Demineralization is often a term used interchangeably with deionization. Demineralization is essentially removing all the minerals that can be found in water. This process is usually done when the water is to be used for chemicals processes and the minerals present may interfere with the other chemicals. For eg. all chemistic and beauty products have to be made with demineralized water for this reason. With the demineralization process, the water is "softened" replacing the undesired minerals with different salts (NaCl). Demineralized water has a higher conductivity than deionized water.
When the process requires water to be of higher purity then 2 bed D M Plant system mixed is included. Mixed bed comprises of both Cation and anion. This mixed bed is used essentially as a extension.
Mixed bed deionization is a mixture of cation and anion resin combined in a single ion exchange column. With proper pretreatment, product water purified from a single pass through a mixed bed ion exchange column is the purest that can be made. Most commonly, mixed bed demineralizers are used for final water polishing to clean the last few ions within water prior to use.
Small mixed bed deionization units have no regeneration capability. Commercial mixed bed deionization units have elaborate internal water and regenerant distribution systems for regeneration. A control system operates pumps and valves for the regenerants of spent anions and cations resins within the ion exchange column. Each is regenerated separately, then remixed during the regeneration process. Because of the high quality of product water achieved, and because of the expense and difficulty of regeneration, mixed bed demineralizers are used only when the highest purity water is required.
Processes like Sand Filter /Ultrafiltration / Reverse Osmosis are the pressure driven process, whereas electrically driven approach encompasses electro-dialysis & electro di ionization. This Electro di Ionization process is generally applied when aim is to remove the ions (Cation & Anion) from water, & this is been achieved through the selective control & transport of ion species.
The fundamental principal behind electrically driven process is the passage of ions through a selective barrier (Ion Exchange Membrane) due to driving force (Electric field). Ion Exchange membranes play a critical role in this process & they are responsible for accepting & rejecting ions in the establishment of dilute & concentrate compartments. Electro di ionization is the process that based on selective migration of ions in solutions through the ion exchange membranes under activation of electric field.
This is a continuous process (Generation of process water as well as online regeneration) hence the same is also called as CEDI Technology (Continuous De Electro Ionization) CEDI is the most popular technology for electrically driven process in industries (Pharma Sector / Power Sector) as it separates the undesired ions from aqueous solutions at low operational cost & with the advantage that it does not generates the residues.
