The UV performance test data can be found on our data sheets for each specific grade. Light Stability Characteristics Ultraviolet (UV) Stabilization Plastics are attacked and deteriorate when exposed to direct sunlight. When plastic tanks absorb the sun's ultraviolet light, the UV energy excites the polymers’chains, causing them to break.
In many countries, UV light is becoming the most common means of disinfection because of the concerns about the impacts of chlorine in chlorinating residual organics in the treated sewage and in chlorinating organics in the receiving water. As with UV treatment, heat sterilization also does not add chemicals to the water being treated. However ...
Pressure Vessel Direct Chill System - The combination of a pressure vessel, which protects the water in the tank from air-borne contamination, and a direct chill system which cools water coming from the mains quickly. Pressure Vessel - A sealed pressure vessel is filled at a lower pressure within the water cooler. As such, the water does not ...
Warning labels: Labels alert users to the dangers of UV light. Interlocking systems: Shielded systems, such as closed water tanks or air circulation units, often have interlocks that automatically shut off the UV lamps if the system is opened for human access. Clear viewports that block UV-C are also available.
Ultraviolet (UV) light induces the formation of covalent linkages on DNA and thereby prevents microbes from reproducing. Without reproduction, the microbes become far less dangerous. Germicidal UV-C light in the short wavelength range of 100–280 nm acts on thymine, one of the four base nucleotides in DNA.
Ultraviolet light (UV) is very effective at inactivating cysts, in low turbidity water. UV light's disinfection effectiveness decreases as turbidity increases, a result of the absorption, scattering, and shadowing caused by the suspended solids. The main disadvantage to the use of UV radiation is that, like ozone treatment, it leaves no ...
