Product Description
RisingSun Membrane's Disc. Tube membrane module includes RO and NF by using different kinds of membrane sheet. The membrane module structure is completed distinct from the traditional spiral wound membrane. With open flow channels, feed flows through the entrance into the pressure vessel and reach the disc in a short distance. Then the feed flows 180 degrees from one side of the membrane reverse flow into the other side of the membrane, into the next disc again and finally runoff from outlet.

3. Cross reference: Rotreat RCDT module
A typical process diagram:
75bar High pressure membrane module specification:
** RO3 test condition: 2,000mg/l NaCl solution at 15.5bar applied pressure, 25ºC; RO5 test condition: 32,000mg/l NaCl solution at 55bar applied pressure, 25ºC; NF2 test condition: 2,000mg/l MgSO4 solution at 7bar, 25ºC. Permeate flux and stable rejection may vary based on inlet water condition. There may have about ±20% change for individual module permeate flux.
