Chlorine and Bromine Testing In Cooling Tower Systems

Chlorine and bromine based biocides are widely used for microbiological control in cooling tower systems. These halogen compounds form strong oxidizing agents in water, which is how they kill bacteria and other microorganisms. Routine testing is important to confirm effective halogen residuals are maintained. Low residuals can result in poor microbiological control. High residuals can cause corrosion and destroy inhibitors.

How to Calculate Softener Capacity

Water softeners are ion exchange systems designed to remove scale-forming calcium and magnesium ions prior to boiler, cooling, and reverse osmosis systems. The amount of hardness a softener can remove between regenerations is known as the softener capacity and can be expressed either in grains or in gallons. Capacity is important when sizing, configuring, or troubleshooting a softener.
