Answer:

Explanation:

Permanent hardness is hardness (mineral content) that cannot be removed by boiling. When this is the case, it is usually caused by the presence of calcium sulfate and/or magnesium sulfates in the water, which do not precipitate out as the temperature increases. Ions causing permanent hardness of water can be removed using a water softener, or ion exchange column.

Total Permanent Hardness = Calcium Hardness + Magnesium Hardness

The calcium and magnesium hardness is the concentration of calcium and magnesium ions expressed as equivalent of calcium carbonate.

Hardness can be removed thermal treatment.  It is due to the presence of Calcium, Magnesium, carbonate and bicarbonate ions.  Same way Permanent hardness is due to the presence of Calcium, Magnesium, Sulfate and Chloride ions.
