This paper will focus on the use of calcite beds for post treatment of soft waters. A comparison of the benefits of calcite beds over lime dosing systems will be shared. Desalinated waters require post treatment to adjust the pH, alkalinity and hardness suitable for the intended use and applicable standards. Conventional water remineralization ca...

Desalinated and naturally soft water is corrosive because of its low pH value and lack of minerals, and therefore requires post-treatment for water stabilization and corrosion control. Conventional water remineralization can be achieved either by calcite contactors or lime dosing systems. Both of these techniques present some drawbacks for large de...

Desal permeate and naturally soft water are low in pH and mineral content and buffer capacity. As a result, these waters are considered unstable, aggressive to metals, and can be detrimental to personal health. The re-introduction of minerals, or remineralization, is an essential post-treatment process that makes the water suitable for discharge in...
