Product Description

EDI Ultra Pure Water Plant Ro Membrane EDI Water Treatment System

https://xajufu.en.made-in-china.com/company-Jufu-Water-Technology-Co-Ltd.html

EDI, also called electric desalination is a new ultra pure water technology which gradually developed in the 20th century, which combines electric dialysis technology and ions exchange technology. It is using the selectivity penerate function of anion and cation membrane and exchange function of ions exchange resin, under direct current electric field to make ion directed migration. Finally to make deep desalination of water. In the same time, hydrogen ion and hydroxide ion which produced when water ionized will regeneration, and it can produce ultra pure water continuously.

Process characteristics

EDI process using an ion selective membrane and ion exchange resin under dc voltage is sandwiched between two electrodes, between between the poles of dc electric field from the RO water processed by the removal of ions, EDI process system instead of the traditional hybrid resin bed to make deionized water, with ion exchange mixed bed big difference is that EDI can continuous to ion process, High degree of automation, and does not need acid and alkali regeneration.

Precautions for use and cleaning of EDI equipment

Matters needing attention when EDI device is running1. Must meet the water inlet conditions.2. Fresh water inlet pressure > concentrated water inlet pressure 10PSI≈0.07MPa.3. Product water outlet pressure ≥ Concentrate water discharge pressure 10PSI ≈ 0.07MPa.4. When the EDI rectification equipment is out of service, RO (or water of the same water quality) must not pass through the equipment.5. Reduce frequent downtime of equipment.

Equipment outage for a long time

1. If the EDI system is out of service for more than 3 days, it should be protected for a long time out of service to avoid the growth of microorganisms inside the EDI.2. Cut off all power switches in the PLC control cabinet.3. Allow the remaining water in the EDI piping system to drain to avoid stagnant water in between.4. Close all system valves.5. After restarting after a long period of shutdown, the membrane block may need to be disinfected, cleaned or regenerated.

Advantages of EDI compared with traditional mixed bed:

The advantages of continuous desalting by electrodialysis and deep desalting by ion exchange are retained;

Compared with ordinary ion exchange resin column, the amount of ion exchange resin is less, saving more than 95% of resin;

Ion exchange resin does not need acid and alkali chemical regeneration, saving a lot of acid and alkali and cleaning water, greatly reducing labor intensity;

No waste acid waste lye discharge, is clean production technology, green environmental protection products;

The process is easy to realize automatic control, EDI and reverse osmosis (RO), UF and other water treatment technology combined, can form a perfect high pure water production line;

Small footprint, and do not need to be like ion-exchange beds, a set of in-use, a set of regeneration of the repeated Settings.

Application of EDI Water Treatment Plant

Electronic chip high pure water;

Power high pressure boiler supply water;

Chemical, metallurgy, electroplating and other industries pure water, high pure water;

Biotechnology, pharmaceutical industry, medical devices, experimental technology ---- pure water, high pure water.
