The diluting water should be cold, because ,calcium hydroxide, is more soluble in cold water than in warm water. Quicklime is used in water softening plants and at large ,water treatment, plants because of its lower cost. Hydrated lime; Hydrated lime, also known as ,calcium hydroxide,, is a white powder formed when quicklime is slaked in water.

The best way to neutralize ,acid, in ,wastewater, is to dose with an alkali to maintain a neutral pH level. The traditional method to ,treat, acidic ,wastewater, involves the use of caustic soda, otherwise known as sodium ,hydroxide, (NaOH). Other widely used alkalis are soda ash (sodium carbonate) or hydrated lime (,calcium hydroxide,).
