High-Pressure Water Purification Equipment With Multi-Stage Filtration For Water Purity

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.
