76-03: Interception and Retention of Cooling Tower Drift on Vegetation Natural Draft Towers

76-03: Interception and Retention of Cooling Tower Drift on Vegetation Natural Draft TowersA key issue concerning environmental impacts from cooling tower operation is rate of interception of drift by soil or vegetation and the efficiency of plants in scavenging drift from the atmosphere. Plant density, retention of drift on foliage, and the subsequent incorporation by foliar absorption of the trace elements will also influence interactions and magnitude of biological effects.

total residual chlorine

dust and insects would surely be scrubbed from the atmosphere by the large roof top cooling tower that was to provide cooling water to a package unit designed to condense water from a nearby commercial building to condition indoor air

including a review of the many chemical additive options for different influents emphasizing simplified chemistry maintenance is discussed

The steam electric industry of this country is predicted to use 40 to 50% of the freshwater run­off

The findings of this study constitute a major step forward for the cooling technologies industry

Nalco was awarded DOE grant to develop a cost-effective integrated solution (chemical and physical) for the use of impaired water and maximize the cycles of concentration

This paper reviews this situation in view of the continuing difficulty in obtaining proper penetration of the recommended salt treatments

The new laboratory consists of hall laboratory and exterior experimental facilities

Samples of the cooling water were collected

Two primary characteristics were studied: threshold inhibition

To demonstrate this new corrosion inhibitors performance benefits

Suspended solids and phosphorous removal at levels greater than 90% is achieved
