Desalination, 2014
Abstract The combination of Forward Osmosis (FO) and Reverse Osmosis (RO) was evaluated for seawater desalination. RO process was suggested for the draw solution regeneration because of its high efficiency and applicability for a wide range of ionic solution treatments. Two different salts, NaCl and MgCl2, were used as a draw solution.

Concentration of antibiotics by reverse osmosis
Biotechnology and Bioengineering, 1977AbstractReverse osmosis is shown to be a viable process for the concentration of highly labile antibiotic solutions. Mathematical n10deJs of antibiotic inactivation by chemical and biological contamination are proposed and correlated with experimental data. Procedures for obtaining high antibiotic recoveries are discussed.

Reverse osmosis (RO) desalination is a method of producing fresh water from seawater by a process similar to filtration, rather than by traditional evaporative distillation. A semipermeable membrane allows water molecules to pass through while blocking the passage of most other ions.

Rotating reverse osmosis and spiral wound reverse osmosis filtration: A comparison
Journal of Membrane Science, 2006Wastewater produced by the crew members on a long-term space mission needs to be recovered as potable water. Reverse osmosis (RO) has long been in use as a physical membrane separation technology for wastewater treatment. However, membrane fouling and concentration polarization have limited the efficiency for high recovery reverse osmosis systems.

Desalination by Reverse Osmosis
2017This chapter deals with the main techno-economic and environmental issues involved in assessing the sustainability of RO membrane technology for water desalination. The technical and economic aspects of desalination plant design and operation are reviewed, focusing on the key parameters of specific energy consumption (SEC) and product water unit cost ...

Reverse osmosis in seawater concentration
Desalination, 1983Abstract Reverse osmosis as the first step in the process of seawater concentration has been investigated. The brine of up to 10 % TDS was aimed at applying pressures not higher than 60 bars. Such a process was shown to be feasible when reverse osmosis membranes of moderate solute rejections were used.

An empirical modeling method has been suggested for the reverse osmosis process. Least-square fitting of data to a third-order’ polynomial has resulted in the accurate modeling of Du Pont’s hollow fiber B-10 module for water desalination. The general modeling methodology is not specific to this system but can readily be used to model other available ...

Reverse Osmosis and Ultrafiltration
1980Economic comparisons indicate reverse osmosis to be more cost effective than distillation for large operations [1]. Important progress has been made in synthetic semipermeable membranes, leading to a wider scope of reverse osmosis applications, including the purification of used water and saline water for drinking, the supply of ultra-pure water for ...
