Reverse Osmosis Permeate Stabilization Using Micronized Calcium Carbonate: A potential Alternative to Lime
Paper addresses the inherent problem of Reverse Osmosis (RO) permeate corrositivity to concrete and metal because of its low pH and Langelier Saturation Index. Specific study results are offered relative to the use of micronized calcium carbonate instead of lime for RO permeate stabilization....
Calcite Contactor Use in Desalination Post-Treatment: Technical Update on Current Technology
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...
New Remineralization Process Using Micronized Calcite as a Sustainable Alternative to the Lime-Dosing System
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...
