Product description
UV water disinfection systems are designed to inactivate microorganisms in water using ultraviolet radiation. These systems provide chemical-free disinfection for drinking water, process water, and industrial water treatment systems. UV treatment is widely used in point-of-use installations, private water supplies, commercial systems, and industrial water loops where microbiological control is required.Technical overview
A UV disinfection system consists of a stainless steel reactor chamber containing one or more ultraviolet lamps enclosed in quartz sleeves. As water flows through the reactor, microorganisms are exposed to UV radiation that disrupts their DNA, preventing reproduction and effectively neutralising microbial contamination. Compact single-lamp systems are typically used for small commercial or residential installations, while higher capacity systems may incorporate multiple lamps for increased flow rates and disinfection capacity. :contentReference[oaicite:1]{index=1}Operating principle
Water flows through a stainless steel UV reactor chamber where it is exposed to ultraviolet light generated by specialised UV lamps. The ultraviolet radiation penetrates microorganisms such as bacteria, viruses, and protozoa, damaging their genetic material and preventing replication. This process renders microorganisms inactive without altering the chemical composition of the water. To ensure effective disinfection performance, UV systems are typically installed after pre-filtration to remove particles that could shield microorganisms from UV exposure. :contentReference[oaicite:2]{index=2}Material options
Typical materials of construction include:- 304 stainless steel reactor chamber
- Quartz UV lamp sleeve
- Silicone or Viton O-rings
- Aluminium mounting components
Available micron ratings
UV disinfection systems do not operate using filtration micron ratings. Microbial inactivation performance is determined by UV dosage, system design, and water quality parameters such as turbidity and UV transmittance. Effective pre-filtration is typically recommended to improve UV exposure efficiency and ensure reliable disinfection performance. :contentReference[oaicite:4]{index=4}Design and construction
