Assessment of emerging techniques adsorptive bubble separation (ionic flotation / precipitation flotation and flotation of colloidal adsorption) surface-active substances in aqueous systems

Abstract

Evaluation of the technological techniques for adsorptive bubble separation of the surface-active substances from aqueous systems. Establishing correlations with surface-active substances in structural sensitivity to the implications of separating the aqueous systems with specific matrices contamination. Performance Analysis of the adsorptive bubble separation process in conjunction with conventional methods of treating water contaminated with surface-active substances; dissolved air flotation and electro flotation-electrocoagulation Investigation of degradation processes by phooto-oxidation of organic pollutants (alkyl sulfates, alkylbenzene sodium) in foams. Techniques and technologies for the separation of substances by adsorption flotation and colloidal -precipitates flotation. Main result - Treatment technology for effluents heavily contaminated with anionic surfactants, best for alkylbenzenesulphonates or alkanesulphonates. The technology allows achieving low residual concentrations, so the effluent can be further be processed by biological treatment steps.
