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 equipments.

A very high percentage of people responsible for operation and maintenance of cooling water systems have little or no knowledge of water technology and are therefore totally reliant on specialist water treatment companies to provide up to date cost-efficient water treatment programs suitable for their particular plants.

This five hour 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.

It 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.

Learning Objectives

Upon completion of this course, participants will be able to:

• Identify the critical parameters applicable to cooling water treatment, including conductivity, TDS, pH, alkalinity, and the saturation index.
• Explain the relationship between cycles of concentration and blowdown.
• Describe the factors responsible for scale and corrosion.
• Distinguish among the types of scale and the methods used to minimize scale formation.
• Identify physical water-treatment methods, including softeners, dealkalizers, ion exchangers, filtration, and electronic descaling equipment.
• Describe the types of corrosion and the control techniques used to mitigate corrosion.
• Explain the principles of cathodic protection.
• Classify types of biological fouling and describe treatment methods, including oxidizing and nonoxidizing biocides.
• Compare five application methods for dosing chemicals, including their benefits and limitations.
• Distinguish among four types of corrosion inhibitors: anodic, cathodic, mixed, and adsorption inhibitors.
• Identify the chemical feed equipment used for closed and open cooling water systems.
• Describe the control sensors and monitoring devices used in cooling water treatment.
