FLOCCULATING AGENT IN GROUNDWATER TREATMENT

The effectiveness of groundwater treatment with a high amount of organic substances and general iron depended on the kind of oxidizing agent, the kind and dose of coagulant, and the time of sedimentation. The effectiveness of the sedimentation process increased with the length of time of the process, and its results depended most on the method of oxidizing Fe(II). From among the oxidizing agents used before the coagulation process the best results in terms of a decrease in colour, turbidity, the concentration of manganese and organic substances were obtained in the case of oxidization with potassium permanganate, and as far as the effectiveness of removing general iron was concerned oxidizing with dissolved oxygen
