Water Treatment Ion Exchange Process Diagram

As hard water passes through a softener the calcium and magnesium trade places with sodium ions figure 1.

Water treatment ion exchange process diagram.

Treatment of process condensate in various industries production of ultra pure water for the semiconductors industry. The exchange medium can be natural zeolites or synthetic resin beads that resemble wet sand. Removal of ions minerals from ha. Ion exchange can be used to purify or polish returned condensate removing corrosion products that could cause harmful deposits in boilers.

In the ion exchange process sodium ions are used to coat an exchange medium in the softener. Today we discussed about an very important equipment which is used into the d m plant into a power unit that s equipment is ion exchanger which is used for treating the boiler water ion exchange or water conditioners one of the simplest methods now these days for removing hardness from a water supply is by use of a sodium zeolite water softener. Rohm and haas ion exchange ion exchange introduction 1 fd sep 2008 ion exchange for dummies an introduction water water is a liquid. Ion exchanger in water treatment process.

Both the contaminant and the exchanged substance must be dissolved and have the same type of electrical charge positive or negative. Waste water for advanced treatment. The exchange occurs between the ions of insoluble exchange material ion exchange materials and the ions of different species in solution i e. Water is made of water molecules formula h2o.

The ion exchange process is carried out by employing two types of ion exchange materials cation exchangers and anion exchangers fig. Typically the contaminants in the condensate system are particulate iron and copper. Ion exchange uses are not limited to process and boiler water makeup. Treatment of water pre demineralised with ion exchange resins polishing of reverse osmosis permeate polishing of sea water distillate treatment of turbine condensate in power stations.

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. These systems work by exchanging specific ions for other ions. Ion exchange in water softening water softening is not a wastewater process.
