Enhanced coagulation two times was better than one and the result reached the top when the first time of congealing during 90 s to 120 s.

Although the canal water quality is very complicated, it can be turned into influent of the reverse osmosis by second coagulation and enhanced coagulation successfully.

To address the requirements and characteristics of low-temperature(≤4℃) and anaerobic domestic sewage treatment in Qinghai-Tibet Plateau,the mechanism of advanced treatment of enhanced flocculation and catalytic electrochemical oxidation of cold domestic sewage in the Plateau was studied.

Progress on removal of organic matter in micro-polluted source water by enhanced coagulation;

Research on integrative waterpower enhanced coagulation device and its optimized operation in treatment of micro-polluted river water;

Studies on the treatment of the Beidu River raw water with low turbidity and low temperature by enhanced coagulation;

Effect of enhanced-coagulation with PPC on blue-green algae and chroma removal and its causation;

Experi-ments on removal of color from Tai Lake water with PPC indicate that,enhanced-coagulation of PPC can remove color from Tai Lake water enhance the color removal rate by small dose PAC and is not diffected by the pH at all.

Describes the removal of blue algae from Tai Lake with PPC and concludes from the test results that the enhanced-coagulation with PPC can efficiently remove blue algae, reduce water chroma, and expand the range of optium coagulator dose and raise the anti-disturbing capacity.

High strength semi lightweight concrete (HSSC) is a kind of new concretematerial which refers to the coarse aggregates compounded with normal weightaggregate and lightweight aggregate.
