Product Description

Spiral Wound RO/NF Membrane Module (STRO/STNF) 120bar Max Operation Pressure

RisingSun Membrane's Spacer Tube (ST) Module can be used for sea water desalination and waste water treatment. We can offer either reverse osmosis or nanofiltration membrane sheet in order to deal with different kinds of waste water.  
Special Membrane Feed Spacer
Spiral Wound RO/NF Membrane Module (STRO/STNF) 120bar Max Operation Pressure
We use a very special ladder type feed spacer, which only come into marginal contact with their neighbouring membrane sheet. In this way, the spacers are able to minimise the resistance that is exerted on the feed flow.
This special design also greatly reduces the build up of fouling materials compared with common element.

Color Instruction
Green: Feed Wate
Blue: Permeate
Red: Seals and O-rings


On this ST module the feed is from the top.

The feed water is diffused by the top seal plate to send the feed water evenly around the top of the membrane element.

The feed water flows down through the membrane element, as it does pure water permeates and flows out thourgh centre collection device into the space around the tie rod and flows down to the permeates outlets.

The concentrated feed water is channelled by the bottom seal plate to the bottom HP connection and out of the module.
 
Features
1. Spacer tube (ST) module is high strength design, up to 120 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.
6. Cross replacements: Nanostone (Rochem).

** RO3 test condition: 2,000mg/l NaCl solution at 15.5bar applied pressure, 15% recovery, 25ºC; RO5 test condition: 32,000mg/l NaCl solution at 55bar applied pressure, 8% recovery, 25ºC; NF2 test condition: 2,000mg/l MgSO4 solution at 7bar, 15% recovery, 25 ºC. There may have about ±15% change for individual module flow rate.
Performance specifications shown above are nominal values. Individual module permeate flow rate may vary based on inlet water condition. 
Note: We could offer any membrane sheet to make ST membrane module, for example, STRO4-8035, STRO5-8035, STRO1-8042, STNF1-8042, etc.
