Sorption of synthetic surfactants by “Policon” materials.

The effect of the initial concentration of synthetic surfactant (SSF) in wastewaters on sorption was investigated, and Policon materials were recommended for use in the tertiary treatment stage where the concentration of SSF does not exceed 0.8 mg/dm³. It was noted that increasing the temperature of the effluents by 60° allows significantly extending the period of steady-state flow of the process and the depth of treatment remains high. The selectivity of Policon materials with respect to the SSF contained in synthetic detergents was investigated. The high efficiency of the materials in ultrafiltration of the components of synthetic detergents was demonstrated. [ABSTRACT FROM AUTHOR]
