Why is there foam in my cooling water?

Foaming in cooling water can occur rapidly, for no obvious reason, and not always predictable by routine system monitoring. Due to the design of evaporative cooling systems, a small amount of foam can be normal. However, in extreme cases, overflowing foam can be cause for alarm. Follow these tips to avoid excessive foaming at your facility.


Cooling Tower Passivation Explained

When an un-passivated galvanized surface is exposed to cycled cooling water, which will typically be oxygen-rich and have an elevated pH, white rust will begin to form. Therefore, a passivation program must be implemented as soon as possible after installation before the system sees cycled tower water under load.
