Sterilight S8Q-PA Ultraviolet (UV) Sterilizer

The Sterilight S8Q-PA Ultraviolet (UV) water sterilizer is a popular and economical choice for less demanding (smaller) whole house water purification to kill bacteria (including coliform and e.coli), viruses, cryptosporidium, giardia, and a wide range of other microbioogical contaminants, where the maximum required flow rate is not greater than 10.0 gallons per minute (GPM) or 37.9 litres per minute (LPM).

The Sterilight S8Q-PA (part of Sterilights's Silver Series) includes many popular convenience features including a visual "lamp on" indicator light, audible lamp failure alarm, and LED display that indicates lamp life remaining and total controller run time. The S8Q-PA also features a stainless steel reactor chamber, a fire-polished domed quartz sleeve, and Sterilights' popular Sterilume™-EX coated low pressure germicidal UV lamp which can be easily changed without interrupting the water flow. It also incorporates Sterilight's Silver controller which automatically senses line voltage between 100 and 240 volts for consistent UV output and performance in varying electrical operating conditions.

This model does NOT include a UV intensity monitor and it CANNOT be connected to an emergency solenoid shut-off valve. If either of these features appeal to you, we recommend that you consider the Sterilight Silver Plus Series UV Sterilizers.

Pre-treatment Requirements:

All UV sterilizers required sediment pre-filtration to reduce or eliminate the possibility that a targeted contaminant could "hide" behind a sediment particle in the "shadow" of the UV light and therefore not receive a full dose of UV light. Accordingly, the manufacturer strongly recommends sediment pre-filtration down to a level of 5 microns or smaller.

Water exceeding 120 ppm in hardness (7 grains per gallon) should be softened to reduce the risk that hard water mineral scale will build-up on the UV sleeve thereby reducing UV light distribution into the UV chamber. Similarly, iron levels exceeding 0.3 ppm or manganese levels exceeding 0.05 ppm should also be treated to prevent staining of the UV sleeve.

Elevated levels of certain other contaminants, such as tannins, can cause a reduction in UV transmittance (the ability of the water to transmit UV light). If the UV transmittance (UVT) of your water is less than 75% after the above-mentioned pre-treatment, activated carbon filtration may be desirable to improve UV transmittance. The majority of deep wells have a UVT of 85% or greater. If your UVT is unknown, select a model with a higher flow rate capacity then you feel you will really require (this will provide a higher UV dose at your desired flow rate), or add an activated carbon pre-filter to your system. We recommend the following pre-filter equipment:

*Note: Maximum recommended flow rates based on 95% UV transmittance. Actual dosage depends on flow rate, water quality, and maintenance (cleaning ov UV sleeve). UV dosage will be lower when the UV transmittance capacity of the water drops below 95% - if in doubt, select a model rated for a higher flow rate than you actually require. We recommend a UV dose of 40 mJ/cm2.
