Disc tube membrane technology

Special membrane technology specially used for the treatment of high pollution and high salinity wastewater.

Product Details

       DT membrane technology, namely Disc Tube Module (Disc Tube Module), is a special membrane technology specially designed for the treatment of highly polluted and high salinity wastewater. We develop more series of products. Its special structure membrane separation module and unique fluid dynamics design make it have super anti-pollution ability, even for high COD, high SDI wastewater can be directly treated. At the same time, its independent installation method and high pressure resistance are the most ideal membrane technology for high-salinity wastewater treatment. We have two types of membranes, namely disc tube reverse osmosis (DTRO) and disc tube nanofiltration (DTNF). There are a variety of configuration options according to different wastewater and needs, which enriches wastewater treatment solutions.
