Get a Solution Now View Specifications The DTRO Advantage Transform the complexity of treating high-concentration wastewater into a streamlined, reliable process. The Core Problem Standard spiral-wound RO membranes clog easily when treating complex fluids, leading to frequent downtime and high replacement costs.

Our Solution Our DTRO Membrane module utilizes a patented open-channel design combined with high-pressure capabilities (up to 160 bar). Unmatched Anti-Fouling The unique disc-and-tube open flow channel promotes turbulent flow, preventing suspended solids and scaling from settling on the membrane surface.

Minimal Pre-treatment Unlike traditional RO, our DTRO modules can handle high SDI (Silt Density Index) and turbidity directly, saving you massive investment in pre-treatment systems.

Longer Lifespan Designed for durability, our membranes typically last 3+ years even in harsh leachate applications, significantly reducing your OPEX. Easy Maintenance The modular design allows for individual disc or membrane sheet replacement without discarding the entire module.

Application Fields Designed for industries where water quality is poor and recovery targets are high.

Landfill Leachate Treatment Effective treatment of old and fresh leachate Consistently meets strict discharge standards (COD, BOD, Ammonia Nitrogen removal) Zero Liquid Discharge (ZLD) High-pressure concentration for industrial wastewater (textile, pharmaceutical, plating) Maximizes water reuse and minimizes brine volume for evaporators Desalination & Marine Use Reliable potable water generation from high-salinity seawater or brackish water on ships and islands Emergency ion Manufacturing We operate a state-of-the-art, 10,000-square-meter production facility dedicated exclusively to special membrane technologies.

Automated Welding & Assembly We utilize ultrasonic welding technology to ensure every membrane cushion is leak-proof and pressure-resistant. ISO Certified Quality Control Every single DTRO module undergoes a rigorous high-pressure test before leaving our factory. We adhere to ISO 9001:2015 standards.

R&D Center Our in-house lab continuously tests membrane sheet chemistry to improve salt rejection rates and chemical stability against aggressive cleaning agents. Stock & Delivery We maintain a strategic inventory of standard 75-bar and 90-bar modules to ensure rapid deployment for your urgent project needs.

Application Cases: Proven Results Case Study 1 Municipal Landfill Leachate Project Capacity: 200m³/day Challenge: The client was struggling with a spiral RO system that fouled every 3 days due to high COD (25,000mg/L) and conductivity. Solution: Retrofitted with a Two-Stage DTRO System operating at 75 bar.

Result: Cleaning frequency reduced from every 3 days to once every 3 weeks Permeate COD consistently below 60mg/L System recovery rate achieved >80% Case Study 2 Chemical Plant ZLD Concentration Capacity: 500m³/day Challenge: High salinity wastewater needed to be concentrated before the evaporation crystallizer to reduce energy costs.

Solution: Installed High-Pressure (120 bar) DTRO modules.

Result: Concentrated TDS from 30,000 ppm to 100,000 ppm Reduced evaporator energy consumption by 40% Achieved seamless integration with existing biological systems Customer Reviews Real Feedback from Industry Professionals ★★★★★ "We shifted to your DTRO modules for our leachate plant last year.

The difference in fouling resistance is night and day compared to our old setup. We are saving roughly 30% on chemical cleaning costs alone." DC David C. Operations Manager, Waste Management Solutions ★★★★★ "Technical support was fantastic.

They didn't just sell us the membrane;they helped simulate the process and guided us on the optimal operating pressure. The modules are performing exactly as promised under high load." SL Sarah L. Senior Environmental Engineer, ZLD Tech Corp ★★★★★ "Reliable delivery and consistent quality.

As an OEM system integrator, I need membranes that don't fail during commissioning. These DTROs are solid workhorses." RM Rajiv M. Procurement Director, Aqua. Pure Industrial Frequently Asked Questions How does DTRO differ from standard Spiral Wound RO?

Spiral wound membranes have narrow flow channels (spacers) that trap dirt easily. DTRO uses an open-channel design with discs, creating turbulent flow that prevents clogging, making it suitable for high-pollution water. What is the cleaning frequency for your DTRO membranes?

It depends on the water quality, but generally, DTRO membranes require significantly less frequent cleaning than spiral RO. For leachate, typical cleaning intervals are 1-4 weeks. Can individual parts of the module be replaced? Yes, this is a major advantage.

Unlike spiral elements which are sealed, the DTRO module can be opened. You can replace specific membrane sheets or discs if they are damaged, reducing long-term maintenance costs. What is the maximum operating pressure? Our standard modules handle 75 bar and 90 bar.

We also manufacture high-pressure series capable of 120 bar and up to 160 bar for maximum concentration requirements. Do you provide technical support for system design? Absolu imulation and recommend the exact module configuration. Ready to solve your wastewater challenge?
