The present study demonstrates the applicability of hollow fiber membrane contactors (HFMC) containing the hydrophobic polypropylene- (PP-) microporous hollow fibers for the removal of dissolved hydrogen sulfide (H2S) from wastewater. The tests were conducted on a fabricated and assembled laboratory-scale experimental set-up equipped with an HFMC module operated under liquid-liquid extraction (LLE) mode. The synthetic wastewater feed contained different H2S concentrations in the range between 300 and 1600 ppm and aqueous monoethanolamine (MEA) was used as the extract phase. The HFMC system was shown to be effective in the treatment of H2S-laden wastewater, having more than 98% removal efficiency. Mathematical analysis was carried out explaining the experimental results. The model analysis was based on pore diffusion in the membrane,. and also, the adsorption/desorption rate of H2S at the pore walls. The slope of the adsorption isotherm for H2S on the PP-surface was utilized as the model adjustable parameter. The model predictions and the data were found to be in reasonably good agreement, with the slope of the isotherm found within the same order of magnitude as described in the literature for different common water-dissolved gases on the various polymeric surfaces.
