Conference paper


The improvement in wastewater quality cited at prime importance because the quantities of the water available in surface and underground sources are depleted at very fast rate from last several years. This depletion is going on due to rise in water demand for development of industrial zones and fulfillment of growing population. The direct disposal of untreated wastewater from domestic and industrial activities contaminates the available quantity of surface and subsurface water beyond its acceptable limits. The consumption contaminated water not only leads to various water borne diseases but also pose difficulties in industrial processes. The soil has sufficient voids and permeability which can be used as medium to trap the available solid contaminates from the wastewater. The soil quality and characteristics will helpful to develop the quality improvement system to trap out the solids from wastewater. The void ratio and concentration of solids are important parameters to be considered in development of experimental stratum so that it will avoid the contamination of water bodies and improve the quality of wastewater. The motivational objective of this study is to develop the economical and efficient natural quality improvement system for wastewater treatment by locally available resources especially in rural areas where the improper sanitation practices are in existence. Authors are involved in water quality improvement for Ausa Lake by DWAT (Decentralize Wastewater Treatment) system followed by Reverse Osmosis (RO) unit under DST (Department of Science & Technology, Govt. of India) project at Ausa town of Marathwada region of Maharashtra.
