Cooling Water Treatment to Improve Efficiency, Operations
Mexel USA and the University of Michigan have signed an agreement to perform a 12-month demonstration of the Mexel 432/0 cooling water treatment on a system servicing buildings on the main campus.
The demonstration project will begin the end of January 2015 applying an emulsion recently approved by the EPA.
During the demonstration, small amounts of Mexel 432/0 will be injected into recirculating cooling tower water to address a number of fouling problems that can adversely affect operations and energy efficiency. University engineers will closely monitor system operations using a number of established performance indicators. These results will be analyzed and compared, along with economic and environmental factors, to historical data for an overall evaluation of the project.
The University of Michigan’s energy services include the central power plant, which generates and processes four main services to the University Central and Medical Campuses; steam, electricity, compressed air and domestic hot water, and energy systems for heating and cooling facilities throughout the university that include more than 100 cooling towers.
US commercial buildings can collectively save up to 28 billion gallons of water annually by using a suit of tools produced by AT&T and Environmental Defense Fund, the organizations say.
For example, buildings with cooling towers typically use 28 percent of their daily water for cooling. AT&T and EDF say the toolkit can help these building reduce that water demand by 14 percent to 40 percent.
