Abstract

The seasonal turbidity of the Narin River is presented for the selection of an effective treatment method by soaking in coagulants in spring and autumn. The sedimentation process is characterized by the deposition of highly turbid river water.Low water temperatures require an increase in the optimal doses of the coagulant by almost two times, and the flocculant by more than two times. It has been shown that the color of the water varies by 5-10 degrees, and the maximum transparency is achieved in the zone of optimal pH. Empirical dependences of the coagulant dose on the initial water color are given, taking into account its temperature. The efficiency of low-temperature water purification essentially depends on the flocculation process, the duration of which increases several times during the period of low water temperatures. Under these conditions, the most appropriate and effective method of clarification is pressure flotation.
