Abstract

This paper shows the importance of the equation for the optimum dosage of coagulant and its application to water treatment plant. The optimum coagulant dose during the operation of the water treatment plant "Gorina" in Serbia was determined in a laboratory by means of the jar-test, which fully simulates the conditions of flocculation chambers in the facility. Experimental data fitting yielded a polynomial equation that can be used for the determined coagulant doses. In general, without a jar test, the equation can be used to reliably determine the optimum coagulant dose for application in the water treatment plant, which will purify raw water to a proper inter-stage turbidity value, and will guarantee that the treated water quality will correspond to the Regulation on Hygienic Quality of Drinking Water. The presented analysis of trial run results for the water treatment plant "Gorina" in Serbia showcases the benefits of applying the equation of optimum coagulant doses to achieve top drinking water quality.
