Abstract:
Pervaporation (PV) is a cost-efficient separation process successfully used in the dehydration of organic solutions, which is also regarded as a promising concentrating and desalination technology. However, the performance of water reclamation by PV from real high-strength wastewater is still lacking. In this study, the feasibility of reclaiming water from real leachate reverse osmosis concentrate was investigated with both laboratory and pilot-scale apparatus. With a feed temperature set to 70 ℃, the laboratory-scale setup achieved a water flux of 17.4 LMH, while the pilot-scale system obtained 8.9 LMH with flat membrane modules. Increasing the feed temperature from 70 to 85 ℃ resulted in a minimal enhancement of water flux, whereas a linear increase in water flux was observed as osmotic side pressure decreased. Results showed high salt rejection (> 99.8%) and COD removal efficiency (94.6%) under all operating conditions, and the reclaimed water could meet the quality requirements for reuse.
