Description
Vontron reverse osmosis membrane FR11-4040 utilizes specialized manufacture technique that can improve the hydrophilicity, electric charge and roughness of its surface, thus reducing the breeding and adsorption of pollutants and microbes on membrane surface. Pure water production from surface water, for example: lake water, river water, etc. Desalination of Reclaimed water, for example: Reclaimed water, industrial wastewater, RO concentrated water, etc.
- Operating pressure: 225 psi (1.55 MPa)
- Operating Temperature: 25℃
- Minimum salt rejection: 99.3%
