Anionic polyacrylamide APAM
[ APAM Properties ]
According to different uses, anionic polyacrylamide is sorted into two kinds of manufacturing technique.
1. Homopolymerization ( hydrolysis and posthydrolysis of Non-ionic polyacrylamide).
2. Copolymerization ( acrylamide, acrylic acid or sodium acrylate ).
Polyacrylamide has received ISO9002 quality system certification. Product type : PAM-DFH
[ Anionic Polyacrylamide Uses ]
1. APAM In The Treatment Of Industrial Waste Water
Anionic PAM widely used in the treatment of the sewage with suspended grains, high concentration, postive charges and mid or sidali PH value, the waste water from a iron and steel plant, an electroplating factory and a coal washing works, and metallurgical waste water
2. Anionic PAM In The Treatment Of Drinking Water
Generally the DFH-H-3's molecular weight is appropriate. For many drinding-water factories, their water sources are from rivers, and have high mud and mineral content and high turbidity degree. Though APAM is passed through the sediment and filtration processes, it isn't still in conformity with the requirements, and must be added with some flocculants. In the past, the inorganic flocculants were generally used and with a large adding quantity, resulting in raising the secondary mud quantity. Now the anionic polyacrylamide is used as flocculant, its adding quantity is only 1/50 of inorganic flocculant, and its effect is several times better than the inorganic flocculant. For some rivers with serious pollution due to organic matter,anionic polyacrylamide is well recommended that the inorganic flocculant is used together with the cationic polyacrylamide (PAM-H-4 or PAM-H-5) made in our company.
3. The Recovery of the Starch Loss And Grain Stillage From A Starch Plant and AN Alcohol Plant
If the PAM-H-2 is added into the waste water from the starch plant, the starch grains will be flocculated to sediment. Then this sediment is through the filter-pressing process by a pressure filter, caked and used as feedstuff. The grain stillage from an alcohol pant can also be dewatered by the PAM-H-4 and recovered through the filter-pressing process.
