Technical Committee: 03.06 Water Treatment
CoSponsor: 08.06 Cooling Towers and Evaporative Condensers
Designing a cooling water system to provide proper water treatment is a fundamental aspect of design to provide long term asset management and maintaining efficiency over the life of the system. Current system design for energy efficiency and commissioning for proper operation must be maintained over the life of the equipment and designing and operating the water treatment program to enhance these efforts is necessary. This session provides the engineer, commissioning agent and owner the tools necessary to accomplish these goals.
1 Water Treatment Fundamentals and Performance Metrics
A basic understanding of cooling water treatment fundamentals, treatment strategies and key performance metrics is necessary for designing and operating cooling towers. This presentation provides an overview of water treatment for asset protection for cooling systems and why it's necessary. A brief outline of what tools are available to use by design engineers and owners will be provided, along with key performance metrics that can be incorporated into commissioning documents and operating manuals. Attendees will walk away with an understanding of fundamental aspects of water treatment and what should be expected of a good water treatment program.
2 Control and Monitoring Equipment for Cooling Tower Water Treatment
Owners of evaporative cooling equipment must maintain their equipment to minimize risk, while reducing operating costs and reducing water and energy consumption. Having the proper water treatment control and feed program is a critical part of achieving these goals. This seminar provides an overview of the current industry best practices and look at emerging control and feed opportunities. An easy to use water treatment equipment selection matrix will be reviewed. The content is tailored to engineers and facilities managers involved in designing, retrofitting and operating evaporative cooling systems.
3 Water Treatment for HVAC Specifications
Consulting engineers are often unsure about how prescriptive vs. how performance-based their specifications should be. This presentation describes how one firm approaches this, mainly from a prescriptive standpoint, and what they specify. It covers water analysis and how it relates to both domestic and hydronic systems. Other topics covered are cleaning of piping systems, water treatment for corrosion reduction in hydronic systems, best practices for glycol systems, and a brief synopsis of Legionella suggestions based on ASHRAE Standard 188.
