its own sewage sludge management system. Only then any management strategies can be considered ecologically and economically feasible. Sludge management gives comprehensive information on the treatment, reuse, and disposal of sludge. Thus, it is important to know the contaminants present in sludge and possible way in order to overcome the environmental risks and adopting acceptable possible treatment of sludge.
