EDI Water Treatment Plant Working Principle
In the EDI membrane block, a certain number of EDI units are
separated by grids to form a concentrated water chamber and a fresh
water chamber. In turn, negative/positive electrodes are provided
at both ends of the cell. Driven by direct current, the anions and
cations in the water flow through the fresh water chamber migrate
to the concentrated water chamber through the anion and cation
exchange membrane respectively and are removed in the fresh water
chamber.

The Main Reasons for EDI Water Treatment Plant
1. The EDI membrane block runs at high current for a long time, and
the accumulated heat cannot be dissipated, causing the EDI to be
close to the two poles.
The diaphragm is heated and deformed, the pressure difference of
the EDI concentrated water increases, and the water quality and
water volume decrease to varying degrees.
2. If the EDI membrane block is not cleaned and maintained for a
long time, it will cause calcium and magnesium scale on the EDI
membrane and channel, which will make the
The water pressure difference increases, resulting in a decrease in
the quality of the produced water and an increase in the voltage,
which in turn makes the current unable to be adjusted.
ultimately unusable.
3. The use of unreasonable cleaning and disinfection agents will
directly lead to damage and fragmentation of EDI resin, and water
in and out.
The pressure difference increases, resulting in a decrease in the
quality and quantity of the produced water. 4. The EDI system is
powered on under water shortage
It directly leads to the heating and burning of the diaphragm and
resin, and the cleaning is invalid and cannot be used.
5. There is no security filter before the EDI enters the water,
which directly causes foreign matter to block the EDI channel, and
the pressure difference between the inlet and outlet increases.
Caused a serious decline in the amount of water produced, cleaning
is ineffective.
6. Poor pretreatment (softener, sodium bisulfite, RO, etc.),
control system failure/failure (safety
full interlocks, low flow protection issues), improper system
design.
7. The residual chlorine in the EDI water exceeds the standard,
resulting in the oxidation of the resin of the EDI membrane block
and the oxidation of the diaphragm. Increased differential
pressure, flux decline, water quality declines.

Daily Maintenance of EDI Water Treatment Plant
1. The personnel who operate the industrial EDI ultrapure water
treatment equipment must switch the equipment on and off strictly
according to the operation process, and the operator needs to
inspect the equipment at least three times a day to ensure the
normal operation of the ultrapure water equipment. .
2. The operator should do more than 2 patrol inspections every day
to ensure the normal operation of the equipment.
3. Operators and maintenance personnel should always pay attention
to keeping the equipment clean and tidy, eliminate dripping and
leakage problems in time, and make records for problems that cannot
be solved in time, and must be solved after research.
4. All joints and water pipes of industrial EDI ultra-pure water
treatment equipment should be checked regularly, such as whether
there is looseness or damage, etc., and the operation of
high-pressure pumps and water pumps should also be checked
regularly. Pay attention to Freeze-proof.
5. Regularly replace the filter screen and PP cotton of the
industrial EDI ultra-pure water treatment equipment to ensure that
the water treatment standard is within the range.
6. Regularly check the operation of the water pump and
high-pressure pump, and report any problems in time.
7. If the operator finds that the equipment is abnormal, he should
immediately find out the reason and report it in time.
8. Always check whether the connector of the electric control box
is off or disconnected, and ensure the safety of electricity use.
