Overview of Methods and Processes Used in Wastewater …
The process targets the removal of ionic constituents from water or wastewater by reducing their solubility with the aid of counter ions. The process relies on the use of an alkaline agent, for example, lime or caustic soda to raise the pH of the water that causes the solubility of metal ions to decrease and thus precipitate out of the solvent.
