Are polyacrylamide products effective? How should I use this product?
Polyacrylamide is a linear organic high molecular polymer, and it is also a high molecular water treatment flocculant product, which can specifically absorb suspended particles in water, act as a bridge between particles, and make fine particles form a relatively Large flocs and accelerated sedimentation. This process is called flocculation, because of its good flocculation effect, PAM is used as a flocculant in water treatment and is widely used in sewage treatment.
how to use:
(1) Polyacrylamide dry powder or polyacrylamide emulsion usually cannot be used directly. It needs to be diluted and dissolved with water according to a certain proportion, and then used after the dissolution is complete;
(2) The water for dissolving polyacrylamide products must be clean tap water, not sewage;
(3) Weigh the polyacrylamide product that needs to be dissolved, and the dissolution ratio is usually 0.1%-0.3%;
(4) There needs to be a dissolving pool at the site of use, and a stirring device is required. The stirring speed is 60-200 rpm/mg. The dissolving and stirring devices cannot be made of iron, and iron ions will cause product degradation;
(5) The stirring time is 40-60 minutes, and the dissolved aqueous solution is a transparent, colorless viscous liquid;
(6) Add the stirred solution into the sewage that needs to be treated, mix thoroughly, and finally flocculate into agglomerates and settle in water, and the cement is separated.
