CLEVELAND, OHIO—Green Lodging News has added a new case study to its Vendor Case Studies section. The case study focuses on the Mandarin Oriental, Washington, D.C., and how Sonitec’s Vortisand filter was able to solve its cooling tower sludge problem. Massive amounts of the nasty stuff were detected in the chiller tubes, and the 12-inch system feeder pipe as well. The filtering apparatus on line proved ineffective at combating the problem, prompting management to seek out expert consultation.
Patrick Payne of Boland Trane teamed up with Denny Alexander of Armstrong Filtration (provider of cost-effective filtration solutions based in Winchester, Va.) to conduct a scientific examination of the hotel’s cooling water system. Both companies have been bringing innovative products and services to their clients since the early 1960s.
“We collected water samples from the hotel’s cooling water system and forwarded them to an independent laboratory for laser particle distribution testing,” recalls Denny Alexander. “This lab analysis determines the micron size dispersion and dirt load concentration per each micron size from 100 to 0.45 sub micron range. The results were quite revealing. Roughly 95 percent of the particles were under 20 microns. The findings narrowed the field, as far as filtration solutions went. Many types of filtration systems previously considered were automatically ruled out. The only one that met all the criteria we were looking for turned out to be Sonitec’s Vortisand filter.”
