UV Water Treatment Unit 10 m³/Hour – 2 Lamps, Digital Panel

The UV Water Treatment Unit brings flow capacity, lamp monitoring and a stainless steel body together in a single unit.

The UV Water Treatment Unit is used as the final stage on plant lines that use water in the 10 m³ per hour range and where the water has been clarified by pre-treatment.

In the UV Water Treatment Unit, treatment is a physical process: ultraviolet light disrupts the structure of microorganisms in the water and renders them inactive. For the light to be effective, the water must be clear, it must not pass through the unit too quickly and the lamps must run at full power; the DWQR’s technical guidance on ultraviolet treatment sets out these conditions in detail.

1. 1

   It Comes from Pre-Treatment

   Water that has been clarified by sand, carbon or cartridge filter stages enters the stainless steel body through the 1 1/2 inch inlet.

2. 2

   It Flows Around the Lamps

   Inside the body, the water flows around the two lamps, which are protected by quartz sleeves; the lamps do not come into direct contact with the water.

3. 3

   It Meets the Ultraviolet Light

   The light from the two lamps, totalling 130 watts, disrupts the structure of microorganisms in the water and renders them inactive; no chemicals are added to the water.

4. 4

   The Panel Monitors the Lamps

   The digital panel shows the status and hours of use of each lamp separately, and gives an audible and visual alarm when a lamp fails.

5. 5

   It Goes Out to the Line

   Water that has passed through the light goes out to the pipework through the 1 1/2 inch outlet. Because ultraviolet light leaves no lasting effect in the water, the unit is positioned as close as possible to the point of use or the storage tank outlet.

When choosing the UV Water Treatment Unit, consider peak instantaneous flow, water clarity, hardness and installation conditions together.

The UV Water Treatment Unit keeps its effectiveness with regular lamp and sleeve maintenance.

• Lamps lose intensity over time even while they continue to light; when the hours of use on the panel reach 9,000, the lamp should be renewed without waiting for it to go out.
• If limescale, iron or sediment builds up on the quartz sleeves, the light cannot reach the water. The sleeves should be cleaned regularly; a monthly check is a starting interval that can be extended depending on water quality.
• Take care not to scratch or break the sleeves during cleaning; check the seals and replace them when needed.
• Lamp status and alarms on the panel should be watched regularly, and a lamp that triggers an alarm should be replaced without delay. The pre-treatment cartridges should also be checked at the same service.
• Disconnect the electricity supply before changing lamps or cleaning sleeves; never look at a lit ultraviolet lamp with the naked eye.
• The body must always run full of water. Water left without flow for a long time can be warmed by the lamps; precautions should be taken against water hammer that may occur in the line.
