Water Quality Parameters
UV disinfection is extremely effective against microorganisms but only if the UV light can pass through the water it needs to treat. This means that the quality of your water is very important in order to ensure complete disinfection. Treated water should be tested for at the least the parameters listed below. If the water exceeds the listed parameters BWT strongly recommends that appropriate pretreatment equipment be installed (equipment required will depend on parameters being treated):
| Hardness | < Hardness should be below 1,5 mmol/l otherwise the quartz sleeve must be cleaned periodically in order to ensure efficient UV penetration. |
| Iron (Fe) + Manganese | The sum should be below 0,1 ppm |
| Turbidity | < 1 NTU |
| UVT (transmittance) | > 85 %/100 mm (Please contact BWT if water has a UVT that is less than 80 %/100 mm for pretreatment recommendations) |
You can have your water tested at a private analytical laboratory or by your local dealer. It is always recommended to install pre-filtration of at least 5 microns prior to a BWT UV disinfection system.
