Course Description
Natural water includes suspended solids, microorganisms, dissolved salts (ions) and dissolved gases, which cause various problems in systems. In drinking water, suspended solids and microorganisms must give a bad influence on the human health. In cooling water systems and boiler systems, hard soluble matter, such as calcium carbonate, may deposit as a scale on the heat transfer surfaces of heat exchangers and boilers. Then their thermal efficiencies are reduced by scaling. Dissolved oxygen causes corrosion of metals composed of those systems and shortens their service lives. Microorganisms may grow and form slime (biofouling) on heat exchanger tube surfaces, etc., slime adhesion reduces thermal efficiencies of heat exchangers and sometimes causes under-deposit corrosion or microbiologically influenced corrosion (MIC).
Even when water of same quality is used, the kinds and the degrees of problems caused by water vary depending on the usages of water and the operational conditions of systems. Therefore, the application of a suitable water treatment program is inevitable to prevent problems caused by water. The selection of the program must be carefully carried out considering the water quality, usage of water, operational conditions all of these points will discuss in our course.
