Abstract

Wastewater from the textile industry belongs to the category of the most polluted industrial wastewaters and poses a special danger to the aquatic environment. The aim of this study was to examine the membrane retention efficiency of textile wastewater (TOV) with commercial ultrafiltration (UF) membranes (GH, GK, PT, PU, PW, MW) with a wide range of molecular weight cut-off (MWCO), 2–50 kDa. The tested UF membranes resulted in a reduction in colour and colour intensity from 56.35 % to 97.93 %. Membrane of lower MWCO values (below 3 kDa) may be suitable for removing dyes from the real TOV sample.
