These Excel spreadsheets will make calculations for water softening, using lime and caustic soda or just caustic soda, including dosages and daily requirements for lime (if used), caustic soda and carbon dioxide, as well as estimates of daily solids production.  Such calculations are also available for lime soda softening with  i) the two stage, excess lime process,  ii) the single stage, selective calcium process, and iii) the split treatment process.  Calculations are in U.S. units.  NOTE:  This workbook includes all of the worksheets in the Lime Soda Water Softening workbook described below, plus worksheets for softening with lime and caustic soda and for softening with only caustic soda.

This Excel Spreadsheet calculates the head loss and pressure drop for liquid flow through a packed bed, based on user input values for the flow rate through the bed, bed dimensions, packing properties, and liquid density and viscosity.  It also creates a plot of pressure drop vs flow rate through the bed for a series of user entered values for flow rate.  The calculations are done using U.S. units
