Water Treatment Ion Exchange Process Diagram

Water is made of water molecules formula h2o.

Water treatment ion exchange process diagram.

All natural waters contain some foreign substances usually in small amounts. 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. 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 in water softening water softening is not a wastewater process.

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. The exchange medium can be natural zeolites or synthetic resin beads that resemble wet sand. This video explains the demineralisation process in detail. Treatment of process condensate in various industries production of ultra pure water for the semiconductors industry.

Rohm and haas ion exchange ion exchange introduction 1 fd sep 2008 ion exchange for dummies an introduction water water is a liquid. Both the contaminant and the exchanged substance must be dissolved and have the same type of electrical charge positive or negative. Ion exchange uses are not limited to process and boiler water makeup. Ion exchange can be used to purify or polish returned condensate removing corrosion products that could cause harmful deposits in boilers.

Typically the contaminants in the condensate system are particulate iron and copper. 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 softening water purification method. The exchange occurs between the ions of insoluble exchange material ion exchange materials and the ions of different species in solution i e.

Removal of ions minerals from ha. Waste water for advanced treatment. These systems work by exchanging specific ions for other ions. As hard water passes through a softener the calcium and magnesium trade places with sodium ions figure 1.

The ion exchange process is carried out by employing two types of ion exchange materials cation exchangers and anion exchangers fig.
