EDI Water Plant For Electronics Industry, Low Operating Cost
EDI, also known as continuous electric desalination technology, is a
green revolution in water treatment technology. This new technology
can replace the traditional ion exchange device to produce
ultrapure water with a resistivity of 16-18MΩ · CM
EDI Features
1) Continuous operation, stable effluent quality
2) Easy to realize automatic control
3) No need for acid and alkali regeneration
4) No downtime due to regeneration
5) Saved water and reclaimed sewage treatment facilities
6) High water production rate (up to 95%)
7) Small footprint
8) Reduce operation and maintenance costs
9) Simple installation, low operating cost,
EDI(Electrodeionization) technology scientifically combine electrodialysis with ion exchang technology and substitutes the traditional ion exchang bed technique.
| specification | notes | working range | optimum performance |
| feedwater source | RO water , direct feed , or with intermediate break tank plus
filter | | |
| EDI feed conductivity | ionic load determines size of the working bed and polishing bed
within the EDI | 1-20us/cm | 1-6us/cm |
| feed conductivity equivalent | | less than 50us/cm | less than 10us/cm |
| PH | low ph feedwater typically indicators the presence of CO2 which
will decrease quality | 5.0-9.5 | 7.0-7.5 |
| total CO2 |  | less than 5mg/l | less than 2mg/l |
| temperature | | 5℃to 40℃ | 20℃to30℃ |
| hardness |  | less than 1.0ppm at 90% recovery | |
| organics | TOC | less than 0.5ppm | not detectable |
| metals | Fe,Mn,transition metals | less than 10ppb | not detectable |
| silica , SiO2 | typically dissolved , reactive | less than 0.5ppm | less than 0.2ppm |
| oxidizers | Cl2 and O3 typically | not detectable | not detectable |
| particles | recommended direct feed particle - free RO permeate , or 1μm pre -
filtration of feed from intermediate tank | SDI less than 1 | SDI less than 0.5 |
What you can do
Tell us what`s your raw water as input water for our ro water
treatment system first.If possible , it`s better you can give us a
water analysis report ,so or engineer can design a suitable system
to u.
Then tell us what`s the water production flow rate you need per
hour ?
Tell us what`s the application of pure water from ro water
treatment system,for drinking
,industrial,hospital,Pharmaceutical,chemical experiments,lab test
or others ?
Lastly,pls tell us your requirements for the pure water quality
,material of pipes and filters housing,and the brands of meters and
fittings.
We look forward to cooperating with you.
