Phosphorus could be eliminated by improved organic phosphorus removal and also by chemical precipitation, generally with salts of iron (e. g. ferric chloride), aluminium (e. g. alum), or lime. Chlorination, Ozonation and also Ultraviolet (UV) light are one of several methods to wastewater sanitation. SEWAGE TREATMENT PLANT PROCESSSewage can be dealt with at the site where sewage is produced or at a central treatment plant. Pretreatment is where large items, grit, fat and oil are eliminated to guarantee the downstream treatment phases operate at the preferred performance levels. With the aid of a bar screen, products such as trash, tree arm or legs, leaves, branches, and various other big objects are gotten rid of from the raw sewage to stop any damages or clog the pumps as well as sewage lines. Grit such as sand, crushed rock, cinders, as well as natural materials are gotten rid of using a grit channel or chamber where the speed of the inbound sewage is adjusted to allow negotiation. Grit elimination helps in reducing formation of hefty deposits in aeration storage tanks, aerobic digesters, pipes, channels and shield moving mechanical equipment from abrasion and also accompanying abnormal wear. Equalization tanks temporarily hold incoming sewage and also serve as a way of watering down as well as distributing batch discharges of harmful or high-strength waste.
