High-Pressure Water Purification Equipment with Multi-Stage
Filtration for Water Purity
I.Overview
Multi-stage filtration high-pressure water purification equipment
is an advanced water treatment system that uses a high-pressure
pump to push water sequentially through multiple filtration stages,
achieving comprehensive water purification. Each stage targets
specific contaminants: pre-filters remove sediment, rust, and large
suspended particles; activated carbon or chemical filters adsorb
odors, residual chlorine, and certain organic compounds;
ultrafiltration or nanofiltration membranes eliminate
microorganisms, colloids, and some dissolved substances; and
reverse osmosis membranes further remove dissolved salts, heavy
metals, and other impurities, ensuring high-purity water.
Additional post-treatment options—such as ultraviolet
sterilization, mineralization, or pH adjustment—can be incorporated
as needed to further optimize water quality.

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 2 years. But in 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, most used are the Dow brand
membrane, or as requested by guests.
