Cationic polymer composition for sludge dewatering |
| 摘要 |
<p>An improved sludge dewatering composition is prepared by (i) forming an aqueous solution of a water soluble nonionic monomer, a cationic comonomer, and a cationic polymer, (ii) emulsifying the aqueous solution in a sufficient quantity of hydrocarbon oil to form a water-in-oil emulsion, and (iii) polymerizing the monomers.</p> |
