Toxicity of river water is largely determined by their self-purification processes, in particular the sorption of pollutants by suspended substances. Sorption ability of SS river water depends on the quality of incoming water, the species composition of plankton and its production characteristics. Studied the sorption capacity of SS river water in the release of treated effluent. We show that the SS with cleaning facilities (active sludge) have a higher sorption ability as compared with mineral particles. This sorption capacity of active sludge depend on water treatment technology.
