    The quartz sleeve is an important part of the UV water treatment system. It protects the UV lamp from coming in contact with the water while allowing the UV light to permeate the water. Minerals from the water will build up on the sleeve over time causing the sleeve to become cloudy not allowing the UV light to permeate the water as effectively. How quickly the minerals build up on the sleeve will vary depending on your water hardness, and if you have hardness of over 7 gpg you should install a water softener to treat the water before your UV system. Once the mineral layer on the quartz sleeve cannot be removed via cleaning, or the sleeve cracks or breaks it's time to get a replacement. The US Water Filters USWF-350059 is a replacement for VIQUA 602976 for use in the VIQUA J/J+/K/K+, Pro 30, Pro 50, S80, SM80, & SV50 series of ultraviolet water treatment systems. All quartz sleeves come with 2 replacement o-rings.

    How Does UV Disinfection Work?

    Ultraviolet light water treatment systems utilize special UV lamps that emit UV light at a wavelength that damages microorganisms cellular function neutralizing the microorganisms DNA and their ability to function and reproduce. Because the microorganisms cannot replicate they cannot infect other organisms they come in contact with. This disinfects the water without the need for chemicals which need to be precisely administered and carefully monitored. Once installed the UV lamp runs 24/7 constantly disinfecting the water that travels through it and only requires minimal annual maintenance to keep running.

    Because UV light only travels in a straight line any shadow or obstruction will reduce its efficiency. This means it is important to filter your water before UV treatment to make sure suspended particles like silt and sand are removed. Hardness minerals can also build up on the quartz sleeve which may require cleaning during lamp changes, however if the incoming water is hard enough a water softener is also recommended for pretreatment to reduce this buildup.

    Naturally sourced water should be professionally tested and treated before it is used for drinking, bathing, filling swimming and paddling pools, food preparation or cooking. A number of water treatment systems can be used to remove microbiological contaminants that may cause illness. Ultraviolet light disinfection is an effective, reliable, environmentally friendly and chemical free water treatment system that can be used to disinfect water from most forms of microbiological contamination.
