Composition and improved PH driven method for wastewater separation using an amphoteric dicarboxylate and a cationic destabilizer composition |
| abstract |
Improved separation of emulsified hydrophobic organic soils can be obtained from aqueous effluents using an amphoteric dicarboxylate surfactant material in combination with cationic destabilizer or floeculent materials. Such a treatment in combination with an acidic pH adjustment causes the rapid separation of hydrophobic organic soils from the aqueous stream, the treated aqueous stream is environmentally compatible. Improved laundry detergents comprising an organic amphoteric carboxylate surfactant and selected nonionic surfactants provide both cleaning for fiber and fabric containing items soiled with substantial quantities of hydrophobic soil. The pH of an effluent generated in such cleaning processes can be adjusted to an acid pH and treated with a cationic material causing a break that permits rapid and substantially complete separation of the hydrophobic organic soils from the effluent. Residual concentrations of organic soil in effluent water can be less than 250 ppm and can be as low as 10 ppm. |
