64-04: Chemical Cleaning of the Water Side of Process Equipment Environmental Impact

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
