Ultraviolet Tech Improves Water Treatment

Sierra Nevada Brewing Company Uses Aquionics' UV-C Technology forBreaking Down Unwanted By-products from the Water

When it comes to ensuring a consistent beer taste, theSierra Nevada Brewing Companyin Chico, CA uses Aquionics'UV technology in its process. UV-C to be precise. The UV-C part of the UV spectrum is highly effective at breaking down unwanted by-products from the water purification process, ensuring optimal beer taste at all times.

"The taste of our beer is a key selling point," comments Aaron Porter, Sierra's Plant Services Supervisor. "Water is the main ingredient of beer and, even though we have a great water source, by law it needs to be chlorinated prior to use. That's where the Aquionics UV technology plays its part - UV has proved to be highly effective at destroying any residual chlorine remaining in the process post-treatment. In this way it ensures the consistent taste of our beer. We now have three Aquionics units preforming this role.

In addition to these two applications, the brewery is planning to use UV as part of its water reclamation project, whereby water used for cleaning bottles and kegs will be disinfected and reused for landscape irrigation.

UV also has many other uses in the brewing, beverage and process industries, including the disinfection of municipal or private water supplies, de-aerated liquor (part of the high-gravity brewing process), clean-in-place (CIP) water, sugar syrups, sweeteners and yeast preparation areas.

UV systems are easy to install, with minimum disruption to the plant. They need very little maintenance, the only requirement being replacement of the UV lamps every 12-18 months, depending on use. This is a simple operation that takes only a few minutes and can be carried out by general maintenance staff.
