64-04: Chemical Cleaning of the Water Side of Process Equipment Environmental ImpactA paper presented to the Cooling Tower Institute, New York City, on June 17, 1964, by W. E. Zimmie. Process Equipment is shut down for periodic cleaning due to: 1)Hard Scale formation 2)Biological growth 3)Mud and Sedimentation.
Fractures in cooling water system components can lead to costly failures
Because of the aggressive process and environmental exposure conditions
The ratio was found to vary from 60% to 90% during typical operating conditions
Protection of water as a natural resource requires that its quality and availability be carefully regulated
The failed or cracked columns were attributed to misuse of fiberglass bearing pads or poor construction procedures
A low system oxidation-reduction potential (ORP) is desirable to minimize corrosion in recirculating cooling systems
especially in those semi-arid to arid regions where water conservation is at an absolute premium
These floculant precipitates stabilize the water films on
counting planktonic microorganisms
The current status of the EPRI Cooling Tower Performance Test Facility Project
it is desirable that losses in fan system performance due to the drift eliminators be minimized
and the cooling water was recycled through a sidestream softener was studied
