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.
It is imperative that you have your water tested for at the least the parameters listed below. If the
water exceeds the listed parameters Crusader strongly recommends that appropriate pretreatment
equipment be installed (pretreatment will depend on parameters being treated):
Hardness : <7 gpg (120 mg/L) – if hardness level is 7 gpg or
slightly below the quartz sleeve must be cleaned
periodically in order to ensure efficient UV
penetration; if above the water must be softened
Iron (Fe): <0.3 ppm (0.3 mg/L)
Manganese (Mn): <0.05 ppm (0.05 mg/L)
Turbidity: < 1 NTU
Tannins (organics): <0.1 ppm (0.1 mg/L)
UVT (transmittance): >85% (Please contact Crusader if water has a UVT
that is less than 80% for pre-treatment
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 Crusader UV
disinfection system.
