Round DTRO Membrane Octagonal Plate Disc Tube Reverse Osmosis Module
The DTRO membrane cushions are sealed by ultrasonic welding. This welding technology has been proven over several years in different applications and with different membrane types.
The extremely short feed water path across the membrane followed by a 180 degree flow reversal eliminates polarization concentration.
Consequently, the PT Membrane-Module results in minimum membrane fouling and scaling. The permeate drains from the cushion's intermediate layer into the manifold with minimum flow path and minimum resistance.
