| Summary, etc. | This work is a continuity of the ongoing study of sweeping air pervaporation or air perstripping for the treatment of VOCs found in numerous industrial wastewater. A thorough literature survey on different models, influencing parameters, membranes, modules and module geometries was performed in order to investigate the results of the experiments in the light of the latest concepts. In order to study the behavior of pervaporation and its underlying kinetics, laboratory scale experiments were performed, with dense silicone-polyethersulfone, commercial composite capillary membranes. Basically optimization of flux with respect to the air flow rate, responses to different initial feed concentration of VOCs, performance of different flow modes ( cocurrent and cross flow) and the effect of presence of an additional interfering compound (1, 1, 1 trichloroethane) on the flux of a targeted volatile organic compound (trichloroethylene) were the focus of the study. Optimization of flux with respect to air flow rate could be clearly identified and the effect of excess air flow on flux production was found to have either no impact or negative impact, depending upon the flow mode chosen. Out of the parameters that vitally influence flux production, initial feed concentration was found to be one of predominant one and it was found that the membrane strains to handle low feed concentration of the VOCs. Water flux was found to be heavily influenced by organic flux and decreased with the increase of the organic flux. Cross flow mode was found to be better than the cocurrent flow mode in almost all respects. However the difference was marked in case of low concentration of organic compounds which is the usual case with actual wastewater. Also at higher air flow rates the performance of the cross flow mode improved unlike cocurrent flow mode. The effect of the addition of another organic compound of almost same nature, was found to be positive and flux of both the compounds improved due to the better swelling of the membrane. Prediction of flux by Solution-Diffusion model was reasonably good, while Resistance-in-Series model showed that for VOCs, resistance at the liquid-membrane interface was the rate limiting step. Models for binary compounds failed to predict flux upto expectations and indicated that modifications are required. Lastly perstripping combined with the state-of-art post treatment technologies has been proposed to complete the treatment train of VOCs. |
