Cooling Tower Cleaning
Any evaporative-type cooling tower must be thoroughly cleaned
on a regular basis to minimize the growth of bacteria, including
Legionella Pneumophilla, to avoid the risk of sickness or death.
Service personnel must wear proper personal protective equip-
ment during decontamination. Do NOT attempt any service unless
the fan motor is locked out.
Operators of evaporative cooling equipment, such as water cooling towers,
should follow maintenance programs which will reduce to an absolute minimum
the opportunity for bacteriological contamination. Public Health Service officials
have recommended that “good housekeeping” procedures be followed, such
as: regular inspections for concentrations of dirt, scale, and algae; periodic
flushing and cleaning; and the following of a complete water treatment program
including biocidal treatment.
Visual inspection should take place at least once a week during the operating
season. Periodic flushing and cleaning should be done at least twice a year.
Nozzles should be checked for clogging. Drift eliminators, and easily acces-
sible fill surfaces should be cleaned by use of a moderate-pressure water
nozzle, being careful not to cause physical damage. A reliable water treatment
program should be installed and maintained.
