Slime (a gelatinous organic growth) and algae (a green moss) may
develop in the cooling tower and their presence can interfere with
cooling efficiencies. Proprietary compounds are available from water
treatment companies for the control of slime and /or algae. Chlorine
and chlorine containing compounds are effective algaecides and
slimicides, but excess chlorine can damage wood and other organic
materials of construction. Sometimes chlorine is added intermittently
(shock treatment), and only as frequently as necessary to control
slime and algae. Residual levels of free chlorine should not exceed
one part per million parts of water (1 ppm). Chlorine or chlorine
containing compounds must be added carefully, since very high levels
of chlorine will occur at or near the point of entry into the
circulating water system, causing a localized reduction of pH and
resultant corrosion.
The use of EcoBeam XL helps reduce the biological growth levels in
water and sustained application inhibits it. |
