Question

How does ion exchange soften water?

Answer 1

Ion exchange includes expelling the hardness particles calcium and magnesium and supplanting them with non-hardness particles, commonly sodium provided by broke down sodium chloride salt, or saline solution. The conditioner contains a microporous trade sap, for the most part sulfonated polystyrene dots that are supersaturated with sodium to cover the dot surfaces. As water goes through this gum bed, calcium and magnesium particles append to the tar dots and the approximately held sodium is discharged from the pitch into the water. x

Answer 2

How does ion exchange soften water?

Ion exchange units that replace calcium and magnesium ions from water

are khown as water softeners .they may also remove varying amount of

other inorganic pollutants such as metals ,but they will not remove

organic chemicals pathogens,particles ,or radon gas .water softener

units work most efficiently with particulate free water.

principles of Ion Exchange to soften water. Calcium and magnesium ions

are atoms having a positive electrical charge,as do sodium and

potassium ions.Ions of the same charge can be exchanged. in the

exchange process,a granular substance (usually a resin ) that is coated

with sodium or poassium ions comes into contact with water containing

calcium and magnesium ions.two positively charged sodium or

potassium ions are exchanged (released into water) for every calcium or

magnesium ion that is held by the resin   .

Ion Exchange unit components. A water softener can be as simple as a

tank to hold the exchange resin together with appropriate piping for raw

(inlet) and treated (outlet) water .modern water softeners include a

separate tank for the brine solution   used to regenerate the resin ,additional valves to back wash the resin and switches for automatic operation
