Abstract
The basic characteristics of polyethylene terephthalate (PET) track me mbranes obtained from films 10 and 20 mum thick were examined. Membran es with pore diameters of 0.2, 0.4, and 1 mum were examined. Using a n umber of procedures, the following structural parameters of track memb ranes were determined: density and mean size of pores, bubble point, a nd pore-size distribution. The values of tensile strength and specific flow rates of water and gas were measured for both types of membranes . Membrane behavior during tap water filtration was studied. The advan tages of track membranes based on thicker films are discussed.
