CanpureAbbreviationEDIAlso known as continuous electrodialysis desalination technology, it scientifically integrates electrodialysis technology and ion exchange technology. Through the selective permeation of anions and cations and the exchange effect of ion exchange resins on ions in water, it realizes the directional migration of ions in water under the action of an electric field, thereby achieving deep purification and desalination of water. And the filled resin is continuously regenerated through the hydrogen ions and hydroxide ions produced by water electrolysis, thusEDIThe water production process can continuously produce high-quality ultrapure water without acid or alkali chemical regeneration. It has the advantages of advanced technology, compact structure and simple operation, and can be widely applied in the fields of power, electronics, medicine, chemical engineering and laboratories. It is a green revolution in water treatment technology.

　　Kanpur Equipment provides innovative membrane products and membrane technologies to the global water treatment market. Kanpur membrane products and membrane technologies have obtained multiple patented and proprietary technologies, As a result, extraordinary performance and achievements were achieved.EDIThe device is applied after the reverse osmosis system, replacing the traditional mixed ion exchange technology(MB-DI)Produce stable deionized water.

　　Next, let's introduce the Cample in water treatment equipmentEDIEquipment

　　In the tap water we use daily, there are large amounts of dissolved salts such as sodium, magnesium, calcium, chlorine, silicon and nitrates. These salts are composed of positively charged ions(Positive ion)And negatively charged ions(Negative ion)Composition.EDIThe desalination rate of the facilities can be as high as99%The above, if anyEDIBefore the facility, reverse osmosis equipment is used to conduct preliminary desalination treatment on the water, and then it passes throughEDIModule desalination can produce products with a resistivity as high as15M Ω.cmThe above ultrapure water.

　　CampbellEDIEquipmentFeatures: Small floor space;The effluent quality is high and the water output can be adjusted;No acid or alkali consumption, automatic regeneration;Water production resistance≥15MΩ.cm(25℃);It is applicable to industries such as boiler feed water, chemical engineering, electronics, automotive industry, power plant water treatment, metallurgy, electroplating and electrophoresis, etc.

　　EDIAdvantages of the equipment

　　1, Continuously produce ultrapure water, with excellent stability of the effluent quality, and generate ultrapure water at a high rate(The yield can be as high as95%);

　　2, Modular production enables fully automatic control of equipment

　　3, No acid or alkali regeneration is required, and the machine will not shut down due to regeneration

　　4, No acid or alkali dilution transportation facilities or acid and alkali reserves are required

　　5, The equipment has a compact structure, small volume and occupies little space

　　6, Reliable in use, avoid manual contact with acids and alkalis

　　7, It saves backwashing and cleaning water, generates no regenerative wastewater, and does not require sewage treatment equipment

　　8, It is easy and convenient to install, and the installation cost is low;Reduce the operating and maintenance costs of the equipment

　　9, The equipment is easy to operate and has a relatively low labor intensity

　　When the supplied raw water entersEDISystemAfter that, it is divided into two parts, with the majority flowing into the resin/Inside the membrane, while the other part flows along the outer side of the membrane plate to wash away the ions that have escaped from the membrane. The dissolved ions in water retained by the resin, under the action of the electrode, the cations move towards the negative electrode and the anions move towards the positive electrode. The anions pass through the anion membrane and are discharged from the resin/Outside the membrane. Concentrated ions are discharged from the wastewater flow path. Deionized water from the resin/Outflow from the membrane.

　　If one wants to maintainEDIThe basic requirement for a device to be in an optimal working condition and reduce malfunctions is to be correctEDIThe water inflow to the device should be strictly controlled and appropriate pretreatment should be carried out. Impurities in the influentEDIThe device has a significant impact. Excessive impurities may lead to a reduced service life of the equipment.
