Ion Exchange Process In Water Treatment Ppt

Introduction the process by which a mixture of similar charged ions can be separated by using an ion exchange resin ion exchange resin exchanges ions according to their relative affinities.

Ion exchange process in water treatment ppt.

Possible areas of use. Water softening water purification method. The exchange medium can be natural zeolites or synthetic resin beads that resemble wet sand. Removal of ions minerals from ha.

However it is worth mentioning it because it constitutes the largest application of ion exchange processes water softening consists of removing divalent ions such as ca or mg from water these ions result in the so called water hardness. This video explains the demineralisation process in detail. Ion exchange process is established when the. From it and equivalent amount of h ions are released from this column to water.

As hard water passes through a softener the calcium and magnesium trade places with sodium ions figure 1. There is a reversible exchange or similar charged ions mostly similar charged ions like cations or anions can be separated. Steam for turbines and process steam for industrial applications etc. But what exactly is it.

In the ion exchange process sodium ions are used to coat an exchange medium in the softener. M prasad naidu msc medical biochemistry ph d research scholar. 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. Ion exchange fundamentals the selection of an ion exchange process and the degree of demineralisation depend on the application in question and the additional operating and economical conditions.

Ion exchange ix systems are used across a variety of industries for water softening purification and separation purposes. Figure 1 process of ion exchange to soften water the hard water is passed first through cation exchange column which removes all the cations like ca 2 mg 2 etc. 2 ion exchange processes 2 1 foundations of ion exchange processes an ion exchange system consists of a solid phase insoluble the ion exchanger material surrounded by a liquid phase containing the solute of interest to be separated. Ion exchange describes a specific chemical process in which unwanted dissolved ions are exchanged for other ions with a similar charge.

Process of ion exchange to soften water. While the chemistry of individual ion exchange reactions varies from one application to the next ix is a treatment process where dissolved ions are replaced by other more desirable ions of a similar electrical charge.
