The usage principle and application of polyacrylamide

Wastewater treatment process is a very critical aspect of flocculation process, whether at home or abroad, in many of the most widely used in water treatment processes, the most common practice, flocculation often determines the quality of the health of the follow-up process final effluent quality and cost, the choice of flocculants for improving water quality, reduce the cost of water has an important technical and economic value.
Depending on the chemical composition of substances,inorganic flocculants can generally be divided into categories flocculants, organic polymer flocculant( PAM-Polyacrylamide) and microbial flocculant. Inorganic flocculants fewer varieties, mainly aluminum, iron, and other low molecular weight polymer hydrolysis of salts and inorganic polymer flocculants, etc..
Our new production line on two large-scale production to further increase the production of organic polymer flocculants(anionic polyacrylamide,cationic polyacrylamide) are mainly synthetic organic polymer flocculant and modified natural organic polymer flocculant.
What principles are to be followed in the use of polyacrylamide ? We briefly summary below:
A granular polyacrylamide flocculant can not be directly added to the sewage cast before using it must first be dissolved in water, its solution to deal with sewage.
2, granular polymers dissolved in water should be clean (such as water), not sewage. Temperature of the water can be, generally do not need to heat the water temperature is below 5 ℃ dissolve very slowly. Temperature increase the dissolution speed, but above 40 ℃ will accelerate the degradation of the polymer, affect the results. general water are suitable for the preparation of the polymer solution. acids, alkalis, high salinity of the water is not suitable for preparation.
3, the choice of the concentration of the polymer solution, booming recommends 0.1% -0.3%, i.e., 1 liter of water was added 1g-3g polymer powder.
