[Track membranes in the filtration technique of determination of the quality of water from bacteriological values].
The paper describes a new class of microfiltration track membranes (TMs) proposed for laboratories to carry out a sanitary water bacteriological test. TMs have a strictly reference pore structure, a low sorption capacity do not contain the components that able to migrate into the filtrate, they are noted for a screening mechanism of holding microparticles onto the surface. The TMs made in Russia, the reticular membranes "Vladipore", and the foreign Millipore membranes certified by the international standards were comprehensively assessed. TMs are superior to the membranes manufactured in Russia at the moment in a number of basic properties that are most essential for the study of water quality and to foreign certified membranes in physical parameters, the specific features of growth of coliform bacteria, the rate of performance of an oxidase test, and the efficiency of retention of various microorganisms.
