Cooling Tower Basin Sweeping Effective In Preventing Legionnaires' Disease
Continuous filtration using LAKOS centrifugal separators and cooling tower basin sweeping equipment is an effective method in preventing the growth of Legionella, which can lead to Legionnaires' Disease
ASHRAE Prevention Standards
Guideline 12 in the ASHRAE Handbook points out that..."Keeping the system clean reduces nutrients available for Legionella growth...(and)
The newly published ASHRAE Standard 188 (Risk Management for Legionella) requires building owners to document a plan for regular inspections and maintenance of cooling towers. Section 7.2.3 b clearly states that this plan "shall include requirements and schedule for basin or remote sump cleaning." The three largest cooling manufacturers (BAC, Marley, and Evapco) all offer pre-installed basin sweeping piping configurations for their towers for ease of implementation.
The ASHRAE White Paper titled "Benefits of Cooling Water Filtration" explains even more benefits of Cooling Water filtration.
Prevention Case Study
Saint John's Hospital in Indiana has heard all the horror stories. Concerned with both the risk of Legionnaires' Disease and employee injury common to manually-cleaning cooling towers, the staff at Saint John's installed basin cleaning filtration on their cooling towers. The LAKOS system also made their water treatment more effective, requiring much less chemical use than before the filtration was installed. Says their mechanical team leader, "LAKOS basin sweeping is working extremely well. I can't imagine not having it."
