Aii?a?oe, I.I. Aaeaeeia, A.A.PREMEMBRANE TREATMENT OF DRAINAGE WATERS FROM DUMPS OF SOLID DOMESTIC WASTES The efficiency of the premembrane purification of drainage waters from solid domestic waste dumps has been investigated using oxidizers, adsorbents, coagulants, and flocculants. The optimal PH values of the coagulation processes and optimal concentrations of introduced coagulants have been determinated. It has been shown that the coagulation by basic aluminium sulfate is much effective for the purification of drainage waters as compared with all applied methods. The results of tests of the experimental plant including the units of coagulation and demineralization by the reverse osmosis of drainage water from solid domestic waste dumps have given the possibility to obtain permeate meeting norms for discharge it in sewerage.
