A Novel Approach Toward Fabrication of High Performance Thin Film Composite Polyamide Membranes.
A practical method is reported to enhance water permeability of thin film composite (TFC) polyamide (PA) membranes by decreasing the thickness of the selective PA layer. The composite membranes were prepared by interfacial polymerization (IP) reaction between meta-phenylene diamine (MPD)-aqueous and trimesoyl chloride (TMC)-organic solvents at the surface of polyethersulfone (PES) microporous s...
متن کاملHigh performance thin-film composite forward osmosis membrane.
Recent studies show that osmotically driven membrane processes may be a viable technology for desalination, water and wastewater treatment, and power generation. However, the absence of a membrane designed for such processes is a significant obstacle hindering further advancements of this technology. This work presents the development of a high performance thin-film composite membrane for forwa...
متن کاملPerformance and Structure of Thin Film Composite Reverse Osmosis Membranes Prepared by Interfacial Polymerization in the Presence of Acid Acceptor
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...
متن کاملAnionic/Non-ionic Surfactants in Aqueous Phase of Thin Film Composite Poly(Paraphenylene Terephthalamide) Nanofiltration Membranes
In this work, the Interfacial interfacial polymerization (IP) technique was employed using terephthaloyl chloride (TPC) and p-phenylenediamine (PPD), as reactant monomers, to prepare poly(paraphenylene terephthalamide) thin film composite (TFC) nanofiltration on polyethersulphone (PES) support layer. The effects of six different anionic and non-ionic surfactants, in the aqueous phase on the mor...
متن کاملPreparation of Novel Thin-Film Composite Nanofiltration Membranes for Separation of Amoxicillin
Several novel composite membranes were prepared to separate and recycle amoxicillin from pharmaceutical wastewater via nanofiltration process. The synthesis of these membranes included three stages: 1- preparation of polysulfone ultrafiltration membranes as a support via phase separation process, 2- modification of its surface by interfacial polymerization as a selective layer (polyamide), and ...
