CLARIFICATION SYSTEM IN WATER TREATMENT PLANT USING JAR-TEST

Abstract

The treatment of water for human consumption requires the application of efficient physical-chemical processes to remove impurities. The present study investigated the application of the Jar Test in Water Treatment Plants (WTP) to determine the optimal dosage of coagulants used in the clarification process. The objective was to evaluate the influence of aluminum sulfate concentration (Al₂(SO₄)₃) on the control of turbidity and water color. An experimental approach was used with systematized trials to identify the best treatment conditions. The results indicated that the optimal concentration of coagulant was 22.4 mg/L, associated with an ideal pH of 8.1, favoring the efficient removal of turbidity and color. It is concluded that the Jar Test is an essential tool for optimizing the coagulation process, ensuring greater efficiency and safety in water treatment.
