The metals utilized in a cooling tower are susceptible to corrosion in
varying degrees.
This is often true of even the most sophisticated metals although they
can usually withstand deeper excursions into the realm of corrosion
and for longer periods of time than can
the more standard metals.
Circulating water having corrosion characteristics beyond those
anticipated in the towers design requires treatment. This may be due
to high oxygen content, carbon dioxide, low pH or the contact of
dissimilar metals. Where correction of the source of trouble cannot
readily be made various treatment
compounds may be used as inhibitors which act to build and maintain a
protective filmon
the metal parts. Since most water system corrosion occurs as a result
of electrolytic action an increase
in the dissolved solids increases the conductivity and the corrosion
potential. This is
particularly true of the chloride and sulphate ions. Therefore, blow
down is a very useful tool in the
fight against corrosion.
The use of EcoBeam
XL removes and inhibits corrosion. |
