Advantages to use limestone

Published on by

Hello, I want to know about advantages to use limestone instead of lime for post-treatment of desalinated water? I am interested in knowing the experiences of group members on this topic.

  1. Hi Aing: Limestone allows achieving the same alkalinity and hardness goals at lower costs and with lower finished water turbidity. However, high quality limestone is not always readily available near the location of a given desalination project, which limits its use.
