UV disinfection systems in Sydney

Last Updated on May 16, 2023 by

Not all UV disinfection systems in Sydney are designed the same way. When it comes to choosing the right system for your needs, there are a lot of important things you need to consider to ensure you get the best system. Here are some tips to help you choose the right system for your needs.

Know the quantity of water you use

If you want to have peace of mind and protection from water contaminants, it is important to choose the right size of a UV treatment system.

Flow rates of the system

UV water disinfection systems measure water flow rates in GPM or gallons per minute. This indicates how much water that can flow through the system. Water may not be treated effectively if the system can’t handle the flow rates for your property. It is therefore important for homeowners to oversize their treatment system than undersize it.

UV dose

This refers to the amount of ultraviolet energy from the lamp to the water being treated as it flows through the system. The UV dose is typically expressed in mJ/cm2. Giardia, E-coli require a UV dose of about 10 mJ/cm2 for them to be activated. The whole house ultra violet disinfection systemsusually has flow rates of about 30 mJ/cm2. This is sufficient for most residential homes. If you are on a private well, it is important to know what is in your water before you buy ultraviolet disinfection systems. It is therefore important that you find a laboratory that can provide proper water analysis services including testing for the contaminants listed above.

Space requirements

Some system installations take up a lot of space compared to others and some are more compact than others. One style is not more effective at water treatment than the other but more compact systems use a brighter lamp and may be more expensive. UV systems are usually installed vertically. However, they can also be installed horizontally depending on expert recommendations.

When determining the space required for UV system installation, it is important to allow at least double the size of the system dimensions so that there is enough room for replacing the sleeve and lamp. It is also important to consider the space required for any pre-filtration systems.

Other features

Most systems come standard with a display that indicates how many days remain until the lamp needs replacement? Other systems come with controllers with LED lights indicating the proper function of different components of the system. Some newer systems come with quality touch screen displays. However, it is important to remember that UV systems can come with a wide range of options. The most common option that can be added by homeowners is the sensor. It is also important to remember that commercial applications are likely to add a solenoid shutoff valve.


If you are choosing UV disinfection systems in Sydney, it is important to know what is in your well water. Private wells aren’t regulated so contamination can go undetected. That is why it is important to have the water tested by a lab before knowing the best system to choose.
