    Abstract: The process of continuous machine dishwashing, which can be carried out in single-tank or multi-tank machines, is improved by the machine-operated process disclosed. This is achieved, in particular, by treatment of the tableware at least in one process step with an acidic cleaning solution and in another process step with an alkaline cleaning solution, comprising the step s of: a) applying an acidic aqueous cleaning solution to the at least partly soiled tableware and b) removing the acidic aqueous solution and the soil in one or more following steps, the at least one alkaline treatment taking plac e before and/or after the acidic treatment and the alkaline and at least acidi c aqueous cleaning solution at least partially neutralizing one another.

    Abstract: Improved separation of emulsified hydrophobic organic soils can be obtained from aqueous effluents using an amphoteric carboxylate surfactant material in combination with cationic destabilizer or flocculent 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.
