MEMBRANE
Membrane types, shapes and flow geometrie
All membranes we use, are manufactured in our own membrane production. This way we can guarantee the highest quality standard and a very short delivery time.
The membrane cushions are made of two single membrane discs with an intermediate layer (spacer). The membranes are manufactured from modified palyamide, the material of intermediate layer is polyester. Using the ultrasonic welding technique the medium can not come into contact with other materials (membrane glues, etc.).
Membrane types
There are 2 types of membranes what can be manuactured to fit into the RCDT module:
- nano-filtration
- reverse osmosis
Membrane shapes
Membrane cushion types for disc tube technology (RCDT module) in two membrane shapes:
Radial Channel Disc Tube module disc with octagonal membrane cushion
Flow geometrie
Disc tube module is using a cross-flow geometry, and is consists a pressure tube and hydraulic discs, witch are held by a central tension rod, and membrane cushions whom lies between two discs.
Spiral wound module is using a
Cross flow of the radial channel disc tube module
Advantage of cross flow:
