Description

Product Detail

Disctubular membrane technology referred to as DT membrane or RCDT membrane (Radial Channel Disc Tube membrane module) or PT membrane (Plate Tube membrane module) which is the most advanced products in DT membrane module technology.

RisingSun Membrane's Plate Tube membrane module is constructed from a series of octagonal membrane cushion separated by a series of plastic spacer Plates. The Plate support the membrane cushions but leaves an open channel flow path through module. The flow path is radial and gets reversed in 180°to flow over other side of cushion. This flow path repeats for each membrane in stack. The resultant turbulence due to reversal eliminates the concentration polarization minimizing scaling & fouling.

RisingSun Membrane's Plat Tube membranemodules have a lot of advantages in landfill leachate and high concentration of industrial wastewater. A flat sheet membrane as a membrane cushion stackswith completely open feed channels in combination with straight through feed flow.

High pressure vessel
Inlet and outlet pipe and accessories

DT Module Advantages:
1. High strength design, up to 75bar operating pressurewith high salt rejection.
2. We use an open channel feed flow path reduces the need for pretreatment and reduces the possibility of fouling.
3. The plate tube has a very short about only 3inchflow path between flow reversals.
4. The plate tube has minimal contact with membrane surface.
