75-10: Operating Experience with the Electro-Chemical Chromate Removal Unit Testing

75-10: Operating Experience with the Electro-Chemical Chromate Removal Unit TestingIn many cooling tower systems, chromate treatment for corrosion control is preferred. The advent of environmental regulations and restrictions has made it necessary to consider carefully the disposition of blowdown water containing chromate and in many cases zinc, both of which are undesirable pollutants if allowed to enter receiving waters.

The standard Cooling Tower Shade is a dark gray which at Strongwell is known as slate gray

it is important to operate at a speed sufficiently lower than the drive shaft's natural frequency to prevent destructive vibration

and improved appearance

it was a bold decision

The consumptive use of water is of con­cern to us -- for plants that use cooling towers (the practical alternate method to using stream or reservoir water) use more (consumptive) water per kilowatt hour generated than do plants which are able to circulate their cooling water in lakes

the risers close after flow disturbances

a method is outlined for documenting inspection results and the reporting process

This change has occurred due to concern about waste heat disposal and thermal pollution effects caused by traditional once through systems

Film fill fouling is an important problem in modern power plant and industrial process cooling

A method for evaluating products is offered
