Mass transport coefficients of different nanofiltratıon membranes for biologically pre-treated textile wastewaters

► The lab-scale membrane system studies on biologically pre-treated textile wastewaters. ► NF membranes (NP010 and NP030) were studied at different pressures (4, 6, 8 and 10 bar). ► The Bs (mass transfer coefficient) and Rs (overall removal rate) values are obtained. ► Nernst-Planck equation was determined to be compatible. ► NP030 membrane was very feasible for both wastewaters.
