Low-Pressure Spiral RO Membrane Element
NTR-729HF
High Water Permeability Flow at Ultra-low Pressure.
Outline
NTR-729HR demonstrates high separation performance at lower operating pressures compared to conventional cellulose acetate reverse osmosis membrane elements. The NaCl rejection is over 90%, and the performance of low molecular weight organic compound rejection is also very high.
Features
- A low pressure RO element which uses a synthetic high polymer composite membrane (PVA), realizing over 90% NaCl rejection rate at high water permeate flow.
- The synthetic high polymer reverse osmosis membrane deals with bacterial attacks.
- High removal performance and water permeate flow at low pressure operations under 1MPa. Also exhibits superior removal performance of organic compounds (valuable components and TOC).
Applications
NTR-729HF is available for:
- Ultrapure water systems for semiconductors
- Desalination of river water and brine water
- Concentration and refining for bulk pharmaceuticals
- Desalination in advanced sewage treatment
