What is the lime alkalization method for iron removal? How to prepare lime solution?

Lime alkalization method for iron removal: After being digested, lime is converted into lime slurry which is then added to the raw water. Under high pH conditions, it reacts with bicarbonates to form calcium carbonate and magnesium hydroxide precipitates. Aeration is carried out to remove iron and manganese, as well as to reduce the total hardness and total dissolved solids in the water. Quicklime is reacted with a certain amount of water to prepare a lime solution.
