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.
