Lime Softening Calc Software?
(OP)
Hello:
Would anyone be able to recommend a source for hot lime softener modeling software to help calculate lime, soda ash and MgO feed rates for treatment of a given water? Perhaps just an Excel spreadsheet program to share and perhaps build upon.
Many thanks.//

RE: Lime Softening Calc Software?
Operation of a HLS can be a nightmare in addition to the maintenance. I devised a plan to take this single unit out of service for cleaning every 6 months. Cleaning time was scheduled for approximately 24 hours. Basically it was a wash down to remove accumulated sludge in all compartments and sight glasses. It is also necessary to limit flow swings to no more than 50 gpm per hour to prevent serious upsets. Perhaps I'm preaching to the choir here.
I'll search my computer discs and will let you know if I found the spread sheet. Give me a few days and I'll get back to you.

Found what I looked for, very surprising! It's just a simple spread sheet showing # of hydrated lime and Magox to be used with a varying alkalinty and Mg content of the raw water. You just type in the numbers and the spread sheet calculates the chemical requirements. I also included chemical costs to make comparisons but the chemical price figures will need adjusted as they are very old. I also found another spread sheet that will calculate the GPM of lime feed, for different lime slurry concentrations, based on water flow to the HLS and the alkalinity and Mg hardness of the raw water.

I was wondering if I could possibly have a gander at that spreadsheet. I'm new to hot lime softening as my past has been in biological treatment and I could use any help you could provide.
Thanks,
