摘要：Drinking water is a vital resource for all human beings and the access to safe and clean drinking water isa major concern throughout the world. The water resources all around the world contaminated by industrial wastedisposal so it need of water treatment process. This study investigates about the various waste waters such as Sagoindustries, Dairy waste water, Dye waste water, Domestic waste water. The characteristics of the various waste watersare analysed and compared based on water quality parameters such as Turbidity, Biochemical Oxygen Demand (BOD),Chemical Oxygen Demand (COD), Total Suspended Solids(TSS), Nitrates, Phosphates, and Total Nitrogen (TN),Calcium(Ca). The water quality parameters permissible limits are compared with IS10500:2012, ISI10500:1991,WHOstandards. The waste water are analysed and find out in which contend is higher for fertilizer production. That wastewater sludge is used for fertilizer production. Finally the sludge is converted into natural fertilizer for growth of theplants. The treated waste water is used for agriculture.
