Cationic polyacrylamide Precautions

Cationic polyacrylamide has except the turbidity, decoloring, adsorption, adhesion, and other functions, suitable for dyeing, papermaking, food, building, metallurgy, mineral processing, coal, oil field, aquatic products processing and fermentation industry waste water treatment of organic colloid content is higher. Cationic polyacrylamide use notice:

The size of the floccules: floccules is too small will affect the rate of drainage, floccules is lower the floccules constraints, more water and mud biscuits. After choosing the molecular weight of polyacrylamide can adjust the size of the floccules.

The sludge characteristics: the first point to understand the sources of the sludge, characteristics and composition and proportion. According to the properties of the different, the sludge can be divided into two kinds of organic and inorganic sludge. Cationic polyacrylamide used for disposal of organic sludge, relative anionic polyacrylamide flocculant used in sludge, inorganic alkali is very strong in the cationic polyacrylamide, and should not be used when strong acid anionic polyacrylamide, high solid content in sludge usually polyacrylamide dosage is large.

Floccules intensity: floccules under shearing action should be stable and not broken. Progress of polyacrylamide molecular weight or choose the suitable molecular structure helps to progress floccules stability.

Polyacrylamide ion degrees: for dewatering sludge, different ion flocculant are available after do small stop first selected, select the best suitable polyacrylamide, which can achieve the best effect of flocculant, and can make the dosage, at least, to save money.

Polyacrylamide dissolved:Dissolve good talents full play a role of flocculation, sometimes need to speed up the dissolved, then the concentration of a solution of polyacrylamide can think progress.
