Dominion Virginia Power Corporate Office Building

In January of 1997, Clean Streams™ LLC replaced a traditional chemical treatment program at a major utility corporate office building with an ozone water treatment system that centered on the Clean Streams™ Ozone Transfer Process.  The cooling towers, located on the roof of a 22 story building, were experiencing fouling of the fill that restricted air flow and required quarterly cleaning to prevent reduced cooling efficiency.

The 22-story building has two 800-ton chillers for HVAC and one 600-ton chiller dedicated to the computers in the billing department.  Two BAC cross flow towers and one Marley cross flow tower are connected via a common header.  All towers were experiencing microbiological fouling.
