UV Water Purification Systems

Ⅰ. UV ultraviolet water purification system technology principle

 UV ultraviolet water purification system through high-intensity ultraviolet (UV-C band, 200-280nm) irradiation of the water flow, damage to the DNA structure of microorganisms, so that it loses the ability to reproduce, so as to achieve the purpose of inactivating bacteria, viruses, algae and other pathogens. Its core components include:

 ● UV lamp: quartz casing package, to ensure that the UV penetration rate of more than 90%;

 ● ballast: to provide a stable current, to ensure that the lamp continues to work efficiently;

 ● reaction chamber: 304/316L stainless steel, optimize the distribution of the water flow, to enhance the uniformity of irradiation;

 ● intelligent control system: real-time monitoring of ultraviolet intensity, water flow rate and the operating status of the equipment.

 ● Technical advantages: compared with chemical disinfection (such as chlorine disinfection), UV ultraviolet disinfection without the risk of secondary pollution, and high processing efficiency (inactivation completed within 1-2 seconds), especially for residual chlorine sensitive industrial scenarios.

Ⅱ. the core advantages of factory application of UV ultraviolet system

1. Highly efficient sterilization, to ensure production safety

 ● Inactivation rate of ≥ 99.99%: can effectively kill Escherichia coli, Legionella, Cryptosporidium and other common pathogens, to meet the “hygiene standards for drinking water” (GB 5749-2022) and industrial water requirements.

 ● No residual risk: avoid the possible carcinogenic by-products (e.g. trihalomethanes) produced by chemical disinfectants (e.g. chlorine, ozone) to ensure product safety.

2. Low operating cost and remarkable economy

 ● Low energy consumption: the power of single UV lamp is only 30-200W, the energy consumption is only 1/5 of ozone system;

 ● Simple maintenance: no need to add chemicals, only need to regularly clean the quartz sleeve (every 6-12 months) and replace the lamp (every 8000-12000 hours);

 ● Long lifespan: the lifespan of high-quality UV lamp can reach more than 2 years, which reduces the long-term operating cost.

3. Environmental compliance, help sustainable development

 ●  Zero chemical emissions: comply with ISO 14001 environmental management system requirements, reduce the burden of waste water treatment;

  ● Low carbon operation: an automobile manufacturing plant, for example, the annual carbon reduction after the adoption of the UV system reaches 12 tons, helping enterprises to achieve the “dual-carbon” goal.

4. Modular design, adaptable to diversified needs

 ● Flexible expansion: support parallel or series installation, can handle 0.5-500m³/h flow, covering the needs of small workshops to large-scale factories;

 ● Small space occupation: compact design, occupies an area of only 1/3 of the traditional sand filtration + chlorine disinfection system.

Ⅲ. Application Scenarios

 ● Food & Beverage Industry: inactivate microorganisms in production water to prevent product deterioration;

 ● Electronics Semiconductor industry: provide ultra-pure water to avoid ionic contamination of chips;

 ● Pharmaceutical industry: meet the requirements of GMP certification to ensure aseptic production environment;

 ● Cooling water system: inhibit legionella bacteria breeding, prolonging the service life of the equipment;

 ● Wastewater reuse: as a deep treatment unit, to enhance the reuse rate of water.

IV. System Selection Principles

 ● Flow Matching: Select equipment specifications according to the water consumption of the factory, and reserve 20% margin to cope with the peak demand;

 ● Water Quality Adaptation: If the turbidity of the raw water is >5NTU, sand filter or activated carbon filtration device needs to be placed in front of it;

 ● UV Penetration: Ensure that the value of UV-T is ≥85%, or else increase the number or power of the lamps.

V. Daily maintenance specification

 ● Weekly inspection: record the UV intensity, water pressure and other parameters, fluctuations of more than 10% need to be investigated;

 ● Monthly cleaning: use a soft cloth to wipe the outer wall of the quartz casing, to avoid scratches;

 ● Annual maintenance: replacement of aging seals, checking the insulation of electrical lines.
