The aim of the study was to compare the removal efficiency of anionic surfactant (belonging to alkylbenzenesulfonate family) from water solutions by means of ultrafiltration and ion-exchange. During the first stage of the experiments, the influence of surfactant type and its concentration, membrane

Taking into account the presented results, it can be stated that ultrafiltration — low pressure membrane process — is suitable for concentration of highly polluted effluents containing detergents. The high separation efficiency of anionic surfactant from model solutions as well as from detergent was

A low-pressure membrane process was studied in order to treat aqueous solutions containing both dye and surfactant. The influence of various textile dyes (methyl orange, indigo carmine, amido black, titan yellow or direct black) on separation efficiency of surfactants (sodium dodecyl sulphate, SDS)

Ultrafiltration separation of an anionic surface active agent belonging to the alkylsulfonate family was studied. Asymmetric membranes made of polyethersulfone, polysulfone, regenerated cellulose, cellulose acetate and polyamide with a molecular weight cut-off equal to 5, 10 and 30 kDa were used. Th

The objective of this study was to investigate the influence of MWCO, pressure, SDS concentration, salt amount and temperature on surfactant removal and permeate flux. Intersep Nadir membranes made from polyethersulphone (PES) and polysulphone (PS) were used. With the addition of a mineral salt to t
