It was summarized that the research progress of treatment techniques for potable water production from tiny-polluted raw-water. Based on the status of polluted surface water in China, the development of techniques for tiny-polluted raw-water treatment like pre-treatment techniques, advanced techniques and enhanced coagulation, and so on, were reviewed on the basis of representative references. It was pointed out that among these treatment techniques for tiny-polluted raw-water, selecting effective coagulants for specific raw water under the existing equipment condition of potable water plant, could improve the produced water quality remarkably with lowest cost. And it was an economic method for tiny-polluted raw water treatment and becomes a hot topic of research work in the area of raw water treatment. Furthermore, Based on the wildly used coagulants in domestic industry and combined with the region and season characteristics of the raw water, the development of universal and special coagulants with high quality could improve the techniques of our country in tiny-polluted raw-water treatment markedly and ensure the quality of potable water fundamentally.
