Warninga regular basis to minimize the growth of bacteria, including Legio-
nella Pneumophila, to avoid the risk of sickness or death. Service personnel must wear proper personal protective equipment during decontamination. Do NOT attempt any service unless the fan motor is locked out.
Operators of evaporative cooling equipment, such as water cooling tow- ers, should follow maintenance programs which will reduce to an abso- lute 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. See Tower Startup instructions on page 12.
The visual inspection should take place at least once a week during the operating season. The periodic flushing and cleaning should be done be- fore and after each cooling season, but in any event at least twice a year. The louvers, drift eliminators, and easily accessible fill surfaces should be flushed by use of a
suspended solids concentrations, thus increasing the effectiveness of the water treatment program. See Tower Startup instructions on page 12.
Blowdown:
A cooling tower cools water by continuously causing a portion of it to evaporate. Although the water lost by evaporation is replenished by the makeup system, it exits the tower as pure
In order to achieve water quality which is acceptable to the cooling tower (as well as the remainder of your circulating water system), the selected water treatment company must work from a relatively constant level of
