Polyacrylamide flocculant PAM, commonly granular, there are emulsion type, according to the different charges can be broadly divided into
anionic polyacrylamide,
cationic polyacrylamide and
non-ionic polyacrylamide, molecular weight from 100,000 to ten million, molecular weight anionic > non-ionic > cationic, the specific choice of the type of model according to the treatment of sewage medium is different. In general, it is best to go to the site to collect sewage samples, test to determine.
Dissolve and dilute PAM with relatively clean water, if too much dissolved matter in the water, it will be unfavourable to the dissolution and flocculation effect of PAM, the dissolution time generally takes 40 to 120 minutes, the dissolution process is stirred by the mixer of the dissolving tank, but the stirring speed can not be too fast, so as not to interrupt the molecular chain of the PAM and affect its flocculation effect. Concentration is generally: anionic or non-ionic, the highest dissolved concentration of 0.5%, cationic can not be more than 1%, in the use of water in the second dilution, the dosage ratio is roughly: suspension data concentration of 1, add 0.01 number of flocculants.
1, more contact is the granular polyacrylamide, granular polyacrylamide should not be directly added to the use of clean tap water must be dissolved uniformly, and then added to the use of a certain proportion;
2, it is recommended that the concentration of polypropionyl acrylamide dissolution control at 0.1% -0.3%. General use and then the second dilution.
3, dissolved polyacrylamide slowly and evenly added to the water phase with stirring, the stirring speed should not be strong (stirring blade speed control at the end of the line below 8 m / s) so as not to cause the polyacrylamide reduction of cutting force decline; add material too quickly also formed into a group, the formation of the ‘fish-eye’.
4, the water temperature should not exceed 60 ℃, room temperature.
5, configured polyacrylamide solution storage, cationic PAM should not exceed one day, anionic PAM should not exceed two days to avoid degradation.
6, the solution should not contact with iron ions, iron ions are catalysts easy to make polyacrylamide decomposition.
7, pump material, it is recommended to use diaphragm or vacuum pumping or low-pressure centrifugal pump (due to high-speed rotation of the pump blade is easy to make polyacrylamide degradation).
