 Polyacrylamide for Industrial Sewage
Property
1. Anionic Polyacrylamide: Used for the high concentration neutral or alkaline sewage, or the one with positive charge. Eg: Steel mill sewage, electroplating plant sewage, metallurgical sewage, coal wasing sewage..
2. Cationic Polyacrylamide: Suitable for sewage treatment with negative charge or rich in organic matters. Eg: For waste water with high organic colloid content in dyeing, papermaking, oilfield, food processing etc. Especially suitable for the sludge dewatering of municipla sewage and sludge, papermaking sludge etc..
3. Non-ionic Polyacrylamide: Most suitable for the acidic suspended sewage.
