Product Description of EDI water purification plant
EDI is a cost effective, environmentally friendly alternative to conventional post-RO ion ex-changer applications in high purity water treatment.
Electro-deionisation (EDI) is a continuous deionization process combining electrodialysis (ED) and ion-exchange(IE) membranes and resins for producing ultra pure water.
There are also EDI units that are often referred to as continuous electrodeionization (CEDI) since the electric current regenerates the resin mass continuously. CEDI technique can achieve very high purity, with conductivity below 0.1 μS/cm.

Working Flow of EDI water purification plant
1. Raw water pump-- provide the pressure to quartz sand filter/active carbon filter.
2. Multi-medium filter-- get rid of turbidity, suspended matter, organic matter, colloid, ect
3. Actived carbon filter--Remove the color, free chloride, organic matter, harmful matter, ect.
4. Water softener--exchange "ions" of calcium and magnesium with the most common and easiest method.
5. Security filter--prevent large particles, bacteria, viruses into RO membrane, accuracy is 5um.
6. High pressure pump-- Provide the high pressure to RO membrane.
7. 2 stages RO membrane-- remove more than 99% ions, bacteria, salt, microorganism, heavy ions, colloid,emdotoxin and other particles in the water.
8. EDI module-- produce more than 15MΩ.cm ultrapure water.
Theory of EDI water purification plant
An electrode in an electrochemical cell is referred to as either an anode or a cathode, terms that were coined by Michael Faraday. The anode is defined as the electrode at which electrons leave the cell and oxidation occurs, and the cathode as the electrode at which electrons enter the cell and reduction occurs. Each electrode may become either the anode or the cathode depending on the voltage applied to the cell. A bipolar electrode is an electrode that functions as the anode of one cell and the cathode of another cell.
Each cell consists of an electrode and an electrolyte with ions that undergo either oxidation or reduction. An electrolyte is a substance containing free ions that behaves as an electrically conductive medium. Because they generally consist of ions in solution, electrolytes are also known as ionic solutions, but molten electrolytes and solid electrolytes are also possible. They are sometimes referred to in abbreviated jargon as lytes.
Water is passed between an anode (positive electrode) and a cathode (negative electrode). Ion-selective membranes allow the positive ions to separate from the water toward the negative electrode and the negative ions toward the positive electrode. High purity deionized water results.
