Reverse Osmosis (RO) is a form of desalination in which salt is filtered out by means of special membranes, producing potable water immediately.
Typical process steps in an RO system:
1. Pre-treatment (protecting the RO membranes)
2. High Pressure Pumps
3. Energy Recovery system
4. RO Membrane Modules
5. Concentrate discharge
6. Post-treatment (remineralisation, disinfection)
Salient Features of the RO process:
-
- A cold process utilizing pressure energy for desalination.
- The most cost-effective desalination process for standalone desalination.
- Commercially competitive for plants of all sizes and most applications.
- A matured technology well-tried and tested with a continued increase in market share.
- Requires a well-designed pretreatment system for success
- Developments in high energy recovery devices and low pressure membranes have made this process very competitive with low power requirements.
- Quick start-up and shutdown are possible
- Modular design enables easier and quicker addition of capacities.
