Product Description
Vontron ULP21-4040 Ultra Low Pressure RO Membrane for Reverse Osmosis Systems
A highly efficient semi-permeable RO membrane that removes over 99.5% of salts, contaminants, and impurities through pressurized filtration, delivering pure water for desalination, industrial processes, and potable use.
Brief Introduction
ULP series (ultra low pressure) aromatic polyamide RO element is developed by VONTRON for treatment of surface water and underground water. Its operation pressure is about 2/3 of low pressure membrane, and the rejection rate can reach 99.5%. This reduces the investment cost of related pumps, pipelines, containers and other equipment, as well as the operation cost of RO system, improving economic benefits.
Scope of Application
ULP series RO element is suitable for treatment of surface water, underground water and municipal water with TDS less than 2000 ppm. It is mainly applied in:
- Bottled water production
- Drinking water systems
- Boiler replenishment water
- Food processing
- Pharmaceutical manufacturing
- Other industrial applications
