Please note that the flow rate capacities specified below are based on a UV dose of 40 mJ/cm2 at 95% UV transmittance (UVT). UV transmittance is a measure of the clarity of your water and the ability to pass UV light through it. 95% UVT should be considered rather ideal. If your UVT is less than 95% or you are unsure of your UV transmittance (i.e. it has not been tested), we recommend that you choose a UV unit with roughly 2 times the flow rate capacity that you need (this equates to a UVT level of about 70-75%). This will ensure that your water will be safely disinfected in the event that your UV transmittance is less than optimal. If your UVT is known to be less than 75% or your source water is highly coloured or cloudy, please call us for pre-treatment and sizing assistance (toll free 1-866-376-2690).
