Breakthrough Made in Chemical-Free Maintenance of Cooling Tower/Condenser Water

March 12, 2000
STONEHAM, Mass.--A chemical-free breakthrough in cooling tower and condenser water treatment systems has been announced by the A.W. Chesterton Company. The VRTX (Vortex) System eliminates the need for chemical treatment in cooling towers and related systems. Cooling towers use water to remove heat from large manufacturing and processing facilities. By design and use, they are one of the largest users of water and the source of a major portion of industrial wastewater. VRTX uses a patented technology that mechanically removes scale deposits, algae and slime from the water. Traditionally, to eliminate scale build-up, most cooling towers throughout industry use chemicals that are increasingly hazardous to the environment and adversely affect wastewater treatment facilities. The A. W. Chesterton Company, based in Stoneham, Mass., also announced the launch of its new VRTX Technologies Division in San Antonio, Texas, to manufacture, market and service the patented VRTX System. "The EPA continues to place restrictions on the use of chemicals in cooling towers," said Robert Kelsey, Vice President/General Manager of VRTX Technologies. "With the Chesterton VRTX System, we've achieved a chemical-free solution in cooling tower treatment and can offer a viable cost effective alternative to conventional methods of chemical treatment while dramatically reducing water consumption and discharge (no "blow-down", or sewage and disposal issues). "This has numerous environmental and economic benefits," Kelsey pointed out. "In addition to attacking scale build-up, these benefits include corrosion reduction, decreased maintenance and energy costs and improved operating efficiency." As a result of "predictable, reliable and consistent" benefits, the VRTX System recently was named "Product of the Year" by Plant Engineering magazine. The VRTX System contains a vacuum lens inside the chamber that strips out carbon dioxide and other dissolved gases, thereby accelerating the formation of non-sticking calcium carbonate. This, combined with the high shear forces in the chamber, alters the chemical state of dissolved calcium forming calcium carbonate, which then precipitates out. The removal of gases combines with the increased pH to control corrosion. The water to be treated is pumped directly from the holding basin. Nothing is added to the water and no toxic materials or gases are released. The VRTX System has been in use at numerous cooling tower/condenser installations during the past several years as beta sites and as customers. The system requires no chemicals to purchase, far less water used and energy and maintenance attention savings. Further, in some states, municipal water authorities reimburse companies up to 50% of the purchase price of water savings devices such as the VRTX System.SOURCE: A.W. Chesterton Co.
