Preparation and Characterization of seawater desalination reverse osmosis membrane support


100μm polyester (PET) non-woven fabric as substrate, polysulfone (PS) as solute, dimethyl formamide - (DMF) and dimethylacetamide (DMAC) For the coagulation bath, the support layer was prepared by immersion-precipitation phase inversion method and the desalination reverse osmosis membrane was prepared by the interfacial polymerization reaction.The structure of the support layer formed, pure water flux, specific surface area, pore volume, Average pore size, densification performance of desalinated reverse osmosis membrane, desalination rate and water flux before and after compaction were measured and characterized.


The results show that the support layer prepared by casting solution with PS as solute and DMF as solvent has good pressure-tightness and is suitable for the preparation of desalinated reverse osmosis membrane.
