12-16: Green Technologies: Electronic Water Treatment System SuccessfullyThe U. S. Army Corps of Engineers Construction Engineering Research Laboratory and the Air Force Civil Engineer Agency evaluated a high voltage capacitance based water treatment technology in evaporative cooling systems at four military installations in an extended study. The non chemical technology was evaluated for control and prevention of corrosion, scaling and biological fouling in a side by side comparison to standard chemical treatment. Results

Cooling tower blowdown discharge limits for inorganic metals are being lowered more and more

This presents opportunities for scale prevention in heat exchangers by using ultrasound

Grades of Douglas Fir Lumber: recommended stress and non-framework grades and grading rules in application of WCLA grades and Design Data: allowable design stresses (wet operating weight)

Existing concrete cooling tower has been replaced by new steel structure cooling tower

This specification offers recommendations for classification

Cross-corrugated flute angle

This paper is intended to explore the "typical" path that businesses go down when an unexpected cooling tower failure occurs

It has also shown excellent compatibility with other commonly used corrosion inhibitive chemistries

Proper polymer monitoring allows one to understand true demand factors versus other artifacts that might negatively impact control

by the use of experience data

Cooling tower plume formation can be a safety or aesthetic concern
