Deion water purifier - Ultra clean water filtration technology

Deion water purifiers are used in fields such as laboratories, experiments, and general clinics such as washing surgical instruments, steaming and drying examination instruments.

What is deion water?

Deion water, also known as ultra-pure water, is water produced by distillation and ion exchange. After being filtered through the deion water filter system, the water will not contain any impurities.

Depending on the filtration method of each type of filter, and depending on each usage need, deion water is divided into 3 different types:

The water is super clean, not contaminated with any dissolved impurities, ionic substances, or organic substances. This deion water is the water with the most stringent requirements
Water is distilled several times or reverse osmosis then distilled. Water is still contaminated with a very small number of ions, inorganic or organic
Single distilled, deionized water is used in laboratories for routine experiments.

Operating principles, advantages and disadvantages of Deion water purifiers

Currently, E&C Vietnam Environmental Technology Services Joint Stock Company is retailing and distributing two lines of deion water production machines: deion water purifiers using ion exchange materials and deion water purifiers using the deion method. Electrical deionization

The operating principle of the deion water purifier uses ion exchange materials
Structure of the machine

Deion water purifier uses ion exchange filter material including the following main components:

Coarse filter columns: Such as sand, gravel, manganese particles, and activated carbon filter columns are responsible for removing large impurities and heavy metals.
High pressure pump: Provides water from the source to the deion purifier
Force sensor and purifier control system operate
RO membrane: Removes small sized impurities, inorganic and organic impurities
Deion filter core system: The filter core contains ion exchange particles, which are responsible for removing all microscopic ion particles, obtaining deion water.
Operational process

Water is supplied from the source into the machine's water filtration system. After passing through the coarse filter columns and RO membranes, the water is almost completely removed from impurities, dirt, bacteria, etc. The water obtained after filtering is pure water, but a few microscopic ions remain. . At this time, the remaining ions are processed after passing through the filter system containing ion exchange particles. The water obtained is finally called deion water

Advantages and disadvantages

Water filtration speed is fast, the amount of water collected is large, suitable for industrial models
Reasonable price
Small amount of wastewater
Easy to maintain and replace filter material
Easy to transport, easy to install
The disadvantage of deion water purifiers using ion exchange materials is the short filter replacement time

The operating principle of the deion water purifier is by deionization using electricity

Structure of the machine

Similar to the deion water purifier made of deionized materials, the structure of the electric deion purifier also has the following components:

Coarse filter columns include sand filter columns, gravel filter columns, activated carbon filter columns... used to remove heavy metals and large impurities.
High pressure pump: Transports water from the source to the filter
Filter control system
Force sensors
RO filtration system: RO filter membrane removes small sized impurities
The deionization system uses electricity
Operational process

The high pressure pump will operate, supplying water from the source to the deion purifier. Water will pass through the filter cores of the crude filter column. Impurities, dirt, and heavy metals are retained. Water continues to be pumped through the RO filtration system. Here, remaining inorganic and organic impurities in the water will be filtered out. The resulting water is fed into an electrical deionization system. Based on the activities of the electrodes, all ions will be completely removed, yielding deion water for use.

Advantages and disadvantages of electrical deionization method

Fast water filtration speed
Small amount of wastewater
Easy to replace filter materials in the machine
Easy to transport and install
However, the machine has the disadvantage of being more expensive than water purifiers using ion exchange materials
Application

Being ultra-clean water, deionized water is widely used in laboratories requiring high water quality
Used in pharmaceutical and medical industries. Prepare antiseptic salt solution, physiological saline, use to clean medical equipment, wash surgical instruments, steam and dry examination instruments.
Used in the electronic components manufacturing industry
