EDI First-level Reverse Osmosis Polishing Resin Equipment

Product Description

Product Description


Ultra-pure water: It not only removes the conductive medium in the water almost completely, but also removes the non-dissociated colloidal substances, gases and organic matter in the water to a very low level. The resistivity is greater than 18MΩ*cm, or close to the limit value of 18.3MΩ*cm. Ultra-pure water is a level that is difficult to achieve in general processes. It adopts four major steps: pretreatment, reverse osmosis technology, ultra-purification treatment and post-treatment, multi-stage filtration, high-performance ion exchange unit, ultra-filtration filter, ultraviolet Lamp, Except for various treatment methods such as TOC device, the resistivity can reach 18.25MΩ*cm. Ultra-pure water is water produced by the US scientific and technological community in order to develop ultra-pure materials (semiconductor original materials, nano-fine ceramic materials, etc.) using distillation, deionization, reverse osmosis technology or Other appropriate supercritical fine technology. This kind of water is in addition to Except for water molecules (H20), there are almost no impurities, no bacteria, viruses, chlorinated dioxins and other organic matter. Of course, there are no minerals and trace elements required by the human body. Generally, it cannot be consumed directly. It is harmful to the body and will be precipitated out of the human body. There are a lot of ions in it.
Advantages of EDI device:
The EDI device is applied after the reverse osmosis system to replace the traditional mixed ion exchange technology (MB-DI) to produce stable deionized water. Compared with mixed ion exchange technology, EDI technology has the following advantages:
①Stable water quality; ②Easy to realize automatic control; ③No shutdown due to regeneration; ④No chemical regeneration required; ⑤Low operating cost; ⑥Small floor space; ⑦No sewage discharge.
EDI technology is a revolutionary water treatment technology, a continuous desalination process that organically combines electrodialysis and ion exchange, and is a high-tech green environmental protection technology. EDI water purification equipment has the advantages of continuous water output, no need for acid and alkali regeneration, and unattended. It has gradually replaced the mixed bed as a finishing equipment in the system for preparing pure water.
The EDI device is applied after the reverse osmosis system to replace the Ion Exchange Resin and does not require acid and alkali regeneration. It has the characteristics of stable water quality, low operating costs, convenient operation and management, and small footprint.
Application fields of EDI ultrapure water equipment:
1. Electronics, electricity, electroplating, lighting appliances, laboratories, food, paper, daily chemicals, building materials, paint, batteries, laboratory, biology, pharmacy, petroleum, chemical, Steel, glass and other fields.
2. Purified water for chemical process water, chemical agents, cosmetics, etc.
3. Single crystal silicon, semiconductor wafer cutting and manufacturing, semiconductor chips, semiconductor packaging, lead cabinets, integrated circuits, liquid crystal displays, conductive glass, picture tubes, circuit boards, optical communications, computer components, capacitor clean products and various components, etc. Pure water is used in the production process.
