Research Progress of Brackish Water Desalination by Reverse Osmosis
Brackish water (BW) desalination is a primary path to relieve the shortage of water. As one of the BW desalination methods, reverse osmosis (RO) technology has advantage for both technology and process procedure. The expounding of this research studied or reviewed recent years, reverse osmosis membrane, energy recovery, new energy and application technology in BW desalination of RO at home and ...
متن کاملWater desalination using capacitive deionization with microporous carbon electrodes.
Capacitive deionization (CDI) is a water desalination technology in which salt ions are removed from brackish water by flowing through a spacer channel with porous electrodes on each side. Upon applying a voltage difference between the two electrodes, cations move to and are accumulated in electrostatic double layers inside the negatively charged cathode and the anions are removed by the positi...
متن کاملUsing Mesoporous Carbon Electrodes for Capacitive Deionization (CDI) of Salt and Brackish Water
Capacitive Deionization [2] (CDI [3]) is a water [4] purification process that offers promise in the deionization of salt and brackish water [4]. The process can create potable water [4] out of salt laden water [4] by using electric currents to separate the ions in the solution and attract them to cathode and anode plates. These plates act as filters, drawing salt and other ionized metals out o...
متن کاملSeawater Desalination by using Nanofiltration (NF) and Brackish Water Reverse Osmosis (BWRO) Membranes in Sequential Mode of Operation
In this study, the applicability of nanofiltration (NF) membranes as a pretreatment prior to reverse osmosis (RO) in seawater desalination was investigated. The membranes used wereNF270 and NF90 as the NF membranes, while the brackish water (BW) RO membrane BW30 was used as the RO membrane. In desalination tests, permeates of the NF membraneswere collected and used as the feed to th...
متن کاملNovel 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...
