Claims
- 1. A method of treating an aqueous system to separate material suspended therein which comprises adding to said system a sufficient amount for the purpose of a stable blend of a cationic water-in-oil emulsion polymer and a different cationic polymer in an aqueous solution.
- 2. A method according to claim 1, wherein the stable blend contains suitable solvents and surfactants in amounts sufficient to provide the stability.
- 3. Method according to claim 1, wherein said aqueous system is an influent or wastewater system.
- 4. Method according to claim 1, wherein said aqueous system is an oily waste system.
- 5. Method according to claim 1, wherein said system is in an emulsion breaking process.
- 6. Method according to claim 1, wherein said system is in a papermaking process.
- 7. Method according to claim 1, wherein said aqueous system is a sludge dewatering system.
- 8. Method according to claim 1, wherein said aqueous system is an upflow filtration system.
- 9. Method according to claim 1, wherein said system is a protein recovery system.
- 10. A method according to claim 1, wherein said cationic water-in-oil emulsion polymer and said different cationic polymer in aqueous solution are combined in a weight ratio of from about 5 to about 95 percent.
- 11. A method according to claim 1, wherein said cationic water-in-oil emulsion polymer and said cationic polymer in aqueous solution are combined in a weight ratio of from about 20 to about 80 percent.
- 12. A method according to claim 1, wherein said cationic polymer in aqueous solution comprises a mixture of cationic polymers.
