Ion exchange method for water treatment ppt.
Ion exchange is a water treatment process commonly used for water softening or demineralization but it also is used to remove other substances from the water in processes such as dealkalization deionization and disinfection.
Water softeners usually use sodium na as the exchange ion.

Pellicular type with ion exchange film.
Sodium ions are supplied from dissolved sodium chloride salt also called brine.
Ions in the water are exchanged for other ions fixed to the beads.
In the ion exchange process sodium ions are used to coat an exchange medium in.
The two most common ion exchange methods are.
In the ion exchange process a granular substance usually a resin that is coated with sodium or potassium ions comes into contact with water containing calcium and two positively charged sodium or potassium ions are exchanged released into the water for every calcium or magnesium ion that is held by the resin.
An ion exchanger is an insoluble substance containing loosely held ions which can be exchanged with other ions in solution which come in material.
Treatment but chemical mechanism is ion exchange rather than adsorption.
The ion exchange process percolates water through spherical porous bead resin materials ion exchange resins.
