DTRO membrane technology, also known as disc-tube membrane technology, is divided into two main types: DTRO (Disc-Tube Reverse Osmosis) and DTNF (Disc-Tube Nanofiltration). It is a patented membrane separation technology. This technology was developed by the company specifically for high-concentration industrial wastewater, industrial brine, spiral RO/NF concentrate, and landfill leachate fields.

Water production and desalination rate are based on the following test conditions: FR:2000mg/l NaCL solution, test pressure 15.5bar, 25 ℃; SW:3 2000mg/lNaCL solution, test pressure 55bar, 25 ℃, pH:7-8;
The water yield of a single component may vary in the range of + 20%, and the actual water yield will vary according to the quality of the influent.
