When temperatures rise in summer, break tanks and water buffer tanks are at risk of rapid bacterial development. With stagnant water, bacteria have a chance to multiply and attach to the walls.
Water with a temperature between 20°C and 50°C is particularly susceptible to bacterial growth. Eventually, those bacteria cause a biofilm (slime layer) on the tank walls.
Preventing problems with UV light
A biofilm in the water is often undesirable and can cause practical problems, such as clogged pipes or pumps. But problems in the production process can also occur, such as bacterial contamination or corrosion.
With UVC light, you can prevent biofilm in water tanks using a lamp in the water. This solution can be used in tanks from 200 litres. One UVC lamp is enough for about 1 to 2 m3 of water. The UVC lamps (and if necessary the fittings) are of course completely waterproof. Optionally, they are equipped with splinter protection and are therefore food-safe according to the HACCP standard.
A flow-through system can be used to disinfect water in a (ring) pipe; UVC light also works against Legionella bacteria.
