Behaviors of dissolved organic matter in membrane desalination The significance of dissolved organic matter (DOMs) in membrane fouling has been also increasingly noted in desalination plants using reverse osmosis (RO) and nanofiltration (NF). Nevertheless, little information is available on the interactions between DOM and other foulants such as inorganic scale Desalination 238 (2009)
Ultrasound, gravimetric, and SEM studies of inorganic fouling in spiral-wound membrane modules Ultrasonic time-domain reflectometry (UTDR) is combined with permeate-flux, gravimetric, and scanning electron microscopy (SEM) measurements for studying calcium-sulfate dihydrate fouling in a commercial spiralwound reverse osmosis membrane module. The UTDR amplitude response is shown to be more sen Desalination 208 (2007)
Scaling analysis of nanofiltration systems fed with saturated calcium sulfate solutions in the presence of carbonate ions 2 2 Nanofiltration of saturated calcium sulfate solution of 0.02 mol/L calcium content, with CO3 !/SO4 ! molar ratio !3 !4 2 ranging from 0.0500 to 2.8×10 was carried out in 6.5×10 m active membrane area laboratory module at 1.2×106 Pa transmembrane pressure using the total retentate recycle mode.
