Development of Modeling Equation and Kinetics of Phosphate Removal from Pharmaceutical Effluent

Abstract

Phosphates are the naturally occurring form of the element phosphorus, found in many phosphate minerals. Phosphates enter waterways from human and animal waste, phosphorous rich bedrock, laundry, cleaning, industrial effluents and fertilizer runoff. These phosphates become detrimental when they pass over fertilize aquatic plants and cause stepped up eutrophication. A modeling equation was developed to known the phosphate removal with time. The proposed model equation for the removal of phosphate is YP = -0.843t + 160.3 and the model showed good agreement with experimental data (chemical precipitation method) and is significant compared to other methods in the removal of phosphate from pharmaceutical industry using chemical precipitation process. And the phosphate removal efficiency was with CaCO3 is 97.45%. BOD is reduced from 74 to 28 ppm and COD is reduced from 1045 to 279ppm. The order of reaction was found out by plotting a graph between -rA and CA. From the graph we can say that reaction is of first order and the rate constant is calculated from the values of -rA and CA and it is 0.0303min-1. The time required for the phosphate removal in pharmaceutical effluent was calculated by using batch reactor performance equation and the reaction required is found to be 2.03hrs from the calculations and 2.5hrs from the experiments performed. The standard error obtained from the experimental data is ± ૙. ૛૜૞.
