It was determined the best solution to clean up this large volume chilled water loop, while keeping within a tight budget, would require a 300 gpm Vortisand cross-flow microsand filter that provided submicron filtration and high-quality water.<\/figcaption><\/figure>The new Vortisand unit was installed in early 2010 and after several months of operation proved to be a wise investment for them. Typically, 99 percent removal of particles smaller than 5 micros is achieved after 90 days. Proof that a quality cross-flow microsand submicron filtration system coupled with a comprehensive chemical treatment program was the key to reducing TSS levels.<\/p>\nResults<\/h4>\n During a site visit in April 2014, Jeff Davis stated he has never seen the chilled water this clean since the start-up of the facility in 2000. The TSS issues that previously plagued the entire system never returned. Previously, their 15 heat exchangers had to be cleaned several times per year because of the increased biofilm caused by the suspended solids. \u201cThese heat exchangers have not had to be cleaned since the Vortisand was installed in 2010,\u201d says Davis. Maintaining their design efficiency has improved the bottom line every year with a return on investment of less than 12 months.<\/p>\n","protected":false},"excerpt":{"rendered":"
