  • Polymersomes-based high-performance reverse

    2018-6-1 · Polymersomes-based reverse osmosis (RO) membrane (PBM) for desalination was reported for the first time. An amphiphilic tri-block copolymer, PMOXA 6-PDMS 35-PMOXA 6 (ABA), was self-assembled to form polymersomes with spherical nanostructure. The polymersomes were then immobilized into a polyamide network via an interfacial polymerization reaction on top of polysulfone membrane …

  • Seawater Desalination RO Machine | Seawater Reverse ...

    Reverse osmosis is a widely utilised membrane technology for seawater desalination. The basic concept of Sea Water Reverse Osmosis (SWRO) is to utilise a semi-permeable membrane where most of the dissolved species are rejected while water permeates it. Normally, water spontaneously diffuses through a semi-permeable membrane from a dilute solution to a concentrated solution.
