The article presents the results of public service enterprises wastewater biotesting, which contain surfactants and model solutions in comparison with the colloidal-chemical properties. It is established that the maximum allowable concentration of surface active agents coincides with the concentration of saturation of the adsorption layers, which is determined by the isotherm of surface tension. This allows you to replace the tedious and less accurate biotesting measurement to the surface tension of surface active agents solutions to normalize indicators of wastewater.
