Reuse of Reverse Osmosis Membranes - Case Study: Tajoura Reverse Osmosis Desalination Plant [PDF]

open access: yesIranica Journal of Energy and Environment, 2019
Libya is currently experiencing a major challenge in water supply due to reduction in the groundwater, especially around the coastal region. This problem is likely to create challenges for drinking water supply and the agricultural sector.

The benefits of hybridising electrodialysis with reverse osmosis [PDF]

open access: yes, 2014
A cost analysis reveals that hybridisation of electrodialysis with reverse osmosis is only justified if the cost of water from the reverse osmosis unit is less than 40% of that from a stand-alone electrodialysis system.

Evaluation of a new air water generator based on absorption and reverse osmosis

open access: yesHeliyon, 2020
The evaluation of a new air water generator (AWG) based on absorption and reverse osmosis is described. For the evaluation, an aqueous lithium bromide solution has been selected from a wide range of liquids as the absorbent.

The concentrating of alizarin using a reverse osmosis process [PDF]

open access: yesJournal of the Serbian Chemical Society, 2005
Membrane technologies in general and reverse osmosis in particular have been employed for the concentrating of solutions. In this study, the concentrating of a heat sensitive alizarin extracted from madder root was realized using an FT30 reverse osmosis ...

On the asymptotic flux of ultrapermeable seawater reverse osmosis membranes due to concentration polarisation [PDF]

open access: yes, 2016
Just as thermodynamic considerations impose a finite limit on the energy requirements of reverse osmosis, concentration polarisation imposes a finite limit on flux, or equivalently, on system size.

Optimization of a Water Purification System in Real Time

open access: yesChemical Engineering Transactions, 2015
This work considers the problem of the optimal control of a water treatment plant. It examines the existing mathematical models of reverse osmosis membranes and the need for developing own mathematical model of these elements.
