09-09: An Integrated Approach to Water Reuse ManualLimited water resources combined with wastewater discharge concerns have made water reuse a growing focus of the industry. Industrial cooling towers have long been seen as an ideal repository for wastewater because of the large volumes of water necessary for evaporative cooling. However, the use of wastewater as a source of cooling tower makeup water can result in significant corrosion, deposition and biological fouling issues. To address these issues
will also be presented
Actual operating conditions can produce pressure and flow conditions that create significant dynamic piping loads
Opportunities exist to utilize existing instrumentation in some cases along with new measurements to synthesize systems that are effective
This paper will show laboratory test data and detail the effect on fill performance of the following items
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
The recycle and reuse of waste and process water streams can turn potential environmental problem discharge streams into beneficial cooling tower make-up streams
Cooling tower emission rates are usually presented as a Drift Fraction which is defined as the ration of the water exiting the tower as drift divided by the circulating water flow rate
Abstract: American Electric Power's more than 30 years of experience in operating natural draft cooling towers during freezing winter weather conditions is discussed in the paper
emphasizes minimizing the demand
and microbiological control
This detailed monitoring also includes makeup and cooling tower water quality
General introduction to cooling tower drift
