PRUCYTRUS” AS A COAGULANT AGENT IN WATER TREATMENT PROCESS

Abstract

Nowadays, chemical agents such as aluminum sulphate (alum), ferric sulphate or sodium aluminate, ferric chloride of polymer is the common coagulant that is used for water purification in water treatment technology. The chemical coagulants have a positive charge to neutralize negative charge of dissolved and suspended particle in the water. The suspended particles vary in source, charge, particle size, shape and density. The research study the potential influencing of soybeans and kaffir lime peels as organics coagulant, alternative to chemical coagulant in water treatment process. The effectiveness of coagulant will produce a floc, heavy and quickly settle out of the water treatment process. Therefore, the level of water turbidity before and after treatment is a main parameter monitoring. This study aims to reduce the rate of water turbidity and to produce organics coagulant agents for treating the water samples collected from Sungai Gabai, Sungai Langat, and Sungai Kancing. In the study, we focused on producing the optimum ratio of coagulant concentration to reduce turbidity. The method used based on experimental laboratory testing, whereas the water samples will be adding with soybean and kaffir lime peels that we called as Prucytrus coagulant. The experiment was carried out for Jar Test, DO,pH, and Turbidity testing with liquid and powder organics coagulants designed. The results showed that the best ratio for the Prucytrus coagulant with 3g/liter in powder base is the most effective coagulant for reduce turbidity in water samples.
