Abstract
This paper presents the results of research on the possibility of reusing collector-drainage waters through the application of membrane technology. Data are provided on the effectiveness of ultrafiltration methods using microporous membranes and nanofiltration to reduce salinity. The results demonstrate the impact of the initial water salinity on the efficiency of ultrafiltration and nanofiltration processes. The influence of the temperature of collector-drainage waters on the specific productivity of the purification process is also shown. Keywords: Collector-drainage waters, salinity, ultrafiltration, nanofiltration, selectivity, specific membrane permeability, concentration polarization.
