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 Microlene strongly recommends that appropriate
pretreatment equip-ment be installed (equipment required 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
ordertoensureef-cientUVpenetration;ifabovethe
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): 5% (Please contact Microlene if water has a UVT that is
less than 80% for pre-treatment recommendations)
You can have your water tested at a by your local dealer or a private analytical
