Ion Exchange Method For Water Treatment Ppt

The ion exchange process percolates water through spherical porous bead resin materials ion exchange resins.

Ion exchange method for water treatment ppt.

Skipton extension water quality educator bruce i. Sodium ions are supplied from dissolved sodium chloride salt also called brine. This soft mineral is contained on the softener resin beads and does not build up on surfaces as scale. Ions in the water are exchanged for other ions fixed to the beads.

0 01 0 1 meq g. 10 ion exchange process 1. The two most common ion exchange methods are. Ion exchange process 2.

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. The particles have a size of 30 40µ with 1 2µ film thickness. 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.

Pellicular type with ion exchange film. Ion exchange resins are insoluble granular substances which have in their molecular structure acidic or basic radicals that can be exchanged. Structural types of ion exchange resins 1. Water softening ion exchange sharon o.

An ion exchanger is an insoluble substance containing loosely held ions which can be exchanged with other ions in solution which come in material. Ion exchange is a water treatment commonly used for water softening or deminerialization and to remove other substances from water. Treatment but chemical mechanism is ion exchange rather than adsorption. An ion exchange water softener exchanges the hardness minerals calcium and magnesium dissolved in water for sodium.

These have very low exchange capacity ion exchange efficiency. Ions electrically charged atoms or molecules cations and anions can have one or more charges mostly 1 to 3 and can be made of one or.
