CHARACTERISTIC STUDY ON DOMESTIC WASTE WATER BY NATURAL ABSORBENTS USING MULTIMEDIA FILTER TECHNOLOGY

This project deals with the characteristics study on treatment of domestic sewage and utilization of treated sewage for irrigation can prevent pollution of water bodies and reduce the demand of fresh water in irrigation sector. Providing treatment facility for all polluting sources is difficult and also expensive. Hence there is pressing demand for innovative technologies which are low cost, require low maintenance and are energy efficient for water treatment. Filtration is a process for separating the contaminant from wastewater by passing through the porous media. Experimental study was carried out to upgrade the conventional treatment process by introduction of multiple media. An attempt was made to treat the domestic waste water generated at SRIT, Perur, Coimbatore, by using a lab scale filter media setup. The treatment process was undertaken along with several laboratory experiments. The lab-scale reactor was approximately designed. The reactor was packed with different combination of packing media such as sugarcane bagasse, coconut coir, rice husk. The treated sample was collected after 24 hours and 48 hours. BOD removal efficiency has been obtained. The performance assessment parameter such as COD removal, BOD removal, pH variation, Total solids, Dissolved solids, turbidity was adopted. Thus providing a economically feasible and eco-friendly technology to improve the quality of life of rural people
