primarily from a combination of primary‚ secondary‚ and tertiary sewage sludges. Biosolids do not contain the coarse grit and screenings removed from raw wastewater during preliminary treatment steps or ash generated from incineration of sewage sludge. Another type of biosolids may be derived from domestic septage‚ the solid or liquid material removed from septic systems‚ portable toilets‚ and other systems that receive only domestic sewage.

SEWAGE TREATMENT Sewage is a mixture of domestic and industrial wastes. It is more than 99% water‚ but the remainder contains some ions‚ suspended solids and harmful bacteria that must be removed before the water is released into the sea. The treatment of wastewater is divided into three phases: pretreatment‚ primary treatment and secondary treatment. Pretreatment Large solids (i.e. those with a diameter of more than 2cm) and grit (heavy solids) are removed by screening. These are disposed of in

and valuable resource. While industrial growth and unplanned water utilization for agricultural use have depleted ground water levels in many parts of India‚ the growth of urban clusters have brought pressure on available water. Increasing levels in sewage and industrial effluents have created the threat of pollution. Against this context of growing concerns about water‚ its recycling becomes important‚ for beneficial purposes such as agricultural and landscape irrigation‚ industrial processes‚ reuse
