An Introduction to Chemical Cleaning of Industrial Water Systems

COURSE NO: H03-003
PDH CREDIT: 3
An Introduction to Chemical Cleaning of Industrial Water Systems
Course Highlights

This online engineering PDH course will introduce you to methods for cleaning industrial water systems with chemicals. You will learn about pre-operational cleaning which is performed to prepare water-contacted metal surfaces to receive chemical treatment to provide protection from scale, corrosion and microbiological growth.  You will also learn about remedial cleaning to restore water systems that have been fouled with scale, corrosion products and microbiological growth due to inadequate or ineffective water treatment.  Examples of industrial water systems for which chemical cleaning are applicable are boilers, heat exchangers, cooling towers, and chillers.

 

Maintenance of an effective water treatment program is essential to minimize scale and corrosion problems in industrial water systems; however, scale and deposits will often form and require remedial cleaning. If not removed, these scale and water-caused deposits may impact the safety of operations personnel, interfere with heat transfer, and cause excessive damage to, or destruction of, the water-using equipment.

 

This 3 PDH online course is intended for industrial, chemical and mechanical engineers, as well as, maintenance personnel and construction professionals interested in learning about the use of chemicals for cleaning industrial water systems and equipment such as boilers, heat exchangers, cooling towers and chillers.

Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Learning about pre-operational cleaning of new industrial water-using systems and equipment
  • Learning about remedial cleaning of industrial water systems and equipment to restore them to optimal operating condition
  • Learning about chemical cleaning methods that have largely superseded mechanical cleaning methods
  • Learning about chemicals used for chemical treatment of industrial water systems
  • Learning about the use of hydrochloric acid to remove carbonates scale with lesser amounts of phosphates, sulfates and silicates
  • Learning about hydrochloric acid's limitations where stainless or galvanized steel is part of the system
  • Learning about the use of sulfamic acid to remove scale from metal surfaces
  • Learning about the importance of isolating equipment to be cleaned from other parts of the system using valves, rubber blankets, wooden bulkheads with seals, inflatable nylon or rubber bags, rubber sponge-covered plugs, or blind flanges and steel plates with rubber seals
  • Learning about the recirculating cleaning process for boilers
  • Learning about a circulating method for descaling smaller equipment that does not require heating
  • Learning about the fill and soak method of chemical cleaning
