Course Description

222-Lime Soda Water Softening Calculations

This course is intended for civil engineers, chemical engineers and environmental engineers. Topics included are calculation of the different types of hardness in a water sample from lab analysis results; conversion among different units for hardness and chemical concentration; information about three lime soda water softening processes (two-stage excess lime softening, split treatment, and selective calcium removal); calculation of the dosages needed for lime, soda ash and carbon dioxide; calculation of daily chemical requirements; and calculation of solids production rates. A sample spreadsheet is included that illustrates the use of a spreadsheet to make some of the calculations discussed in the course.

The overall objective of this course is to provide the attendees with knowledge about hardness in water and the lime soda water softening process for softening water. A more detailed list of learning objectives is included in the course document.

This course will be helpful to me since I am involved with an Upgrade project for a COAG unit. This provides me with somewhat of a working understanding of the equipment
