The ion exchange process is carried out by employing two types of ion exchange materials cation exchangers and anion exchangers fig.
Water treatment ion exchange process diagram.
Ion exchanger in water treatment process.
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.
Treatment of process condensate in various industries production of ultra pure water for the semiconductors industry.
These systems work by exchanging specific ions for other ions.
Removal of ions minerals from ha.
Ion exchange is a water treatment method where one or more undesirable ionic contaminants are removed from water by exchange with another non objectionable or less objectionable ionic substance.
Rohm and haas ion exchange ion exchange introduction 1 fd sep 2008 ion exchange for dummies an introduction water water is a liquid.
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.
As hard water passes through a softener the calcium and magnesium trade places with sodium ions figure 1.
Water softening water purification method.
Typically the contaminants in the condensate system are particulate iron and copper.
Waste water for advanced treatment.
All natural waters contain some foreign substances usually in small amounts.
Ion exchange in water softening water softening is not a wastewater process.
In the ion exchange process sodium ions are used to coat an exchange medium in the softener.
The exchange occurs between the ions of insoluble exchange material ion exchange materials and the ions of different species in solution i e.
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.
Water is made of water molecules formula h2o.
This video explains the demineralisation process in detail.
Both the contaminant and the exchanged substance must be dissolved and have the same type of electrical charge positive or negative.
The exchange medium can be natural zeolites or synthetic resin beads that resemble wet sand.
