DTRO Diaphragm Membrane

DTRO uses an open flow channel. The feed liquid enters the pressure vessel through the inlet. The treated liquid flows into the guide plate at a short distance, reverses 180 degrees from one side of the membrane to the other side of the membrane, enters the next guide plate, and then flows out from the outlet. This special design causes the liquid to form turbulence when it flows through the membrane surface and collides with the convex points on the guide plate surface, increasing the permeation rate and self-cleaning function, and extending the service life of the membrane.

■ DTRO Membrane Performance Parameters


■ DTRO Membrane Product Features
1.High-strength high-pressure resistant design
High-strength high-pressure resistant design, can withstand a maximum pressure of 200 bar.
2.Open flow channel
Open flow channel reduces flow resistance and concentration polarization.
3. When the high-pressure resistant high-rejection rate
Membrane is contaminated, part of the DTRO membrane and guide plate can be replaced according to the actual situation to reduce the system consumables cost.
