This creates great the wastewater which not only creating nuisance to human nuisance to aquatic life and human health. The waste health but also to the environment in various ways phosphorus water contains various contaminants like heavy metals, is the one of the essential nutrient in waste water which occurs sulphate, nitrates, phosphate, suspended solids etc. The as phosphate. But excessive discharge of phosphorus from industrial or domestic waste disturbs aquatic balance and it permissible limits are set by various government reduces the level of oxygen in waste water. The leading effect agencies for each parameter. 1
caused due to excessive phosphate is ‘Eutrophication’. There are various physical, chemical and biological techniques invented to remove phosphate from waste water. Now a day more attention is given to utilization of naturally available materials for treatment of waters various naturally available materials such as fly ash fruit juice residue, sugarcane baggage, rice husk are used which are cheaper than chemical treatments. Introduction of rice husk in treatment of phosphorus solves the problem of disposal of rice husk and reduces cost of treatment. The activated rice husk ash is used s an adsorbent. According to various studies rice husk provides cost effective and efficient method of phosphate removal.

1.INTRODUCTION The earth planet is having about 79% of water. Water is essential for all living organisms for their growth and survival. Due to development in industry sector people’s standard of living and the commercial sectors huge amount of waste water is generated which © 2017, IRJET

The site for experimentation at river “Mutha”. The river is located in Pune district in western Maharashtra. It arises in western ghats and flows eastword until it merges with the Mula river in Pune. . There are 12 industrial estates and IT parks developed by Maharashtra Industrial Development Corporation (MIDC). Small scale industries are also located at various places such as Hadapsar, Lonavala etc. Compared to total number of registered industries in the state, 10.09% of industries are located in Pune district alone. Their waste has to be discharged. Although, not all the industries violate the limits of discharging waste in the river, only a small percentage of industries create a problem and add to pollution in Mula-Mutha. Apart from this, human waste, daily sewage, plastics and other toxic substances worsen the situation more which requires urgent treatment solutions. ISO 9001:2008 Certified Journal
