Description

Technical Field

[0001] The present invention relates to the technical field of ultrapure water, in particular to an electrodeionization mechanism for preparing ultrapure water. Background Art

[0002] The patent with application number 202211375228.X discloses a method for ultrapure water electro-deionization (EDI), which includes the following steps: S1: pressurizing raw water to provide pressure to the raw water and send the raw water to subsequent equipment; S2: multi-media filtration to remove suspended impurities in the water to make the water clear; S3: activated carbon filtration to remove discoloration and odor, remove pigments, colloids, odor and heavy metal ions in the water, etc., and reduce the chemical oxygen demand of the water; S4: pure water softening to reduce water hardness and reduce the concentration of calcium and magnesium ions in the water; S5: precision filtration to further remove microorganisms and suspended matter in the water; S6: reverse osmosis filtration, a booster pump provides pressure to send water to the reverse osmosis equipment, and uses a reverse osmosis membrane to remove more than 95% of soluble solids and almost all bacteria in the water, thereby improving the purity of the water. The present invention can greatly reduce the produced calcium and magnesium ions, residual ions and bacteria by adding a filtration device before and after the EDI module, thereby increasing the purity of ultrapure water and facilitating use.
