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