UV is used for disinfection and removal of organic and inorganic contaminants, including chlorine, ozone and total organic carbon (TOC). UV technology is often used where conventional chlorine disinfection cannot be applied and can be used in the advanced oxidation process (AOP). Key benefits of UV technology include: improve the taste, color, pH or odor of water, requires no storage, handling or transportation of toxic or corrosive chemicals, effective at inactivating a wide range of microorganisms including chlorine tolerant pathogens, and water reuse capabilities to meet sustainability objectives.

UV light works by causing permanent damage to the DNA found in all living species. Once the DNA becomes damaged, or dimerized, the organism is unable to carry out the routine cell functions of respiration, the assimilation of food, and replication. Once the cell is rendered non-viable the organism quickly dies.
The majority of UV applications are now performed in a closed vessel. In pipe systems, offer significant operator benefit, smaller footprint, faster installation, and reduce lifetime cost. Isn’t it time to stop accepting how it’s always been done, and start asking why not put it in a pipe?
There are three main differences: lamp power, electrical efficiency, and the type of UV light produced. Each lamp type is best suited for different applications, which our water treatment experts will be pleased to explain to you.
UV dose is calculated from the flowrate, the water transmittance and the lamp power. The dimension of UV dose is m J cm-2. We uses advanced Computational Fluid Dynamics (CFD) to accurately predict the UV dose that the water will receive, and then systems are validated by a third party test house to verify the predicted UV dose closely matches the actual delivered UV dose.
UV transmittance (UVT) is a measurement to determine how much UV light passes through a sample of water compared to distilled water. Dissolved organics, suspended matter, color, and certain UV light absorbing metals are the main absorbers of UV light. It is the key factor in properly sizing a UV system to operate effectively.
