DTRO: The Unmatched Solution for High-Salinity Industrial Wastewater
March 6, 2026
In industrial wastewater treatment, salinity is the ultimate barrier—conventional RO systems fail at 10,000+ ppm TDS, leaving 70% of high-salinity streams untreated. DTRO (Disc Tube Reverse Osmosis) changes everything. At Qinrunze Environmental, we’ve engineered DTRO systems that process 50,000+ ppm TDS streams with 99.5% efficiency, turning impossible waste streams into reusable water. Here’s how it works—and why it’s the industry’s missing link.

“Standard RO couldn’t handle our oil-refinery brine. DTRO did—without a single shutdown in 18 months.” — Operations Director, Shandong Petrochemical Plant
