Product Description

DTRO/DTNF Membrane Disk

Disk tubular membrane technology referred to as DT, common for disk tubular RO (DTRO) and disk tubular (DTNF). The membrane module structure is distinct from the traditional spiral wound membrane.With open flow channels,feed flows through the entrance into the pressure vessel and reach the disk 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 disk again and finally runoff from outlet.The special design makes feed collide with the disk bulge through the membrane surface forming turbulence which increases flow rate and self-cleaning function and long service life of the membrane.

Features

  • High strength design, up to 120 bar operating pressure
  • Open disk with low flow resistance and concentration polarization
  • High pressure resistance and salt rejection membrane

Applications

  • Landfill leachate
  • High concentration of industrial wastewater
  • Spiral wound RO/NF concentrates
  • Industrial high salts water
