Q

Describe for the process for Regeneration of Sodium Zeolite Softener

A
  1. Remove the Zeolite Softener from service
  2. Fill it with a solution of Brine (sodium chloride)
  3. The zeolite then absorbs the sodium cations from the brine and discards the calcium and magnesium cations to the brine
  4. The brine is flushed to sewer
  5. The recharged softener is rinsed with water and returned to service
