Other Disinfection Products - UV Water Treatment

The main concern with chemical treatment is the formation of disinfection by-products that are left behind in the water. In particular, chlorine is suspected to increase the levels of carcinogenic substances as a result of reactions with organic material in the water.

During the early days of water treatment, scientists discovered that in nature the sun was responsible for natural control of bacteria in rivers and lakes.

ESG Waterwise Ultra Violet Systems are designed to reproduce the power of the sun, producing ultra violet rays to destroy pathogenic micro-organisms within a matter of seconds.

How it Works

Ultra Violet disinfection is a non-chemical treatment, destructive to all micro-organisms.

Ultra Violet light with a wavelength of 254 nm is the most effective range for disinfection, often referred to as the "Germicidal Range".

The Ultra Violet light penetrates the outer cell membrane of the organism, passing through the cell body, where it dissociates the DNA (deoxyribonucleic acid) structure of the organism, thus preventing further multiplication.

Advantages of ESG Waterwise UV systems

  • Simple Application - ESG Waterwise UV Systems are supplied with standard fittings, either BSP or Flanged connections, depending on the system selected. (Hygienic fittings are also available on selected models – see specification)
  • Reliable Disinfection - All systems are sized on their performance at the end of lamp life, thus ensuring complete disinfection during the service life of the lamps, typically 8,000 to 10,000 hours.
  • Monitoring - ESG Waterwise UV Systems have a wide range of monitoring options available. Please refer to technical specification for further details.
  • Lamps - High intensity, low-pressure amalgam lamps have excellent temperature stability, thus giving extended quartz sleeve and lamp life. Lamp life 8,000 to 10,000 hours (depending on system selected)
