What models of ONYX UV equipment are available?
2025-07-28

ONYX UV equipment mainly includes:
①ONYX-EX-U(Low-pressure amalgam lamps, flow rates 11-600 m³/h);
②ONYX-Extrem-SY(Medium-pressure, 40-300 m³/h, broad-spectrum sterilization sterilization);
③ONYX-ONEUV(Sanitary clamp quick-connect lamps, flow rates 0.5-40 m³/h);
④ONYX-Clear-SY(Medium-pressure lamps, flow rates 35-450 m³/h, suitable for high-quality water).These systems cover a wide range of application scenarios.
What are the advantages of ONYX UV light?
2025-07-28

ONYX UV disinfection equipment offers the following advantages:
① Highly effective sterilization: Using CFD flow simulation to optimize light intensity distribution, the sterilization rate is ≥99.9%;
② Intelligent control: Supports IoT remote monitoring and real-time dosage adjustment;
③ Long-lasting stability: Amalgam lamps have a lifespan of up to 12,000 hours and are equipped with an automatic cleaning system;
④ Hygiene and safety: Made of food-grade materials, they meet drinking water standards (such as GB5749).
What is the dosage of UV disinfection in different areas?
2025-07-28

The UV disinfection dosage requirements for various applications are as follows:
① Drinking water: ≥ 40 mJ/cm² (GB/T 19837-2019 standard);
② Secondary water supply: Normally 16 mJ/cm², switching to 40 mJ/cm² when residual chlorine is insufficient;
③ Municipal wastewater: 20 mJ/cm² (Class A standard);
④ Recycled water: 30-80 mJ/cm² (adjusted depending on application). Medium-pressure UV can meet higher requirements.
What factors influence the effectiveness of UV disinfection?
2025-07-28

Factors influencing UV disinfection include water quality (such as UV transmittance (UVT)), microbial species and their resistance, UV dose, exposure time, water turbidity, and suspended solids.
Which is better for water supply applications: low-pressure UV or medium-pressure UV?
2025-07-28

Low-pressure UV primarily emits 254nm monochromatic light, offering high sterilization efficiency and low cost, making it suitable for general water treatment. Medium-pressure UV emits a broad spectrum of UV light, providing a more thorough sterilization effect. It's particularly well-suited for high-flow and demanding applications, such as the drinking water and food industries. In the water supply sector, medium-pressure UV is generally preferred due to its greater sterilization capacity and adaptability.
What are the advantages of UV disinfection or sterilization over chlorine disinfection?
2025-07-28

Compared to chlorine disinfection, UV disinfection offers advantages such as no chemical residue, no byproducts, ease of operation, broad-spectrum sterilization, and safety and environmental friendliness. It is particularly suitable for applications requiring high water quality, such as swimming pool disinfection, as it avoids the irritation of residual chlorine to aquatic ecosystems and the human body (eyes and respiratory tract).
How does UV disinfection or sterilization work?
2025-07-28

UV disinfection uses ultraviolet light in the UVC band (200-280nm) to irradiate microorganisms, destroying the DNA or RNA structures within their cells, rendering them unable to replicate and reproduce, thereby achieving an inactivation effect. Ultraviolet light with a wavelength of 254nm is particularly effective at damaging DNA. Medium-pressure UV light can also destroy microbial proteins and cell tissue, achieving a more thorough sterilization effect.
What are the maintenance instructions for the photochemical advanced oxidation process?
2025-07-28

The photochemical advanced oxidation process requires regular cleaning of the quartz sleeve, replacement of the UV lamp every 3,000-9,000 hours, and inspection of the seals and ballast. During maintenance, the power should be turned off, and specialized tools should be used for disassembly and assembly. The PLC system monitors operating status to ensure high efficiency and stability.
How does the photochemical advanced oxidation process remove toxicity?
2025-07-28

Photochemical advanced oxidation uses OH oxidation to destroy the structure of toxic substances, such as phenols and cyanides, converting them into low- or non-toxic substances. It also degrades chemically active agents such as antibiotics and hormones, decomposes organic complexes, reduces bioinhibition, and significantly reduces wastewater toxicity, ensuring the safety of subsequent treatment.
How does the photochemical advanced oxidation process improve the biodegradability of wastewater?
2025-07-28

The photochemical advanced oxidation process uses hydroxyl radicals (·OH) to degrade macromolecular organic matter, breaking chains and opening rings, and introducing hydrophilic functional groups (such as hydroxyl and carboxyl groups). This process converts refractory substances into readily biodegradable small molecules (such as short-chain fatty acids), significantly improving the B/C ratio (BOD5/COD) and biodegradability of wastewater. This process also removes toxic substances, improves the environment for microbial growth, and creates favorable conditions for subsequent biological treatment.
