Last Newsletter of 2015

Welcome to the final UV-Guard newsletter of 2015. We’d like to take this opportunity to thank our customers for their continued business throughout 2015. We wish everyone a very happy and safe Christmas.

The UV-Guard office will be closed on Wednesday 23rd December and will reopen on Monday 4th January. However, we can be contacted at and 02 9631 4900 during this time. Any orders placed over the holiday period will be shipped on Monday 4th January.

In this month’s edition we look at the results of a scientific trial involving UV-Guard for horticultural applications, present a recent project showing the integration of our PLC controller with a turbidity meter, and share recent news articles featuring UV-Guard.


Scientific trial - UV water disinfection for horticulture confirms the effectiveness of UV

Last year, we informed you about a scientific trial involving UV-Guard, The NGIA (Nursery & Garden Industry Australia), Sydney University and the NSW DPI (Department of Primary Industries).

Three types of water disinfection were tested, including UV, for their effectiveness in disinfecting irrigation water for horticultural uses.

The results of the investigation are now available and can be read in the NGIA’s August Nursery Paper. To summarise, it was concluded that UV water treatment is an effective form of protection against most pathogenic risks in a horticultural environment.

 UV-Guard have a number of installations at council and private nurseries across Australia. Our engineers have a collaborative relationship with the NGIA and we understand their requirements along with the requirements of nursery owners.


PLC integration with turbidity meter 

We supplied a UV disinfection system for a large scale drinking water application recently and one of the requirements for the project was to measure turbidity in real time.

UV-Guard supplied a Thermo Fisher turbidity meter which was controlled and monitored by our PLC. 

By integrating the turbidity meter into our PLC we were able to show all faults on one display, making it easier for operations staff to assess UV intensity, high turbidity levels and other system parameters.

Other features included the activation of a solenoid valve designed to close when turbidity was too high or when UV intensity was too low. This meant that treated water that was not in line with specifications, was not consumed.


UV-Guard in the News

The Australian Water Association’s Water Journal featured UV-Guard’s water disinfection systems and their use in a domestic rural application to ensure clean safe tank water without the use of chemicals.
