Separation of dimethyl phenol using a spiral-wound RO membrane — Experimental and parameter estimation studies

Application of low-pressure reverse osmosis for effective recovery of bisphenol A from aqueous wastes

“…Nanofiltration and RO are among membrane technologies that have the ability of removing organic contaminants and EDCS [17,20,21]. By using RO for wastewater treatment, the pollutions are concentrated into small volume compared to the total waste volume [22]. Other advantages of RO process are energy consumption reduction, simple design and easy to operate [23,24] in comparison with traditional processes.…”

“…It have been reported that the efficiency as well as the mechanism of rejection of organic solutes by membranes are influenced by various parameters such as pressure, feed solution composition, flow rate, membrane-solute interactions and solute, and membrane properties [17,22,28].…”

Response Surface Methodology Modeling Correlation of Polymer Composite Carbon Nanotubes/Chitosan Nanofiltration Membranes for Water Desalination

“…3−5 This technology has also been widely employed for many years for the desalination of the largely available water resources, such as saline and marine water. 6 Reverse osmosis (RO) and nanofiltration (NF) techniques have extensively been used to desalinate brackish water. 7 For instance, selected ultrathin barrier layers are underpinned by many robust, porous polymeric support layers in traditional NF and RO membrane systems to improve their salt rejection capabilities.…”

Performance evaluation of multi-stage reverse osmosis process with permeate and retentate recycling strategy for the removal of chlorophenol from wastewater

“…Several successful mathematical models were developed to describe the removal of phenol and phenolic compounds from wastewater using a single spiral wound RO process and focused on the impact of operating parameters on the whole performance and optimising the removal of chlorophenol using genetic algorithm (Srinivasan et al, 2009;Sundaramoorthy et al, 2011b;Srinivasan et al, 2010;Srinivasan et al, 2011;Al-Obaidi and Mujtaba, 2016;Al-Obaidi et al, 2017a;Al-Obaidi et al, 2017b;Al-Obaidi et al, 2017c). However, multi-stage RO wastewater system considering the permeate and retentate recycling scheme for the removal of phenol and phenolic compounds from wastewater has not been investigated yet.…”
