摘要:
Three different thickness isotactic polypropylene (iPP) hollow fiber membranes were prepared for air gap membrane distillation (AGMD) via thermally induced phase separation (TIPS) with cosolvent di-n-butyl phthalate and dioctyl phthalate. A study was carried out to investigate the effect of membrane thickness on the water flux and mechanical properties of the membranes. The ratio of membrane thickness to membrane inner diameter was constant at 0.2. Three relevant AGMD modules were fabricated. During AGMD of 6 wt% salt solution, the influence of inlet temperature of cold brine feed (T
