Graft Copolymerized Cellulose Acetate Membrane for Desalination by Reverse Osmosis

Novel Membrane Materials for Reverse Osmosis Desalination

The use of solvents in desalination processes limits the use of certain materials in the construction of the reverse osmosis membranes. Therefore now the research effort has focused on improving new materials. In particular, nanostructured materials will probably form the basis for new reverse osmosis membrane materials. This study makes a review of the new materials used for the construction o...

Membrane Modeling for Simulation and Control of Reverse Osmosis in Desalination Plants

A mathematical model of Reverse Osmosis membranes is proposed for use in the testing and comparison of control strategies in Reverse Osmosis plants. The model has been developed so that it can be used within off-the-shelf software and the parameters are simple to obtain from available plant measurements. Some simulations of the proposed model show that it correctly reproduces the expected proce...

Mineral scale monitoring for reverse osmosis desalination via real-time membrane surface image analysis

Pebax-Modified Cellulose Acetate Membrane for CO2/N2 Separation

Carbon dioxide (CO2) release from the exhaust gas streams of power plants that burn fossil fuels contributes the most emission of this gas, which includes more than half of the greenhouse effects. Thus, the separation of CO2 from exhaust gases is one of the main environmental concerns. Membrane technology, due to many advantages, has attracted many research attentions among the various gas sepa...
