Advanced water treatment equipments for desalination - Water and Wastewater - Drinking Water
Areas that have no or limited surface water or groundwater may choose to desalinate seawater or brackish water to obtain drinking water. Reverse osmosis is the most common method of desalination, Sea Water Reverse Osmosis (SWRO) is a reverse osmosis desalination membrane process that has been commercially used since the early 1970s. Because no heating or phase changes are needed, energy requirements are low in comparison to other processes of desalination, though still much higher than other forms of water supply (including reverse osmosis treatment of wastewater).
The typical single pass SWRO system consists of the following components:
- High-pressure pump
- Membrane assembly
- Remineralization and pH adjustment
