Water softening water purification method.

Ion exchange process in water treatment ppt.

As hard water passes through a softener the calcium and magnesium trade places with sodium ions figure 1. 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. 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. In the ion exchange process sodium ions are used to coat an exchange medium in the softener.

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 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. From it and equivalent amount of h ions are released from this column to water. M prasad naidu msc medical biochemistry ph d research scholar.

The exchange medium can be natural zeolites or synthetic resin beads that resemble wet sand. There is a reversible exchange or similar charged ions mostly similar charged ions like cations or anions can be separated. 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. Water ionization treatment apparatus working on the principal of static electricity which is produced by the friction of water h2o with the carbon.

Ion exchange describes a specific chemical process in which unwanted dissolved ions are exchanged for other ions with a similar charge. Steam for turbines and process steam for industrial applications etc. Process of ion exchange to soften water. 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.

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. The best water purifier water pollution is a serious threat in pakistan as almost 70 of its surface as well as ground water reservoirs have highly been contaminated by various organic inorganic substances. Ion exchange process is established when the. This video explains the demineralisation process in detail.

Ion exchange ix systems are used across a variety of industries for water softening purification and separation purposes. Possible areas of use.
