1. Disc tube membrane technology is referred to as DT, commonly known as disc tube reverse osmosis (DTRO) and disc tube nanofiltration (DTNF), and its membrane component structure is completely different from the traditional roll membrane. DT adopts an open flow channel, the material wave enters the pressure vessel through the entrance, the treated liquid flows into the deflector disc at a short distance, flows 180 degrees from one side of the film into the other side of the film, and then enters the next deflector disc and flows out from the outlet. This special design allows the liquid flowing through the surface of the film to form a flow when it collides with the convex point of the plate, increasing the transmission rate and self-cleaning function, and extending the service life of the film.
Uniqueness:
1. High strength, high pressure resistant design, can withstand 120bar pressure;
2. Open deflector to reduce flow resistance and concentration polarization;
3. High pressure and high retention diaphragm;
Applications:
1. Landfill leachate;
2. High concentration industrial wastewater;
3. RO/NF concentrate in roll form;
4. Industrial concentrated brine;
DTRO/DTNF membrane components include :DTRO/DTNF diaphragm/deflector disk /SUS center pull rod/high pressure vessel/water inlet and outlet pipe and accessories.
