Product Details
Polyacrylamide for sludge dewatering is the treatment of sludge dewatering briquette by polyacrylamide manufacturers. The polyacrylamide aqueous solution polymerization method is used to change the physical and chemical properties of the surface of sludge particles, destroy the colloidal structure of sludge, reduce the affinity between sludge particles and water, and improve the dewatering performance of sludge accordingly. The flocculation and dewatering effect of concentrated sludge is obvious, and the moisture content of dewatered sludge cake is less than 80%, which meets the actual operating requirements, especially for municipal domestic sewage treatment plants and industrial sludge dewatering.
Sludge, a by-product of sewage treatment, is an extremely complex heterogeneous body composed of organic debris, bacteria, inorganic particles, colloids, etc. The treatment of sludge is necessary to avoid the "secondary pollution", which can make the sludge "resource" utilization. The moisture content of sludge is very high, and the sludge without dewatering treatment is generally 96% to 99.8, which is very large in volume. Polyacrylamide for sludge dewatering is used to improve sludge dewatering through chemical regulation. Dosing and conditioning are carried out before sludge dewatering to make charged inorganic or organic agents react with sludge. Through electrical neutralization, chemical bridging and other effects, water is separated from particles, and particles are condensed into large flocs, which can improve sludge dewatering performance.
Technical indicators of polyacrylamide for sludge dewatering:
| Appearance | Solid content | molecular weight | ion concentration |
| White particles | ≥ 88% | 600-18 million | 10-90 % |
