Abstract :
Wastewater the water supply of a community after it has been spoiled by use. Wastewater refers to all effluent from household, commercial establishments and institutions, hospitals, industries and so on. It is also includes storm water and urban runoff agricultural, horticultural and aquaculture effluent. Effluent refers to the sewage or liquid waste that is discharged into water bodies. It is wastewater originating from toilets and bathroom fixtures, bathing, laundry, kitchen sinks, clearness, and similar dirty water that is produced in households and public places. Water used to irrigate turf and gardens, swimming pools, roof drainage, surface runoff and storm water are all wastewater. Thanjavur District is the Rice Bowl of Tamil Nadu. The district stands unique from time immemorial for its agricultural activities and is rightly acclaimed as the Granary of the South India. Algal degradation of organic pollutants is a natural process which ensures a lower environmental impact compared with mechanical, physical, and chemical removal approaches of organic pollutants. The advantages of algae-based bioremediation are greater production biomass and high ability to accumulate, detoxify, or degrade xenobiotics and pollutants.
