Technical Data Sheet CLEANING AND PASSIVATION OF NEW COOLING TOWERS AND OPEN
RECIRCULATING WATER SYSTEMS General
Prior to hydraulic testing or putting a new system into
service, it must be cleaned to remove oil, grease, new pipe mill scale, silts
and organic debris, and general rust accumulations. It is then chemically passivated to inhibit corrosion of the
various metallurgies involved. Since the system may also contain microbiological
contamination, disinfection should be provided prior to allowing any aerosol
emissions from any wet-type heat rejection device (WTHRD), eg cooling towers,
evaporative condensers, etc. Accordingly, the cleaning and disinfection procedures
presented herein also incorporate the procedural concepts and disinfection
guidelines for system start-up as endorsed by The Centers for Disease Control
and Prevention (CDC) and as published in the "1987 Wisconsin
Guidelines" entitled, Control of
Legionella in Cooling Towers, Summary Guidelines. For more, contact CSC Technology for a complete white paper. All Rights Reserved. Do not duplicate
