Chlorine-Resistance of Reverse Osmosis (RO) Polyamide Membranes
Progress in Polymer Science, 2017Abstract Polyamide (PA) reverse osmosis (RO) membranes suffer performance decay when exposed to oxidizing species, limiting their lifetime and increasing operation costs. This article aims at reviewing the effect of chlorine species on the performance and characteristics of PA-membranes. Experimental evidence supporting different competing mechanisms

Comparison of Fouling Behavior in Forward Osmosis (FO) and Reverse Osmosis (RO)
Journal of Membrane Science, 2010Abstract Fouling behaviors during forward osmosis (FO) and reverse osmosis (RO) are compared. Alginate, humic acid, and bovine serum albumin (BSA) are used as model organic foulants, and two suspensions of silica colloids of different sizes are chosen as model particulate foulants.

Hydraulic Energy Generation for RO (Reverse Osmosis) from PRO (Pressure Retarded Osmosis)
2020 4th International Conference on Green Energy and Applications (ICGEA), 2020 Although reverse osmosis (RO) is currently the most energy efficient, widely used, desalination technology, it still requires a great deal of energy to create the high pressure necessary to overcome the osmotic pressure of seawater. Pressure retarded osmosis (PRO), on the other hand, utilizes the salinity gradient between two solutions of different ...

Mathematical and experimental modeling of reverse osmosis (RO) process
Korean Journal of Chemical Engineering, 2021This paper provides a mathematical simulation model for the reverse osmosis (RO) process with series elements. A mathematical simulation model was developed based on the mass, material and energy balances considering the concentration polarization. The simulation model is open-source and easy to couple with other computational tools like optimization ...

The Outlook for Forward Osmosis-Reverse Osmosis (FO-RO) Hybrid Desalination Market
Journal of the Korean Society of Water and Wastewater, 2016Seawater desalination market after global economic crisis has been stalled due to the market uncertainties and decreased demand in desalination. It is important to review the status of the market and to estimate the appropriate share of Forward osmosis-Reverse Osmosis (FO-RO) hybrid desalination technology by figuring out the outlook of the ...

The development of the spiral-wound reverse osmosis(RO) modules
Desalination, 1985Abstract The four-inch diameter spiral-wound RO membrane elements have been developed succesfully. The membrane element (type-SRC-401) is 965 millimeter long. A demonstrating prototype, designated SRO-80-1000, has been designed and fabricated by using the type-SRC-401 spiral-wound membrane elements.

Inorganic Fouling Mitigation by Salinity Cycling in Batch Reverse Osmosis
Water Research, 2018 Enhanced fouling resistance has been observed in recent variants of reverse osmosis (RO) desalination which use time-varying batch or semi-batch processes, such as closed-circuit RO (CCRO) and pulse flow RO (PFRO).

Fouling and Cleaning Characteristics of Reverse Osmosis (RO) Membranes
Journal of Chemical Engineering & Process Technology, 2015This work deals with fouling and successive cleaning of RO membrane fouled by an organic foulant, sodium alginate using a laboratory-scale cross flow test unit. First, spiral-wound RO membrane was fouled with sodium alginate solution up to 10% and 15%, respectively at an applied pressure of 1380 kPa with flow rate of 10 lit/min.
