- Low-Pressure Spiral RO Membrane Element NTR-759HR
Low-Pressure Spiral RO Membrane Element
NTR-759HR
Excellent NaCl Rejection Performance and High Water Permeability Flow at Low Pressure Operation.
Outline
NTR-759HR demonstrates a high separation performance under lower operating pressure compared to conventional cellulose acetate reverse osmosis membrane elements. The NaCl rejection rate is over 99%, and the performance of low molecular weight organic compound rejection is also very high .
Features
- At low pressure operations of less than 1.5MPa, this model attains a comparable or higher water permeate flow than conventional mid-pressure reverse osmosis membranes operating at 3.0Mpa.
- With the adoption of a composite membrane comprising an ultra-thin fully aromatic polyamide membrane on a polysulfone support layer, excellent NaCl rejection performance is exhibited at low pressure operation.
- High energy efficiency and low operating costs are achieved with its high performance at low pressure operation.
Applications
NTR-759HR is available for:
- Primary pure water systems, sub-systems, and recovery systems of ultrapure water systems it is used in the semiconductor industry.
- Concentration processes, NaCl rejection, or recovery of valuable components from waste water it is used in the food industry.
- Recovery of valuable resources it is used in various industries.
