DTRO, short for Disc Tube Reverse Osmosis, is a high‑efficiency membrane technology for treating challenging wastewater. Its unique open flow channel and disc‑stack design create strong turbulence, greatly reducing fouling and clogging. It performs well with high salinity, high turbidity, and high organic content wastewater such as landfill leachate and industrial effluent. DTRO systems feature high removal rates of salts and organics, compact structure, easy maintenance, and stable effluent quality. They are widely used in waste treatment, zero liquid discharge, and water reuse projects, offering reliable and cost‑effective purification.
