72-04: Condition of Preservative Treated Cooling Tower Slats After 10-Year Water Reuse

72-04: Condition of Preservative Treated Cooling Tower Slats After 10-Year Water ReuseSlats of four species were treated with six preservatives to study their effectiveness in controlling typical brown or white rot by the Basidiomycetes fungi and soft rot by the ascomycetes and fungi imperfecti. Additives to water were used to control chemical deterioration and corrosion and growth of contaminants such as algae and slime.

together with the fact that the majority of cooling towers are made of wood

reduce water needs

The cooling towers in plants of this type are generally of crossflow de­sign

Microprocessor controllers can provide inexpensive energy conservation control at a fraction of the cost of conventional AC-DC innoverters

Growing emphasis

Major changes were implemented to the traditional microbiological control

The water used for the cooling may be obtained from ground waters

repairs to vibration detection systems and significant changes in preventative maintenance routines

Microbiological fouling was controlled with chlorination and non-oxidizing biocide program

operation and the instrumentation used to capture the fundamental thermodynamic data require money

and indicate that significant economic advantages can be realized
