Removal of Phosphate from Pharmaceutical Effluent Using Obligate Aerobes Derived from Fruit Waste

Abstract

Phosphorus pollution is a major concern for soil and water management. Phosphorus in water is found in the form of phosphate.Phosphate removal from different effluents by using various parameters like, Effect of Contact Time, Effect of particle size, Effect of fruit waste, Effect of pH, Effect of alum, Effect of dolomite. Mostly the removal efficiency of phosphate is obtained from Biosorption. In this present study using obligate aerobes derived from fruit waste as an adsorbent for phosphate removal. The reaction time, optimum pH, effective dosage of alum and effective dosage of dolomite were optimized. As a result dosage of fruit waste 10.0gm/100ml, reaction time of 4hr 20min, pH of 8, by adding the alum to the effluent the reaction time is reduced from 4.20hr to 3 and also by adding the dolomite to the effluent the reaction time is reduced from 4 to 3.30hr under optimized conditions.
The phosphate concentration is decreased from 160ppm to 4.07ppm in 2.5hrs at optimum conditions using alum.
