Low pressure multi-stage RO system developed in “Mega-ton WaterSystem” for large-scaled SWRO plant A new RO system for large-scaled SWRO plant has been developed in the project named “Mega-ton Water System” with private–public cooperation in Japan. The characteristic of the newly developed RO system to increase the recovery rate is to use the short vessel that contains 2–4 elements for the ﬁrst s Desalination 368 (2015)
Improvement of overall water recovery by increasing RNF with recirculation in a NF–RO integrated membrane process for seawater desalination This study explored the effect of increasing nanoﬁltration (NF) permeate recovery (RNF) by recirculation and dosage of chemicals on NF separation performance, concentration polarization (CP) and accumulation of scalingprone ion concentration on NF membrane surface. The related coupling effect on sea Desalination 361 (2015)
Concentration polarization model of spiral-wound membrane modules with application to batch-mode RO desalination of brackish water Article history: Received 8 July 2014 Received in revised form 23 December 2014 Accepted 24 December 2014 Available online 22 January 2015 For inland applications, batch-RO desalination has shown advantages in BW desalination over conventional continuous BWRO because of the high recovery ratio achie Desalination 368 (2015)
Treatment of model inland brackish groundwater reverse osmosis concentrate with electrodialysis — Part III: Sensitivity to composition and hydraulic recovery − Electrodialysis has an advantage in concentrate treatment because the waste concentration factor increases linearly with removal ratio, Sodium concentration (mg/L) Calcium concentration (mg/L) Chloride concentration (mg/L) resistance of 2 Ω·cm2, the resistance from two membranes would represent 14 Desalination 347 (2014)
High recovery brackish water desalination process devoid of precipitation chemicals The present paper describes pilot plant development of a novel process enabling increase of water recovery in brackish water desalination without using any chemicals. This is achieved by precipitating the scaling salts of a carbonate-rich concentrate by increasing the pH through air stripping of CO2 Desalination 283 (2011)
Application of energy efficient reverse osmosis system for seawater desalination A performance of an energy-efficient reverse osmosis (RO) system for seawater desalination was evaluated. The evaluation focused on energy saving performance of the RO system. The strategy adopted was to induce high recovery (50%) through the pressure increase. For this purpose, a pilot-scale RO pla Desalination 144 (2002)
Modelling of a low-pressure reverse osmosis system with concentrate recirculation to obtain high recovery levels A big problem for the desalination plants situated far from the sea is the elimination of the concentrated brines. The volume reduction of the final concentrate could allow an economic transport and a high recovery level. In order to solve this problem, a reverse osmosis system with recirculation (R Desalination 144 (2002)
