How to Solve the Caking Phenomenon of Flocculant PAM in Water
In order to reduce the agglomeration of flocculant in water, we need a method of dosing. In the preservation of anti-caking should pay attention to, must be placed in a cool, dry, ventilated environment. If it is in the process of dissolving, add half of the water in the pool first, then stir evenly and slowly add dry polyacrylamide powder at the same time.
Polyacrylamide flocculant is an organic polymer flocculant. Its molecular weight is relatively large. Generally, it is in the order of millions or tens of millions. When it dissolves, it will swell first and then dissolve slowly. If the amount of polyacrylamide is large and it can not be added evenly and slowly, polypropylene will dissolve slowly. The acrylamide first contacts the water part, then begins to swell, then the surface area becomes larger, and then encapsulates the untouched part (you can peel off the fished flocs, the middle is dry, not contaminated with water), so some insoluble polyacrylamide groups are formed. At present, most sewage treatment plants generally use manual dosing (if the automatic feeder is used instead, it not only saves manpower, but also avoids this situation as much as possible). It is suggested that the water should be stirred up first, and then slowly and evenly added above the water column washed out from the intake, so that the medicine can be flushed into the water along the current, so as to reduce the probability of agglomeration, in addition, the contact between the medicine and the inner wall of the dissolving tank should be avoided as far as possible.
We can fully dissolve the flocculant powder in the process of using the above-mentioned points. The combination of flocculant and wastewater treatment equipment makes wastewater treatment more effective and effectively solves the problem of wastewater treatment. Therefore, when adding medicine, pay more attention to the cooperation between adding medicine and equipment to achieve the greatest effect.
