ABSTRACT
Textile wastewaters are rated as one of the most polluting in all industrial sectors, and membrane separation is the most promising technology for their treatment and reuse of auxiliary chemicals. This study evaluates the performance of three types of tubular ceramic ultrafiltration membranes differing by mean pore size (1, 2 and 500â
kDa) treating textile mercerization wastewater from a textile mill at different operating conditions cross-flow velocity (CFV) and temperature. Acceptable results were obtained with 1â
kDa ceramic membrane, with rejection efficiencies 92% for suspended solids, 98% for turbidity, 98% for color and 53% for total organic carbon at 20°C and 3â
mâ
s-1 CFV. Highest fouling effect was observed for 500â
kDa membrane and lowest CFV. According to the observed results, 1â
kDa membrane could be used for the treatment of wastewater from the textile mercerization process in terms of permeate quality.
