ODM Industrial Sustainability Solutions Factory & Manufacturer

Global industrial manufacturing is confronting an unprecedented structural transformation. Driven by stringent environmental regulations, aggressive corporate ESG (Environmental, Social, and Governance) commitments, and escalating raw water costs, industrial facilities can no longer afford to treat water as a single-use utility. Sustainable industrial water management has shifted from simple end-of-pipe wastewater treatment to sophisticated closed-loop resource extraction and Zero Liquid Discharge (ZLD) systems.

As an industry-leading ODM Industrial Sustainability Solutions Factory and Manufacturer, Shanghai Tongjie Environmental Protection Technology Co., Ltd. (established in 2010) engineers and fabricates mission-critical water treatment assets. Operating as a recognized National High-Tech Enterprise and Shanghai Specialized & Sophisticated Enterprise, Tongjie bridges process engineering, mechanical precision, and software automation to deliver high-recovery solutions tailored to the world's most aggressive feed water profiles.

Whether mitigating complex organics in petrochemical fracturing fluids, eliminating heavy metals from semiconductor fabrication rinsing, or extracting fresh potable water from high-salinity marine sources, our manufacturing infrastructure delivers guaranteed effluent stability, minimized lifecycle footprint, and optimized Total Cost of Ownership (TCO).

Conventional spiral-wound reverse osmosis (RO) membranes are restricted by hydraulic flow channel geometries and vulnerable to colloidal fouling when processing total dissolved solids (TDS) beyond 45,000 mg/L. Tongjie overcomes these thermodynamics barriers through four core membrane and thermal separation platforms:

Open-Channel DTRO Hydraulics: Mitigating Concentration Polarization

Unlike spiral membranes where narrow feed spacer channels create dead zones prone to scaling, our DTRO modules utilize open-channel disk architecture. High-velocity hydraulic sweeps across the membrane cushions prevent particulate adhesion and break down the boundary concentration layer. This enables stable operation even in oilfield fracturing returns with suspended solids (SS) up to 100 mg/L and silica levels that would foul standard spiral elements within hours.
