84-10: Cooling Tower Wood Decay Identification, Current Incidence, and Control Environmental Impact

84-10: Cooling Tower Wood Decay Identification, Current Incidence, and Control Environmental ImpactHow to identify decay in a wood cooling tower. Where it occurs, what it looks like, and how to determine if it is in your tower. A review of the incidence in Douglas fir "treated" lumber, and how it can be controlled before and after the tower is assembled.

plant processes

A code to develop standardized test procedures and evaluation techniques also designed to provide a uniform method to compare relative water treatment program performance in a cooling water system

cycles of concentration

This paper will show laboratory test data and detail the effect on fill performance of the following items

Power plant condenser tube represents a significant metallic surface area exposed to a wide compositional range of cooling waters

the water often becomes polluted

Cyclonic Filtration has transformed itself to new levels of performance

These standards range from complete elimination of chromates to low effluent levels requiring the installation of elaborate and costly treatment systems which reduce and precipi­tate the chrome

more stringent restrictions on permitted discharge consents and/or increased cost or reduced availability of good quality water have emerged or developed in some parts of the world

BPA has designed and built the nation's largest network of long-distance transmission lines

It focuses in particular on the vibration of the fan stack at blade passing frequency
