Ion Exchange Method For Water Treatment Ppt

Treatment but chemical mechanism is ion exchange rather than adsorption.

Ion exchange method for water treatment ppt.

Water softeners usually use sodium na as the exchange ion. These have very low exchange capacity ion exchange efficiency. Ions in the water are exchanged for other ions fixed to the beads. Dvorak extension environmental engineering specialist the presence of calcium ca and or magnesium.

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. 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. An ion exchange water softener exchanges the hardness minerals calcium and magnesium dissolved in water for sodium.

Pellicular type with ion exchange film. The particles have a size of 30 40µ with 1 2µ film thickness. The two most common ion exchange methods are. Structural types of ion exchange resins 1.

The ion exchange process percolates water through spherical porous bead resin materials ion exchange resins. 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. Ion exchange resins are insoluble granular substances which have in their molecular structure acidic or basic radicals that can be exchanged. Water softening ion exchange sharon o.

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. An ion exchanger is an insoluble substance containing loosely held ions which can be exchanged with other ions in solution which come in material. 10 ion exchange process 1.

Ion exchange is a water treatment commonly used for water softening or deminerialization and to remove other substances from water. The positive or negative ions fixed on these radicals are replaced by ions of the same sign in solution in the liquid in contact with them.
