The Disk Tube (DT) membrane technology includes Disk Tube Reverse Osmosis (DTRO) and Disk Tube Nanofiltration (DTNF).
The main components of a DT module are a tubular shell and layers of membrane cushions and Hydraulic discs, held and tightened by a center tie rod.
The width between the two hydraulic disks is 4-6 mm. There are plastic dots distributed in a specific pattern on the disk surface. These dots enable the raw water to form turbulences as it flows along the membrane surface, thereby prevents scaling on the membrance surface. It is also helps when the modules were being cleaned with cleansing solvents.
