In the ion exchange process sodium ions are used to coat an exchange medium in.

Ion exchange method for water treatment ppt.

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. Ion exchange resins are insoluble granular substances which have in their molecular structure acidic or basic radicals that can be exchanged. These have very low exchange capacity ion exchange efficiency.

The particles have a size of 30 40µ with 1 2µ film thickness. Ion exchange process 2. Water softening ion exchange sharon o. 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.

The two most common ion exchange methods are. 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. Skipton extension water quality educator bruce i. Ions in the water are exchanged for other ions fixed to the beads.

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. Water softeners usually use sodium na as the exchange ion. 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.

Structural types of ion exchange resins 1. An ion exchange water softener exchanges the hardness minerals calcium and magnesium dissolved in water for sodium. Sodium ions are supplied from dissolved sodium chloride salt also called brine. Ion exchange is a water treatment commonly used for water softening or deminerialization and to remove other substances from water.

10 ion exchange process 1. Dvorak extension environmental engineering specialist the presence of calcium ca and or magnesium.
