Medium-pressure UV-Oxidation

Medium-pressure ultraviolet oxidation (MPUV-Oxidation) is an advanced oxidation technology that uses ultraviolet (UV) light to excite oxidants to generate strong oxidative free radicals (primarily ·OH hydroxyl radicals), effectively degrading organic pollutants in water. MPUV-Oxidation boasts a waste-free production process (no secondary pollution), broad-spectrum performance (suitable for most wastewater treatment), effective treatment of difficult-to-degrade and high-concentration wastewater (up to 300,000 mg/L COD), and significantly improved bioavailability (up to nearly 100%). It is widely used in industrial wastewater pretreatment and advanced treatment.

Advantages

  • The UV-Oxidation reactor utilizes high-intensity, high-energy-density, and high-penetration reactors, ensuring effective UV output far exceeding that of competitors.

  • The reactor's ingenious flow path design controls the flow layer, unaffected by water color or turbidity.

  • By integrating CFD simulation technology with practical application, the high-speed swirl flow pattern ensures optimal reaction conditions within the diffusion boundary layer.

  • The fluid dynamics turbulence design and friction prevent waste accumulation within the pipe.

  • The unique UV reflective layer design utilizes the principle of total reflection to evenly distribute and fully utilize UV light, significantly improving UV efficiency and reducing energy consumption.

  • Multiple protections ensure zero UV leakage and safe production. Borosilicate protective tube + stainless steel cover.

Technical Principle

UV disinfection technology utilizes ultraviolet light (wavelength 254nm) to damage the DNA/RNA structure of microorganisms, rendering them unable to reproduce and effectively sterilizing the water. Compared with chemical disinfection, UV treatment requires no chemical additives, produces no disinfection by-products (DBPs), achieves high inactivation efficiency against bacteria, viruses, and spores, and requires only seconds of contact time. It is a safe, environmentally friendly physical disinfection method.

ONYX UV equipment features optimized reactor hydraulic design ensuring uniform UV dose distribution, paired with an automatic cleaning system to maintain lamp transmittance for long-term stable operation. The equipment supports online UV dose monitoring and real-time operational status feedback, and can be seamlessly integrated into existing SCADA systems.
