Natural water suspension matter and limb matter grain diameter are very trivial.Be to dislodge these matter being backed by the means drifting along curdling generally , that is ,add the appropriate coagulant , blend through sufficiently in raw water, let colloid stability be spoiled the polymer (coming off after steady) and being situated between with coagulant water looks at and appraises an adsorption , makes a pellet have the flocculation function. But, that flocculation pool purpose is to create appropriate waterpower condition makes this have flocculation function pellet assembling, to form bigger flocculation body (catkin granule) in contacting middle mutually. But therefore, flocculation pool designs thinking that indeed or not, effect being related to a flocculation, the flocculation effect has direct impact to follow-up treatment precipitayion effect. The flocculation mixer is flocculation pool mechanical rabble device , it is used for the waste water treatment mixing process mainly. Design the design having mentioned flocculation pool originally, the mixer design and whose process flow.
