Principle:

Ultra-pure water equipment is the use of pretreatment, reverse osmosis technology, ultra-purification treatment and post-treatment methods, the conductive medium in the water is almost completely removed, and the water does not dissociate colloidal substances, gases and organic matter are removed to a very low degree of water treatment equipment.

• Composition of equipment：

• 
  

• Ultra-pure water system equipment is usually composed of a pre-treatment part, a reverse osmosis host part, and a post-treatment part.

1, Pre-treatment by quartz sand filter, activated carbon filter, automatic water softener, precision filter composition, can also choose ultrafiltration system as a pre-treatment, the main purpose of pre-treatment is to remove the sediment contained in raw water, rust, colloidal substances, suspended matter, chrominance, odor, biochemical organic matter.

2, the reverse osmosis main machine is mainly composed of high pressure pump, membrane shell, reverse osmosis membrane component, online instrument, control electrical and so on. As long as the number of membranes and the type of pump is properly selected, the desalination rate and water production of the reverse osmosis host can reach the rated index, and the effluent conductivity can be guaranteed to be less than or equal to 10us.CM.

3, the post-treatment part is to further deepen the treatment of pure water made by reverse osmosis to make ultra-pure water, usually ion exchange mixed bed equipment or EDI equipment, according to customer requirements, the water resistance can reach 18.25 mΩ.cm.

EDI membrane stack working principle：

Ion exchange is a special solid adsorption process that is carried out by an electrolyte solution of an ion exchanger. The general ion exchanger is a solid granular substance that is insoluble in water, that is, ion exchange resin. It can absorb a cation or anion from the electrolyte solution, and the other ions contained in itself with the same charge symbol are exchanged in equal amounts and released into the solution, which is the so-called ion exchange. According to the type of ions exchanged, ion exchangers can be divided into two categories: cation exchangers and anion exchangers.

EDI high purity water equipment, as a device for making ultra-pure water, can produce up to 10-18.2 megohm. Therefore, it is widely used in microelectronics industry, semiconductor industry, power generation industry, pharmaceutical industry and laboratory. It can also be used as pharmaceutical distilled water, water for food and beverage production, make-up water for boilers in power plants, and high purity water for other applications.

EDI systems have been accepted by almost all companies and end users who require high purity water. EDI has proven to be a cost-effective solution for end users and water treatment companies. EDI systems also replace mixed beds in the field of refining, and together with RO, EDI systems will provide a continuously operating, chemical-free system.

Performance Advantage :

1, can continuously and stably produce high-quality pure water, without stopping due to resin regeneration;

2, no pollutant discharge, not only environmental protection and save the investment in waste liquid treatment;

3, the equipment structure is compact, occupies a small area, saves space, but also has the advantages of energy saving;

4, factory completion of device debugging, small workload, easy training;

5, daily maintenance, simple operation, low labor intensity.
