Submerged membrane distillation for inland desalination applications Submerged vacuum membrane distillation is an alternative to conventional membrane distillation conﬁgurations which offers lower energy consumption and higher thermal efﬁciency. The feasibility of a submerged vacuum membrane distillation system for inland desalination was investigated. Relatively sim Desalination 361 (2015)
Direct contact membrane distillation: Capability to treat hyper-saline solution In this paper, we focused our work on the direct contact membrane distillation (DCMD) capability to treat hypersaline solution. The governing operative model for mass transfer was investigated. The measured ﬂux has been well predicted by the Knudsen-molecular mechanism model. The effects on the DCMD Desalination 376 (2015)
Nanofiltration as energy-efficient solution for sulfate waste in vacuum salt production In vacuum salt production sulfate is an important impurity, but it is also used to remove other cationic impurities from the raw brine. Removal of excess sulfate is currently done by purging salt crystallizer mother liquor from the brine plant, or crystallizing sodium sulfate through evaporative or Desalination 246 (2009)
Polyamide-based composite membranes: Part 2. Interaction, crystallization and morphology In this work, the interaction, crystallization and morphology of membranes derived from polyamides/poly (vinylalcohol) (PA/PVA, PA: PA66, PA69, PA610 and PA612) blend materials are studied at various weight fractions and various crystallization temperatures. The experimental work includes differenti Desalination 227 (2008)
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. P Desalination 159 (2003)
Untitled The influence of process conditions such as feed rate, calcium/carbonate ratio, pH, complexing agents [ethylenediaminetetraacetic acid (EDTA), citrate (CIT)] and their concentration on the average particle size and shape of precipitated calcium carbonate was studied. The precipitation was performed Desalination 159 (2003)
Developments in high recovery brackish water desalination plants as part of the solution to water quantity problems This paper reviews three ways in which existing brackish water reverse osmosis (BWRO) desalination plants can be modified to increase overall water recovery from the 70–75% range to the 90–95% range. The three techniques used to increase plant recovery are: (i) seawater reverse osmosis (SWRO) for wa Desalination 153 (2002)
