Membrane

All membranes we use, are manufactured in our own production facility. 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.).

Aside from various reverse osmosis membranes, we also offer nanofiltration membranes as well.

Membrane cushion types for disc tube technology (RCDT module) in two diffrent shapes:

Round type (SW,BW)
Octagonal type (SW,BW)

Membrane Cushion: Round type

	BW 30	SW 30
Material:	Polyamide TFC	Polyamide TFC
Type:	Round	Round
Outer diameter:	185 mm +/- 2 mm	185 mm +/- 2 mm
Inner diameter:	44 mm +/- 2 mm	44 mm +/- 2 mm
Nominal NaCl rejection at 25°C:	99,2%	99,6%
Salt rejection range in waste water: *	95,0% – 99,0%	97,5% – 99,5%

*:Depending on following factors: Waste water characteristic, Temperature, Recovery rate, Operating pressure, Feed flow.
