What’s the Issue?


How can I ensure the correct maintenance regime is being applied to my UV water treatment system?

Where can I purchase a replacement lamp/bulb from?

How do I fit a replacement lamp/bulb and quartz sleeve?

What is your obligation?


All treatment units must be operated and maintained according to manufacturers’/suppliers’ instructions. In particular, cartridges, filters and UV lamps must be replaced at recommended intervals. A simple system may be maintained by its owner, but specialist companies should be used for more complex systems.

Copies of manufacturers’/suppliers’ operating and maintenance instructions should be retained by the supply owner. In addition, a maintenance log should be maintained by the owner to record details of maintenance carried out and schedules for future maintenance.

Risks


By not undertaking regular checks and maintenance to the UV water unit you could be leaving it susceptible to a failure which could mean that the system may not operate correctly or effectively and leave your water system at risk to bacteria.

Ultra violet water systems are designed to kill bacteria in water. These systems use special lamps that emit UV light of a particular wavelength that have the ability, based on their length, to disrupt the DNA of micro-organisms. They are an excellent method of ensuring your water is safe and drinkable.

Whilst most UV systems are relatively the same, there are often some differences in the maintenance of a particular systems. We recommend referring to the manufacturers guidelines for the appropriate and correct maintenance of your individual UV water system. To achieve optimal performance from you UV system, it is recommended that proper maintenance is undertaken by following the maintenance schedule and instructions from the manufacturers guidelines.

The UV water system should be checked periodically for the following: –

UV Lamp or Bulb Replacement – these should be changed on an annual basis or when repair or replacement is required. This is essential as the UV lamp is the heart of the UV treatment system. These lamps work very differently from normal bulbs and are designed to solarize and not burn out, meaning that over time their light wave intensity reduces to around 60% of what a normal UV lamp would provide. Therefore, it is important to replace the lamp/bulb after a period of 1 year or after 9000 hours of continuous use. If these are not replaced then the UV light may not provide the correct light dosage to effectively kill bacteria.

UV Sleeve Replacement & Cleaning – the UV lamp is protected by a UV quartz sleeve and requires replacement every 2 years. The system can often carry minerals, sediment and other debris which after time can build up on the UV quartz sleeve and can inhibit the light from penetrating the water. This can lead to microorganisms passing through the water without being killed. The glass on the sleeve should also be cleaned on a regular basis.

Pre-Filtration Monitoring – it is highly likely that if you have a UV water system in place then a separate pre-filter is normally present which protects the UV unit to ensure it functions correctly. These must also be maintained as these will often have such things as sediment filters, carbon filters & other systems which may require periodic replacement.

Water Supply Monitoring & UV System Performance – it is recommended that the water should be tested for bacteria every 6 months or at least annually.

UV Light Dosage Monitoring – UV systems are generally equipped with light intensity meters or sensors that will provide a warning signal when the UV dose is too low to provide adequate disinfection and will also indicate when the quartz sleeve requires cleaning and when the bulb/lamp requires replacement. It is a good idea to ensure you keep a regular eye on this to ensure the system is working effectively.
