For Option 1, a slaker system is required to convert ,quicklime, (CaO) to slaked or hydrated lime (Ca(OH)2). This is done by mixing water with the ,quicklime, and allowing the following exothermic reaction to take place: CaO + H2O --> Ca(OH) 2 The slaked lime can then be made up to a milk-of-lime solution ,by adding, additional make-up water.

Phosphorus is removed from wastewater by adding lime (CaO) or Ca(OH) 2). The lime first react with alkaline bicarbonate in the wastewater to form calcium carbonate (CaCO 3). Increase in the pH causes excess ions in the wastewater to react with phosphate to form hydroxylapatite [Ca 5 (OH)(PO 4) 3] which is precipitated out as shown in Equation (3) 5.
