Sažetak
The aim of this study was to investigate the performances of polyamide nanofiltration membranes during water reclamation. The study was conducted using nanofiltration-concentrates obtained from two different nanofiltration-drinking water-treatment plants placed in northern part of Serbia (Kikinda and Zrenjanin). Used nanofiltration-concentrates contained high concentrations of arsenic (45 and 451 μg/L) and natural organic matter (10.8 and 56.1 mgO2/L). Performances of polyamide nanofiltration membranes during water reclamation were investigated under various fluxes and transmembrane pressures in order to obtain drinking water from nanofiltration concentrates, and therefore reduce the amount of produced concentrates and minimize the waste that has to be discharged in the environment. Applied polyamide nanofiltration-membranes showed better removal efficiency during water reclamation when concentrate with higher content of arsenic and natural organic matter was used while the obtained permeates were in accordance with European regulations. This study shown that total concentrate yield can be reduced for ~5% at optimum flux value, in both experiments. Obtained result for concentrate yield under optimum flux presents considerable amount of reclaimed drinking water and valuable reduced quantity of produced wastewater.
