Cooling Water Problems and Solutions

COURSE NO: M05-009
Cooling Water Problems and Solutions
Course Highlights

This online engineering PDH course presents an overview of common chemical treatment program that may be required to maintain cooling water systems in good operating condition.  Reasons and means are discussed for controlling scale, deposition, corrosion, and biological fouling. The discussion also covers the information on chemicals used for control, and methods available to permit operation within the limits.


The three primary reasons that the cooling water treatment may be required are to control corrosion, scale formation, and the growth of biological agents. Any of these problems - or more usually a combination of them - can cause a loss of efficiency, shorten equipment life and push up operating costs. Imagine the large amounts of dollars lost when insufficient cooling suddenly curtails operations of process equipment.


This 5 PDH online course is applicable to all engineers and designers involved in power plants, oil and gas, chemical and petrochemical process facilities, refineries, industrial plants and HVAC systems in commercial buildings.
