Experimental-theoretical substantiation of the previously formed sediment’s application as the water clarification process intensifier

Year: 2020

Abstract: An attempt was made to experimentally and theoretically substantiate the use of the previously formed sediment for clarifying water. The water-pipe sediment contains a large amount of aluminum sulfate, which, when introduced into water, promotes hydrolysis, sorption, and adhesion. When the recommended doses of spent sediment are introduced into water before entering the sedimentation tanks, the suspension is destabilized, most of it falls into the sediment, and the remaining destabilized part is exposed to the coagulant introduced sometime after the sediment is introduced, which contributes to the renewal of the suspension activity in the sorption and adhesion phenomena. In addition, the sediment recycling process can be considered as sorption. The electro kinetic potential is in the range of 15-20 mV using the sediment recirculation method.
