Industrial cooling water systems are key enablers of unit processes. Maximizing cooling system performance serves to realize primary business goals such as production throughput and yield, energy and water conservation, capital asset preservation, environmental compliance and the protection of human health. The management of corrosion is inextricably linked to successful control of scale and deposits, as well as microbiological activity.

Throughout the past 30 years, industry has benefited from a steady progression of developments technological advancements in the automation and control of critical water system parameters. Today, measurement of all three crucial elements of effective cooling water treatment (i.e. corrosion, deposition and microbiological activity) is possible with a single instrument platform that is reliable and cost-effective. In addition, that same platform is capable of controlling critical variables for corrosion and deposit control that takes full advantage of these new measurement capabilities.

This paper discusses the most recent and complimentary developments in automation and process control technologies, in both on-line and off-line modes, and the convergence of their development with the changing needs and challenges of operators of industrial cooling water systems. Case reviews of real-world field applications of on-line technologies in practical, every-day situations also are presented.
