Removal of surfactants by powered activated carbon and microfiltration. Basar, C., A., Karagunduz, A., Cakici, A., & Keskinler, B. WATER RESEARCH, 38(8):2117-2124, 2004. abstract bibtex Direct and indirect releases of large quantities of surfactants to the
environment may result in serious health and environmental problems.
Therefore, surfactants should be removed from water before release to
the environment or delivery for public use. Using powdered activated
carbon (PAC) as adsorbent and separating particles with a membrane may
be an effective technique to remove surfactants. In this study, the
removal of surfactants by microfiltration and PAC was investigated and
the influences of the operating parameters on the effectiveness on
microfiltration were determined. An anionic (LABS) and a cationic
surfactant (CTAB) were selected for the experiments. A series of batch
experiments were performed to determine the sorption isotherms of
surfactants to PAC. Then microfiltration experiments were carried out.
The results showed that formation of secondary membrane on the surface
and, within the pores of the membrane, increased the retention of
surfactants significantly. Increase in transmembrane pressure and pore
size of the membrane decreased the rejection rates, but increase in
cross-flow velocity increased the rejection rate. Temperature had no
apparent affect on the efficiency of surfactant removal. Presence of
electrolyte had different effects on CTAB and LABS. The rejection rates
of CTAB significantly increased when the concentration of NaCl
increased; however, a slight decrease was observed in the rejection
rate of LABS at the same conditions. (C) 2004 Elsevier Ltd. All rights
