Cationized polyacrylamide solves the problems that should be paid attention to in sludge treatment
A customer inquired about the product manager of cationic polyacrylamide: the actual effect of cationic polyacrylamide to solve sludge treatment is not very ideal, why?
When the cationic polyacrylamide is used for sludge treatment, attention should be paid to the actual operation matters, so that the cationic polyacrylamide can play a stronger role in the sedimentation of the inclined plate sedimentation tank. The following lists the actual new projects in actual operation.
First of all, the consideration of work pressure has a great harm to the specific resistance of the sludge: after experiments, it is generally found that the work pressure gradually increases with the consideration of the work pressure. Of course, the rate of the consideration will also slowly accelerate. According to the detection and calculation method of specific resistance, the specific resistance of sludge is proportional to the excessive working pressure of the commodity.
Secondly, pay attention to the PH value of the wastewater, because the pH value of the wastewater often has a certain harm to the important links of sewage treatment, and it is also a very critical hazard to sludge treatment.
Third, the mixing rate after adding positive ion polyacrylamide: if the mixing is insufficient, the positive ion polyacrylamide can not fully exert its own effect, so it must be fully mixed during application to avoid insufficient mixing. The production of acrylamide coagulant is not harmful to sludge treatment.
