1. Many water treatment equipment suppliers can provide lime softening equipment.  My company, Evoqua Water Technologies provides various models depending on flow and requirements. A lime softener is basically a clarifier that uses lime or caustic to raise pH and add hydroxyl to precipitate calcium carbonate and magnesium hydroxide as a fluid sludge.  Solubility of the hardness ions is based on pH and alkalinity.  Silica is also reduced through adsorption into the MgOH. 

2. Is there any other technolgoies to remove hardness ?
