Cooling Water Systems Microbiological Activity and Control in Cooling Water Systems
Doug McIlwaine, ChemTreat​

1:45 p.m.

Water Safety: Legionella Control Strategies
John Cioffi, NALCO Water, An Ecolab Company
Recent trends have increased public awareness that waterborne pathogens can be associated with water systems and that these water systems must be managed to reduce the risk of a health hazard associated with cooling water and domestic water systems. More specifically, questions around the subject of Legionella are being raised. This presentation will provide an overview of basic Legionella facts, the market events that led to the creation of American Society of Heating, Refrigerating and Air-Conditioning Engineers Standard 188, and the move toward the convergence of a “health-based” treatment strategy.

2:30 p.m. 

Break

2:45 p.m.

Cooling Tower TDS and PM10 Emission Limits: Considerations for Achieving Compliance
Michael Lacourt, Ramboll
Cooling towers are a source of emissions of particulate matter less than 10 micron diameter (PM10) to air in the iron and steel industry. These emissions are directly related to the total dissolved solids (TDS) in the recirculating cooling tower water. Emissions calculations, values for PM10 and TDS in typical industrial applications, regulatory considerations, and mitigation techniques including control strategies (e.g., on-line TDS meters and automated blowdown) and technologies (e.g., drift eliminators) will be discussed.

3:30 p.m.

Regulatory Flexibility Mechanism in NPDES Permitting
Gary Amendola, Amendola Engineering Inc.
Review of regulatory flexibility provided by the iron and steel ELGs, the NPDES permit regulations and state water quality standards. The objective is to obtain appropriate technology-based and water quality–based effluent limits on a site-specific basis.

4 p.m.

Break

4:15 p.m.

Energy Efficiency Improvements in a Cooling Water Circuit- Case Study
Jerry Penland, Hatch
This presentation discusses a case study in which a steel manufacturer requested a study on its hood cooling system to determine if there was sufficient capacity to cool additional equipment. It was determined that additional cooling was available and that significant energy savings were available if several changes were made to the system. A three-fold strategy is discussed in detail. Findings in this study may be applicable to your cooling water systems
