ASTM WK44798

    New Practice for Standard Practice/Guide for Monitoring Cooling Tower Water Systems to Minimize Energy and Water Use while preventing System Degradation.

    (What is a Work Item?)

    Developed by Subcommittee: D19.03 | Committee D19 | Contact Staff Manager


    1. Scope

    Scope 1.1 By following this monitoring practice, the facility that utilizes cooling water and associated cooling towers for cooling heat exchangers, chillers, heat pumps or other cooling operations will be able to determine if their system is operating within the proper parameters to minimize utility costs, decreasing operation and maintenance costs, increasing system and component life expectancy, verifying proper system performance and reducing the impact on the environment. 1.2 The effectiveness of the monitoring program will also aid development of treatment program refinements to minimize deposit fouling, corrosion and scale formation, along with accomplishing good microbiological control that can reduce microbiologically induced corrosion, fouling and disease. 1.3 The complexity of the monitoring program will need to be adjusted to account for the quality of the makeup water supply(s), cooling system piping and related equipment metallurgies, design features of the types of equipment installed and specific system operating practices. It will also have to take into account the surrounding environment(s) that could impact the performance of the equipment and also exposure of water and exhaust from the cooling tower to operating personnel and the public, and intentional and non-intentional discharges of water to the environment or sent to sewage. 1.4 This standard practice does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

    This standard will be used by any facility that has a cooling tower or cooling water system for heat removal to monitor their cooling water system either by themselves, thru an outside contractor or water treatment supplier.
