Sodium Methallyl Sulfonate (SMAS) modified amphoteric flocculants possess dual charge characteristics and excellent permeability. They can fully destabilize sludge particles, deeply separate internal bound water and form rigid flocs, thus exhibiting far superior sludge dewatering capacity compared with conventional single cationic polyacrylamide.
- Dual charge synergistic effect
With both anionic and cationic functional groups, Sodium Methallyl Sulfonate (SMAS) modified amphoteric flocculants can fully neutralize surface charges of sludge colloids to complete destabilization, while single cationic polyacrylamide only relies on single positive charge with limited treatment effect. - Efficient removal of bound water
The sulfonate groups in Sodium Methallyl Sulfonate (SMAS) molecules enhance molecular penetration, penetrate into sludge internal structure and squeeze out interstitial water and bound water effectively, which ordinary cationic polyacrylamide cannot achieve easily. - Steric hindrance reinforces floc structure
The methyl branched chain structure of Sodium Methallyl Sulfonate (SMAS) provides obvious steric hindrance effect, forming dense, tough and pressure-resistant flocs that are not easy to break during filter pressing. - Strong adaptability to complex sludge
Sodium Methallyl Sulfonate (SMAS) modified products are resistant to salinity, pH fluctuation and organic interference, suitable for all kinds of industrial sludge and domestic sludge, with stable dehydration effect. - Lower moisture content of sludge cake
It can form compact sludge cake with lower water content, greatly reduce sludge volume and save subsequent disposal cost.
