Abstract

One of the secondary problems in compost production in our country is the high humidity (over 70%) in waste which produces MUNICIPAL SOLID WASTE LEACHATE. If it is not collected and controlled, this will produce environmental problems such as soil and groundwater pollution. Water treatment with chemicals is used to decrease microbial contamination of water. Coagulants, such as FERRIC CHLORIDE and alum, are usually used in a common process in water treatments, namely coagulation. A laboratory experiment was performed to study the effect of three different coagulants-COPPER SULFATE, FERRIC CHLORIDE and SODIUM BENZOATE-at the two levels of 40 and 80 mg/l and a control (pure leachate) on the microbial DETOXIFICATION and chemical properties of MUNICIPAL SOLID WASTE LEACHATE in a completely randomized design experiment (factorial), with three replications. The results showed that electrical conductivity and total soluble ORGANIC CARBON decreased in all treatments compared to the control (pure leachate), while changes in the PH of treatments was not significant. Data revealed that in different amounts of salts, 40 mg/l salt decreased the total number of microorganisms more efficiently than 80 mg/l while 40 mg/l FERRIC CHLORIDE, and both 40 and 80 mg/l SODIUM BENZOATE were more efficient in reducing the total number of microorganisms. COPPER SULFATE at 40 mg/l had a greater effect in reducing the number of fecal and non fecal coli forms, while SODIUM BENZOATE at 40 mg/l had maximum reduction in number of fungi.
