EPA Approves Broader Application of Cooling Water Technology

EPA approves Mexel 432/0 water treatment technology to address biofouling

Owners and operators of large once-through and recirculating cooling water systems now have a new tool to address efficiency losses and fouling in their water circuits and heat exchangers. The U.S. Environmental Protection Agency (EPA) approved these expanded uses for the Mexel 432/0 water treatment technology to address biofouling, in addition to its capabilities to combat corrosion, scale and sedimentation. An emulsion injected directly into the water for short periods each day creates a protective coating on wetted surfaces to prevent problems before they develop, maintain high cleanliness factors, and promote sustainable plant operations. 

“We are gratified that EPA has recognized Mexel 432/0 as an environmentally viable product to address the persistent fouling problems encountered in many plants.  With intense competition in the wholesale generation markets, the ability to improve performance by as little as 0.5% to 1.0% can have a significant impact on dispatch,” said Mary Wolter Glass, president of Arlington, Va.-based Mexel USA LLC. 

EPA’s risk assessment also found that Mexel 432/0 poses no “higher risks to aquatic organisms than alternative chemical substances that could be used as biofoulants."  For facilities with existing National Pollutant Discharge Elimination System surface water discharge permits, the use of this product should be equally acceptable and pose no “increased regulatory burden for permit writers." 

This expands Mexel USA’s ability to supply utility, industrial and institutional plants with its products. These green solutions work equally well in large water-cooling systems such as power and industrial plants, as well as smaller commercial, institutional, government, school and office facilities. The environmental performance, compact size, simplicity and safety for workers and the public make it valuable for water treatment.
