Ultraviolet Sterilizers

Ultraviolet (UV) is a non-chemical process used to disinfect air and water. Ultraviolet is popular in industries where the addition of taste altering chemicals is problematic (a good example is the bottled water industry). CWC's potable and process water UV lamps transmit UV-C light and are designed to produce 30 microwatt seconds per square centimetre of ultraviolet light.

How Ultraviolet Sterilizers work

CWC's range of PVC and stainless steel UV systems contain one or more germicidal ultraviolet lamps.

We use Philips low pressure mercury vapor tubes, producing ultraviolet wavelengths that are lethal to micro-organisms. Approximately 95% of the ultraviolet energy emitted is at the mercury resonance line of 254 nanometers, which is highly lethal to virus, bacteria and mold spores.

The water passing across a UV lamp is exposed to the UV light, de-activating the genetic material of micro-organisms in the water supply, preventing them from re-producing. Due to the short life-span of most micro-organisms, the water is considered sterile after passing through the UV chamber.
