DTRO plant

DTRO plant is engineered specifically for high-pollution, high-salinity wastewater that conventional spiral-wound RO cannot handle. The unique open-channel disc-and-tube design allows the system to process feed water with COD up to 20,000 mg/L, TDS up to 80,000 mg/L, and SDI up to 15-conditions that would rapidly foul standard RO membranes. Operating at 75-120 bar, DTRO achieves 95-98.5% salt rejection with system recovery rates of 60-80%.

Key advantages:

• Open-channel design prevents fouling and clogging in high-COD wastewater

• Operating pressure: 75-120 bar (up to 160 bar for second-stage concentration)

• Tolerates feed SDI up to 15 and suspended solids up to 2,500 ppm

• Modular membrane columns allow individual replacement and easy scaling

• Membrane service life: 3+ years even in aggressive leachate applications

Typical applications: Landfill leachate treatment, hazardous waste disposal center wastewater, coal chemical high-salt effluent, zero liquid discharge (ZLD) systems

FAQ:

Q: Why choose DTRO over conventional RO for leachate?

A: The open flow channel and turbulent flow pattern prevent membrane fouling that cripples spiral-wound RO within weeks on leachate.

Q: What is the typical operating cost?

A: DTRO operating costs range from $2-5 per m3 depending on feed water characteristics and local energy rates.
