The Water Company supplies UV water sterilisers and replacement parts for domestic, commercial and industrial water purification systems. Ultraviolet (UV) water treatment uses UV light to help inactivate susceptible microorganisms as water passes through a specially designed treatment chamber, providing an additional layer of microbiological protection without adding disinfectant chemicals during the UV process.
Our range supports the installation, servicing and maintenance of UV water treatment systems used in homes, businesses, borehole water installations and larger water purification plants.
UV water sterilisers:
UV sterilisers are commonly installed as part of a water purification system to help control microbiological contamination. They are particularly useful when treating water from boreholes and other sources where microbiological quality needs to be addressed.
UV steriliser replacement parts:
Regular servicing is essential to maintain the performance of a UV water treatment system. Depending on the model, replacement parts may include:
UV lamps: Replace at the manufacturer’s recommended interval to maintain the required UV output.
Quartz sleeves: Protect the lamp while allowing UV light to pass into the water.
Electronic ballasts and controllers: Provide the electrical control required for compatible UV units.
Seals and O-rings: Help maintain watertight connections during correct assembly.
Other compatible components: Model-specific spares for servicing and repairs.
Choosing and maintaining your UV system:
The correct UV steriliser depends on the required flow rate, water quality, UV dose and installation conditions. Suspended solids, turbidity and colour can reduce treatment effectiveness, making appropriate pre-filtration important.
Routine maintenance may include cleaning the quartz sleeve, inspecting seals and replacing the UV lamp according to the manufacturer’s instructions. UV treatment does not leave a residual disinfectant in the water, so suitable storage hygiene and any necessary additional disinfection measures remain important.
