08-02: Evaluating Your Cooling TowerLow life cost may not be the best method for selecting a cooling tower. Power consumption for pumps and fans, the cost of the basin, piping and electrical equipment, and the choice of tower layout should often be deciding factors. Optimization of tower design conditions related to other equipment such as heat exchangers, condensers or other equipment is discussed.

This paper gives an update of that study which is scheduled to last two years in addition to other water exposure data on pultruded FRP

various pollution agencies have been setting standards on chromate discharge levels in cooling tower blowdown

These new programs were designed to handle low through high hardness

One important aspect of drift performance is the pressure loss characteristic of a drift eliminator and the difference between dry and wet measurements

Improved reliability of cooling tower fan drives is now possible due to advancements in motor technology as evidenced over the last 9 years

The goal of this paper is to detail how the technology has evolved

It involves the use of data generated by a portable fouling

” Such considerations include building codes

This is a brief review of some of the most important of these errors and methods to correct them

the inclusion of chromates in blowdown was recognized as objectionable not only from an ecological standpoint

new data on the effects of halogens on azoles and a new control strategy

Hexavalent chromate can be removed from cooling tower blowdown by either reducing it chemically or electro­chemical1y1 •2 to the trivalent form or by ion exchange and reuse in the system
