What Is Ultraviolet (UV) Water Treatment?

Ultraviolet (UV) light is used in many commercial and industrial water filtration applications where the feedwater, or raw water, is subject to contamination by microorganisms. UV light is able to penetrate the cell walls of microorganisms, disrupting the cells in such a way that they are prevented from replicating. Microorganisms that are unable to replicate are unable to cause human infection or create damaging situations for manufactured products and/or processing equipment. UV water filtration should not be used as your only source of filtration, however, as it does not remove heavy metals or filter the microorganisms from the water.

What Does a UV System Consist of?

A typical UV system has at least two pre-filters and a UV light inside a bulb sleeve. The pre-filters will remove debris (solids), as UV water treatment is less effective when these solids are present. The UV bulb sleeve is located inside of a tube, and the water runs through the tube and around the sleeve. These are often located after the point of entry.

In the example above, the pump pushes water through a sediment filter and charcoal filter to remove debris. The filters enable the UV light to effectively disinfect water that is as clear as possible.

What Kind of UV Light Does My System Need?

Your UV system needs to provide an intensity or “fluence” strong enough to inactivate the harmful organisms found in raw water. The “fluence” is a combination of the strength of the light, the distance the light travels through the water, and the speed at which the water travels past the light. The intensity you need is 40mJ/cm² (milli-Joules per square centimeter) or 40,000 µWsec/cm² (micro-watt seconds per square centimeter). In order to ensure that disinfection is taking place effectively and efficiently, it is important to regulate the water type and flow to match the light intensity and specifications provided by the manufacturer/provider. When you choose Complete Water Solutions for assistance with the installation and/or maintenance of your UV water treatment system, all of the technical specifications will be taken care of! We will work with you and provide documentation so you know what levels your system will need to be operating at for maximum efficiency and effectiveness. We also offer a protective coating to keep shards of glass out of your water system in the event that the sleeve or bulb shatters (see video below)!
