Disk tubular (DT) is a patented membrane technology commonly with three types: DTRO (DT Reverse Osmosis), DTNF (DT Nanofiltration) and DTUF (DT Ultrafiltration). DT membrane modules are specially designed for high concentration wastewater treatment (such as landfill leachate) with excellent stability and high performance. The permeate water from DT modules can easily fulfill the stringent discharge requirement. Our DT product have been widely and successfully applied to the wastewater treatment industries globally.

Technical features

• The basic membrane element is made of two concentric reverse osmosis membrane pieces;
• The feed stream flows through two “S” shape channels in the DT module;
• Hydraulic discs are installed between the membrane elements with the interval of 4 mm. The bumps with unique pattern on the surface of hydraulic disc are designed to improve the feed permeability and enhance the cleaning process.
• The distance from the outside edge of the membrane element to the center of the module is optimally short and the number of the membrane element in the DT modules are standardized.
• The operational pressure of our DTRO module is 75 ~160 bar.
