Microbiological problems in cooling water systems cost businesses billions of dollars each year due to high energy costs, production losses, unscheduled maintenance, and replacement of corroded parts. Poor microbiological control can also lead to unsafe operating conditions, such as contamination by the bacterium that causes Legionnaires’ disease. While this article focuses on biocide contact time, there are many factors to consider when choosing the correct biocide, including:
Water treatment makes good economic sense. An effective water treatment program helps maximize the life, efficiency, reliability, and safety of boiler and cooling systems and minimizes total operating costs. Water treatment only represents a small percentage of the costs associated with operating a boiler or cooling system. However, this small percentage dramatically influences the total operating costs (fuel, water, maintenance, and labor).
What We Can Learn from Flint
On a recent episode of the Public Broadcasting Systems’ Frontline “Flint’s Deadly Water,” investigative reporters looked deeply at the city of Flint from 2014 to now in hopes of identifying the true causes of the water crisis and the cause of the many deaths. As an outsider, we immediately associate Flint with a lead crisis, which undoubtedly remains an issue. However, Frontline finally dives deeper and states that Legionnaires Disease is the true public health crisis that happened in Flint. Below is a summary of the research they did and their findings.
Cooling towers are a critical component in many water systems, providing comfort or process cooling across a broad spectrum of technologies and applications. Cooling towers vary greatly in design and footprint, but all have the main goal: to provide removal of waste heat from processes or building systems. Control parameters are critical to maintaining any cooling system to improve water and energy efficiency, maximize equipment life expectancy, reduce hazards, and minimize downtime.
Key Terms for Water Treatment Novices
Water treatment specialists can forget that their clients may not understand the technical terms used in our industry. The language of microbiological control can be particularly confusing. To help establish a common working vocabulary, it’s important to define some key terms. Let’s get started!
