“…In many cases, Dissolved Air Flotation (DAF) is an excellent choice for clarification process equipment (8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22). In the DAF process, raw water particles are flocculated and separated out of the water by floating to the surface rather than settle to the bottom of a basin.…”

“…Rapid mixing: A water treatment unit process of quickly mixing a chemical solution uniformly through the process water.Velocity gradient (G):A measure of the mixinn intensity (in units of per second) in a water treatment process. Very high velocity gradients (greater than 300 per second) are used for complete mixing and dissolution of chemicals in a coagulation process, whereas lower values (less than 75 per second) are used of the American Water Works Association 92(12),70-84.…”

“…The characteristics of the integrated effluent includes the higher contents of colloidal suspension, COD, the turbidity and colored substances [3] . Some new technologies have been developed for treating the effluent, such as super-filtration technology based on membrane separation [4] , biotechnology [5] , air-floatation technology [6] , high loading fluid bed [7] , and so on [8] . Every these technologies has itself advantages and disadvantages, and neither one of them is applied extensively in those mill for the technological or economic reasons.…”

A general three stages process to treat the integrated waste water in a laboratory scale, including anaerobic, aerobic and intensive coagulating treatment, was discussed in this paper. After being filtrated and coagulation simply, the effluent was treated with two steps of biological process combined with one step of intensive coagulation process. The result shows that the chemical impurities, including COD, BOD, colored substances and turbidity were removed efficiently,and after anaerobic biological treatment, effluent become easy to be biologically treated, and after aerobic aeration treatment, the BOD of the effluent from the clarifier was lower than 25 mg/l，and the BOD total removal ratio was as high as 90%. The result shows also that when poly aluminum silicate chloride (PASC) combing with APAM was effective to remove the colored substances more than 95%. Being treated for the three stages, the water quality of the treated effluent was higher than that discharge requirements by National Effluent Discharge Standards in China.
