The spacer tube membrane module is designed for superior fluid dynamics in the most difficult applications. We use special open type feed spacers to minimize contact with the membrane surface, the ST module enables a high operation pressure but a low pressure drop across the vessel with a dramatically reduced fouling material between the spacer and membrane sheet.
RisingSun Membrane produces Spacer Tube Nanofiltration Membrane (STNF) for different High TSS Water.
* Salt seal installed on the end of the flow, low pressure side / permeate side.
** Stable flux, salt rejection based on the following test conditions: 30,000 mg/l MgSO4 , pressure 45bar,recycle rate 8%,temperature 20℃, pH=8. There will be a minor difference of permeate due to the feed quality.
1. Spacer tube nanofilter is high strength design, up to 80 bar operating pressure.
2. Open feed spacer with low flow resistance and concentration polarization.
3. Spiral wound structure with more membrane area.
4. Membrane is long using life.
5. Competitive price and fast delivery.
