A study on the PP hollow fiber membrane contactor and its performances for removing ammonia from wastewater or mixed gas: I. Removal and recovery of ammonia from wastewater

摘要

Recent research indicated that hydrophobic microporous hollow fiber membrane Contactor could be used to separate volatile contaminants from wastewater efficiently. The factors that influence the effect of separation of NH_3/H_2O are investigated carefully. It is found that the average diameter of micropore, porosity and gas penetration rate of polyprolylene (PP) hollow fiber membrane are maximized synchronously at draw elongation 260/100.
