Newsletter – November 2015

In this month’s edition we look at how boat owners can use UV disinfection, report on the dangers of the Amoeba Naegleria Fowleri parasite and share recent publications featuring UV-Guard. There is also another end of year UV system maintenance reminder.


Boat Water Management and Treatment

With the boating season fast approaching, it’s time to highlight how boat operators, both small and large, can manage their water use and discharge.

Water is used for a number of applications on boats and UV disinfection can be implemented to ensure its safe treatment. UV disinfection can be used for:

• Ballast water treatment to meet discharge regulations

• Black and greywater treatment so it can be discharged

• Potable water provision

• Recreational water reuse

Boat operators must ensure their ballast water is pathogen-free before discharging to the ocean.

Under Australian regulations, vessels must adhere to mandatory ballast water requirements to reduce the risk of introducing harmful aquatic organisms into Australia’s marine environment and water supply.

UV-Guard’s UV water treatment systems are compact and energy efficient, making them the perfect solution to on-board boat water management. Our systems can be connected to 12V and 24V DC power supplies, a beneficial feature for some boat owners.

Unlike chlorine treatment, UV water disinfection is chemical free, meaning there is no danger of overdosing. 

UV-Guard have supplied and fitted a water disinfection system into the 37m luxury yacht Kokomo II.


Amoeba, Naegleria Fowleri – the deadly brain eating parasite

Some of you may have seen the report televised on the ABC recently, highlighting the dangers of the Amoeba, Naegleria Fowleri parasite. The report focussed on three child deaths caused by the parasite within a small area of rural Queensland but the problem is much larger. Death's relating to the parasite have been reported across Australia and internationally. The parasite enters a child’s brain through an under developed bone in the nose.

The Amoeba parasite can originate from a number of water sources including dam water and bore water. Any child is at risk if they come into contact with water that has not been sufficiently treated.

UV Disinfection is a cost effective and safe measure to safeguard against the Amoeba, Naegleria Fowleri parasite. A relatively high UV dose is required for protection against the parasite when it is in the cyst form.

See the full article here and contact UV-Guard if you have any concerns about your untreated water supplies, we can develop a solution to destroy the Amoeba, Naegleria Fowleri parasite.


UV-Guard in the News

UV-Guard’s systems and their usefulness in treating boat ballast water were recently featured in the Sustainability Matters publication.

A case study article authored by UV-Guard was also featured in the October edition of Water Technology.


Reminder – End of Year Maintenance

As mentioned in October’s edition, we are fast approaching the December holiday period so now is the time to start planning the shutdown and maintenance of your UV treatment systems.

To ensure your systems are operating at optimal disinfection performance, it’s important to:

• Inspect the UV controller for warnings

• Replace the UV lamp annually

• Remove, inspect & clean or replace quartz thimbles/sleeves

• Replace O-rings annually

• Clean UV intensity sensor lenses

For more information see our operational and maintenance manuals on our website or give us a call.
