Track: Commissioning: Optimizing New and Existing Buildings and their Operation
Sponsor: 3.6 Water Treatment, 8.6 Cooling Towers and Evaporative Condensers

Proper water treatment is a key aspect of hydronic system performance and asset life. Commissioning water treatment systems when water is first introduced into a hydronic system provides corrosion protection, extended asset life and prevents other damage due to premature failure. These presentations describe commissioning requirements for various hydronic systems from a water treatment perspective.

1. Commissioning of Your Steam System's Water Treatment Program
Todd Cornwell, Member, AFCO, Raleigh, NC
New steam boilers and hot water boilers need special attention paid to the application of water treatment during the startup/commissioning process. Proper cleaning and passivation during the startup will prevent equipment failures or poor energy performance. Steps to prevent mineral scale and corrosion should be implemented as soon as water is introduced into these systems. This seminar provides guidance (with checklist) on the steps required to prepare the boiler systems for service.

2. Proper Commissioning of Your Cooling System's Water Treatment Program
Dan Weimar, Member, Chem-Aqua, Inc., Irving, TX
New cooling towers, evaporative condensers, fluid coolers, piping and chiller equipment must be commissioned properly to control waterside problems that will reduce equipment life, efficiency, reliability and safety. Proper startup and commissioning is especially important to reduce the potential for white rust corrosion in new cooling water systems containing galvanized metallurgy. This seminar explains the proper commissioning of new or retrofitted cooling water system construction projects and how to avoid costly damages and potential litigation due to uncontrolled water chemistry.

3. Potable Water and Other Indoor Aerosolizing Systems
Tim Keane, Member, Legionella Risk Management Inc., Chalfont, PA
When building water system Legionnaires' disease outbreaks occur no matter how long after construction or renovation, commonly those involved in design and construction are named parties should subsequent litigation occur. And when building water system Legionnaires' disease outbreaks occur within one year of construction or renovation almost always those involved in design and construction are primary named parties should subsequent litigation occur. This seminar covers simple and easy steps to validate that critical commissioning steps of aerosolizing water systems have been completed and are properly documented to insure compliance with ASHRAE 188 and industry best practices.
