Abstract:

The slightly polluted raw water in Yao river was treated separately by the bio-contact oxidation process and the conventional water purification process.The experiment results show that the bio-chemistry process can save more coagulants of above 50% and liquid chlorine of about 80% under the same conditions of water treatment than the conventional process and has a remarkable economic benefits.

Key words: bio-contact oxidation, water purification, polluted raw water, coagulants, liquid chlorine
