(C3H5NO)N Polymer Coagulants Cationic Polymer For Sludge Dewatering

Cationic Polyacrylamide Flocculant Polymer Coagulants Sewage Sludge Dewatering Agent

Cationic polyacrylamide is a type of polyacrylamide. It is a linear polymer. Cationic polyacrylamide has many ionic species. The higher the ionicity, the more cationic monomers used in polyacrylamide, and the more expensive it is. Therefore, it has strong activity, can quickly and effectively adsorb impurity particles in water, flocculate to form hydrogen bonds, and mostly exist in the form of charged colloids.

Features of cationic polyacrylamide
1. Good water solubility, it can dissolve well even in cold water.

2. Less dosage, but good flocculation effect can be obtained. If used together with other inorganic flocculants, the water purification effect will be better.

3. Wide application range and strong adaptability of cationic polyacrylamide.

1) Polyacrylamide is an organic polymer compound, which can be divided into anionic polyacrylamide, cationic polyacrylamide and non-ionic polyacrylamide. It is white powder or granule, easily soluble in water, but the dissolution speed is very slow;

2) Anionic polyacrylamide is generally used as a flocculant for wastewater treatment, and cationic polyacrylamide is generally used for sludge dewatering;

3) When used as a flocculant, the dosage is generally 1-2ppm, that is, the dosage for each ton of wastewater treated is about 1-2g;

4) When in use, the anionic type is generally formulated into about 0.1% aqueous solution, and the cationic type can be formulated into 0.1%-0.5%;

5) When preparing the solution, first add water to the dissolving tank, then turn on the mixer, and then slowly add PAM along the vortex. PAM cannot be put in quickly at one time, otherwise PAM will clump to form "fish eyes" and cannot be dissolved;

6) After adding PAM, generally continue to stir for more than 30 minutes to ensure complete dissolution;
 

7) The dissolved PAM should be used as soon as possible. Generally anionic type should not exceed 36 hours. The cationic type is easily hydrolyzed after being dissolved. Should be used within 24 hours.
