Preparation of new composite membranes for water desalination using electrodialysis
The use of polyethersulfone (PES), an excellent but highly hydrophobic thermoplastic, as a matrix material for ionexchange membranes was investigated. To make PES ion-exchangeable, sulfonate groups were introduced to the polymer chains by sulfonation reaction with chlorosulfonic acid. The degree of sulfonation of sPES was estimated to be 21%. Preliminary experiments investigated the effect of p...
متن کاملModified polyether-sulfone membrane: a mini review
Polyethersulfone has been widely used as a promising material in medical applications and waste-treatment membranes since it provides excellent mechanical and thermal properties. Hydrophobicity of polyethersulfone is considered one main disadvantage of using this material because hydrophobic surface causes biofouling effects to the membrane which is always thought to be a serious limitation to ...
متن کاملAutomation of Ion Exchange Process Used for Desalination of Water
The problem for automation of an ion exchange process for desalination of water is considered. The paper describes first the process technology and the necessity to automate the process behaviour in order to achieve the needed quality of water with minimum consumption of resin and chemicals for regeneration. The instrumentation needed for measurement, data acquisition and control implementation...
متن کاملDesign of Anion Exchange Membranes and Electrodialysis Studies for Water Desalination
Anion exchange membranes are highly versatile and nowadays have many applications, ranging from water treatment to sensing materials. The preparation of anion exchange membranes (AEMs) from brominated poly(2,6-dimethyl-1,6-phenylene oxide) (BPPO) and methyl(diphenyl)phosphine (MDPP) for electrodialysis was performed. The physiochemical properties and electrochemical performance of fabricated me...
متن کاملElectrodialysis of Blood Using Ion-Exchange Membranes
THE correction of electrolyte imbalance and the removal of retention products of the blood during renal failure is at present achieved by the use of artificial kidneys which permit the diffusion of solutes through a semi-permeable membrane. Several types of apparatus used successfully for hemodialysis include those described by Kolff and Watschinger (1956) and Alwall, Norviit, and Steins (1948)...
