EFFICIENCY OF WATER IMPURITY COAGULATION WITH COARSE-GRAINED CONTACT BED

https://doi.org/10.31675/1607-1859-2018-20-6-167-178

Abstract

The paper describes theoretical and experimental studies of solid mineral water impurity coagulation during mixing with aluminum sulfate coagulant solution in the contact bed with the grain size of 10, 30 and 50 mm. It is shown that the values of velocity gradient and Camp criterion, which together with coagulant dose determine the flocculation efficiency, are functions of the specific surface area of pore space of the coarse-grained bed. A comparison of the efficiency of coagulating natural water containing kaolinite clay particles in the amount of (1.11–1.15)10–4 is given when mixing with aluminum sulfate solution by means of a mechanical mixer in a free volume and in coarse-grained bed clarification at a subsequent precipitation of treated water.
