Drinking water grade PAM
Drinking water grade PAM is mainly be used in raw water treatment,sugar making,fermentation,etc..PAM can be added in raw water for the purpose of settling and flocculating,which can effectively reduce the dosage of additive such as poly-aluminum, thus avoid producing too much sludge. Recommended products: A556PWG, A656PWG.In sugar making industry,PAM is efficient in the flocculating and precipitating of bagasse from sugar solution.After the treatment, clear sugar solution is obtained.Recommended brand :A756PWG. Choose the mixure of PAC and PAM for the separation and purification of sugar cane molasses to the best effect.Recommended brands: A556PWG, A756PWG. In fermentation industry, PAM can be used in the recycling of solid content(%) from diluted thin stillage water separated from alcohol.Recommended brands: A556PWG, A756PWG; In the fermentation process of zhongshengmycin, it is advisable to use PAM as a flocculant that will remarkably improve the liquid-solid separation performance.Recommended brand:C8040PWG.

Usage and dosage:
a, The concentration of the solution of these products work best in 0.1-0.4%, and neutral non-salt water is preferred to prepare the solution;
b, When being dissolved, sprinkle anionic polyacrylamide product evenly into the water,control the stirring speed within 50 ~ 200rpm. Heat if necessary (< 60℃), which can accelerate the dissolution;
c, Adjust the PH value of the solution to be treated to have the best effect of anionic polyacrylamide product (experiments are needed to determine the best PH value and the dosage of these products);
d, If flocs occur when anionic polyacrylamide product mixed with solution to be treated, slow the stirring speed to promote the growth of flocculant and accelerate the settlement.

Polyacrylamide (PAM) is a general term of acrylamide homopolymer or polymer copolymerized with other monomers. It is one of the most widely used varieties in water-soluble polymers. Because the structural unit of polyacrylamide contains amide group and is easy to form hydrogen bond, it has good water solubility and high chemical activity. It is easy to obtain a variety of modifiers with branched chain or network structure through grafting or cross-linking. It is widely used in petroleum exploitation, water treatment, textile, papermaking, beneficiation, medicine, agriculture and other industries, and is known as "Baiye assistant". The main application fields abroad are water treatment, papermaking, mining, metallurgy, etc; At present, the largest consumption in China is in the field of oil production, and the fastest growth is in the field of water treatment and papermaking.
