Carbon molecular sieve membranes (CMSMs) are inorganic produced by carbonization of a thermosetting polymer. The selection the adequate polymer, conditions and post-carbonization treatment allow production large variety porous structures. mass transport species through these structures is not easy to model in detail. This review reports last developments field CMSMs. membrane also briefly touch...

Inorganic fouling is one of the critical operational issues in reverse osmosis membrane. Few researches investigated effects of membrane surface characteristics on inorganic fouling and on anti-scaling techniques although the fouling occurs on the membrane surface. The objective of this paper was to examine whether different characteristics of deposition of calcium carbonate solids would occur ...

Mismanagement, pollution and excessive use have depleted the world’s water resources, producing a shortage that in some territories is extreme. In this context, need for potable prompts development of new more efficient wastewater treatment systems to overcome shortages by recovering reusing contaminated water. Among methods, membrane technology considered one most promising. Besides, photocata...

During interfacial polymerization (IP) reaction between m-phenylenediamine (MPDA) and trimesoyl chloride (TMC), a by-product, i.e. hydrochloric acid can produce. This produced acid diffuses back in aqueous phase and protonates MPDA and reduces its reactivity that results in lowering of polymer yield and performance of membrane. Further, for getting consistency in reverse...
