UV Disinfection and Sterlisation Treatment Technologies

WestWater Enterprises specialises in potable water treatments and disinfection through industry leading technologies in gas chlorination, UV disinfection and electro chlorination.

Treatment and disinfection is important to make water safe to drink and for use in domestic and industrial applications.

According to the Australian Drinking Water Guidelines (ADWG): Ideally, drinking water should be clear, colourless, and well aerated, with no unpalatable taste or odour, and it should contain no suspended matter, harmful chemical substances, or pathogenic microorganisms.

In other words, it should not contain chemicals, organic substances or organisms that can make us sick. It should also be at a reasonable temperature and free of odours, tastes and colour.

The guidelines also specify that it ‘…on the current state of knowledge, is safe to drink over a lifetime: that is, it constitutes no significant risk to health’.

When most Australians turn on the tap, we expect a continuous supply of drinking water that meets these guidelines.

WestWater supplies water disinfection systems to help utilities such as the WA Water Corporation, PowerWater and SEQ Water conform to the requirements of the ADWG.

Our water disinfection technology includes:

  • Gas chlorination – The use of chlorine gas as the prime water disinfection agent in gas chlorination treatments. Associated products include vacuum regulators, chlorinators, ejectors and residual chlorine analysers.
  • UV water disinfection – A range of environmentally friendly water disinfection systems using ultraviolet light technology to kill bacteria and micro organisms.
  • Electro chlorination – An on-site sodium hypochlorite generating system which offers a cost effective, reliable and safe water disinfection treatment.

Instrumentation

We also supply instrumentation for quality monitoring, assessment and residual chlorine analysis.

Residual chlorine analysis is an important measure in potability as its presence indicates the likely absence of disease-causing organisms.

Residual chlorine analysis can indicate that:

  • A sufficient amount of chlorine was added to inactivate most of the bacteria and viruses that cause disease
  • There is protection from recontamination during transport or storage
  • An absence of unhealthy micro organisms

Tests for residual chlorine in treatment systems can include:

  • Free residual chlorine – residual consisting of dissolved chlorine gas, hypochlorous acid, and hypochlorite ions
  • Combined residual chlorine – residual consisting of other forms of chlorine such as chloramines which are capable of killing bacteria and oxidising organic matter
  • Total residual chlorine – the sum of the free residual chlorine and the combined residual chlorine
