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...
متن کاملSustainable Seawater Reverse Osmosis Desalination as Green Desalination in the 21st Century
Seawater reverse osmosis desalination (SWRO) requires less energy compared with the distillation method and thus is an important technology except Middle Eastern countries whereenergy costs are higher. Recently, even Middle Eastern countries where the distillation method is still a major technology, have begun adopting the RO method in new desalinationplants in line with government ...
متن کاملReverse Osmosis Pretreatment: Removal of Iron in Groundwater Desalination Plant in Shupramant-Giza - A Case Study
Reverse osmosis (RO) is being increasingly utilized throughout the world for desalination due to the latest improvements in RO membrane performance and its reduced cost compared to thermal desalination. In this paper, Different media and chemicals have been used for Iron removal to prevent membrane fouling of groundwater reverse osmosis plant located in Shupramant-Giza. The objective is to pres...
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 کاملRemoval of dissolved organic matter by granular-activated carbon adsorption as a pretreatment to reverse osmosis of membrane bioreactor effluents.
The adsorption of dissolved organic matter (DOM) on granular-activated carbon (GAC) as a pretreatment to reverse osmosis (RO) desalination of membrane bioreactor (MBR) effluents was studied in lab- and pilot-scale columns. The pattern and efficiency of DOM adsorption and fate of the hydrophobic (HPO), transphilic (TPI) and hydrophilic (HPI) fractions were characterized, as well as their impact ...
