On July 25, 2018 Masters’ Academy toured Appleton’s Water Treatment facility. The City of Appleton’s Director of Utilities, Chris Shaw, provided an overview of their new Ultraviolet (UV) water treatment system and how it has significantly reduced their operating costs.
Appleton’s UV project is a great example of how this technology can be used to improve overall water quality while simultaneously reducing the operating costs associated with labor, materials, and electrical energy. It is worth noting that water quality went from 99.9% parasite deactivation to 99.9999%, making this a true win-win for Appleton and other cities serviced by this water utility.
The City of Appleton invested approximately $5,000,000 into this project and is now saving more than a $1,000,000/year (see chart below). That’s a 20% simple return on investment. Pretty Impressive!
The key to this cost reduction initiative was the installation of a series of Calgon Carbon UV water treatment reactors. These UV units replaced an existing, energy and maintenance intensive, membrane filtering system. The original membrane filters required over 400 hp to operate. Calgon Carbon has been a leader in the development and application of UV treatment over the past 18 years.
