5T Ultrapure Water Plant With Secondary RO, EDI & Polished
Mixed-Bed Polisher
I.Product Description
This ultrapure water system is designed for high-end applications
such as pharmaceutical production, laboratories, microelectronics,
and power plants.
It adopts secondary reverse osmosis (RO), electrodeionization
(EDI), and a polished mixed-bed polisher to ensure stable water
quality with resistivity up to 18.2 MΩ·cm.
The plant features PLC automatic control, intelligent monitoring,
and 316L stainless steel piping, ensuring long-term reliable
operation.

FAQ
1. Q: Which machine should I choose?
A: It depends on your raw water quality and your requirements for
permeate water.
Usually, there are three parts: pretreatment, the RO machine, and
post-treatment. Pretreatment could be a UF(ultra filtration)
system,anti-scale dosing system, flocculant dosing system,
disinfectant dosing system, water softener, sand filter, carbon
filter, security filter, etc. Post treatment could be UV
sterilizer, Ozonizer, ClO2 sterilizer, etc. And maybe you need an
EDI system. We will choose the proper process according to your raw
water quality and permeate water.
2. Q: What’s your machine material?
A: For pretreatment tanks, we usually use FRP or S.S. The RO frame
could be S.S., carbon steel. For pipes, it is usually SS and UPVC.
We can choose the material according to your special requirements.
3. Q: What’s the control method?
A: For pretreatment, you can choose manual or automatic; for the
whole system, we use relay, PLC, or man-machine interface remote
control
4. Q: Which spare parts need to be changed regularly?
A: Filter cartridge in the security filter and RO membranes. For
the filter cartridge, it needs to be changed every 3-6 months, and
for the RO membrane, you need to change it every 1-3 years. It
depends on your water quality and how you maintain the machine.
5. Q: What’s your warranty?
A: Our warranty is 1 year. But to our experience, our machine can
work for 5 years before repair.
6. Q: What’s your electricity requirement?
A: Our machine could be 380V/220V/110V, 50HZ/60HZ, 3 phase/single
phase. We can do customer-made products.
7. Q: What’s your machine size?
A: It depends on the capacity requirement, and we can make changes
according to your space.
8. Q: What’s your membrane brand?
A: We have all kinds of brands, as guests request.
9. Q: What’s the purchase procedure?
A: Customer sends Inquiry -----we provide solution and
quotation-----customer confirms and places order-----we send
PI-----customer makes first payment----we arrange
production----customer makes the rest payment-----we ship goods
from our factory.
