Industrial UF Ultrafiltration System – Fully Automatic with PLC Control

In recent years, surface water purification with ultrafiltration membrane has become an attractive alternative to conventional clarification. No or less need of chemical agents, good quality of produced water independent of feed water quality, good removal efficiency towards microorganisms, less production of sludge, compact process, and easy automation are some of the advantages of ultrafiltration compared to conventional treatment. Originally, ultrafiltration was used to remove turbidity and microorganism from good-quality surface water. Nowadays the main goal is to improve this technology and to apply it to worse quality sources for the removal of microorganisms, natural organic matter (NOM), Total Organic Carbon (TOC) including particulate organic carbon (POC) and dissolved organic carbon (DOC), disinfection by-products (DBPs) and other components.

Product Overview

Water and energy costs keep climbing. Environmental regulations get tighter. Corporate sustainability targets become more aggressive. For industrial water treatment operators, the pressure is on to do more with less—less water wasted, less energy consumed, less environmental impact.

Conventional UF systems typically operate at 1.4 to 3.5 bar and recover 85-95% of feed water. That's good, but not great. What if you could cut the operating pressure in half and push recovery above 98%? That's exactly what the DAGYEE High-Recovery Low-Energy UF System delivers.

This system is built for plant managers who are serious about sustainability—not as a marketing slogan, but as a measurable reduction in operating costs and environmental footprint. It combines high-flux PVDF membranes with intelligent process design to achieve performance that conventional UF systems simply can't match.

Less energy. Less water waste. Lower operating costs. That's the proposition.

Why a Containerized System?

There are plenty of reasons to put a water treatment plant inside a shipping container. Here are the ones that matter most:

Speed of Deployment
A conventional water treatment plant takes months to design, build, and commission. A containerized system takes days to ship and hours to commission. When water is urgently needed, that difference is everything.

Complete Mobility
The system is built to move. A flatbed truck delivers it. A crane sets it down. When the project ends, the same truck takes it to the next site. The equipment doesn't get left behind—it follows the work.

Minimal Civil Works
No foundations. No buildings. No permanent utilities. Just a reasonably level piece of ground, a water source, and a power connection. That's all it takes.

Plug-and-Play Simplicity
Everything is pre-installed and pre-wired inside the container. The operator doesn't need to be a water treatment specialist. The system is designed to be operated by someone with basic training. Connect the hoses, turn it on, and let it run.

Weather Protection
The container provides built-in shelter for all equipment. Rain, dust, wind, and extreme temperatures don't affect performance. The system operates reliably in conditions that would shut down an open-air plant.

Security
The container is lockable, providing physical security for equipment in remote or unstable locations. Vandalism and theft are real concerns in some settings—a shipping container offers practical protection.

Working Principle

The operating principle is standard UF, but the execution is optimized for efficiency.

Filtration Mode
Feed water enters the system through a strainer and pre-filter, then flows into the UF membrane array. The high-flux PVDF membranes operate at 0.5-1.5 bar. Clean permeate passes through and goes to the product tank. The small reject stream carries away concentrated contaminants.

Intelligent Backwash
Instead of backwashing on a fixed schedule, the PLC monitors TMP in real time. When TMP rises to a preset threshold, the system initiates a backwash. This typically happens less frequently than with timer-based systems—saving water, energy, and membrane wear.

Chemical Cleaning (As Needed)
When TMP can't be restored by backwashing alone, the system triggers a CEB cycle. Because the backwash schedule is optimized, chemical cleaning is also needed less often—sometimes half as frequently as conventional systems.

Post-Dilution (Optional)
The system can be configured to blend a small portion of reject water back into the feed stream to further improve overall recovery without compromising membrane performance.

Product Features & Advantages

Ultrafiltration offers numerous advantages in water treatment, making it an increasingly popular choice for municipal  and industrial applications. Hollow fiber UF membranes provide a physical barrier to suspended solids and pathogens to consistently produce a high-quality, low-turbidity, and low-SDI effluent.

Here are the key benefits of implementing an ultrafiltration system:

Pressurized or immersed membranes to suit the site requirements.
Greater output in the same footprint and helps reduce capital and lifecycle costs for the application.
Physical UF barrier provides consistent high-quality effluent exceeding stringent regulatory requirements through virtually any change in raw-water quality.
Low lifecycle cost optimized through extended membrane life and low energy and chemical use.
These benefits make ultrafiltration an attractive option for various water treatment applications, from municipal water supplies to industrial process water.

What Does Ultrafiltration Remove?

Ultrafiltration is highly effective at removing a wide range of contaminants from water. Here's a breakdown of what an ultrafiltration water filter can typically remove:

1. Particulate matter:
Suspended solids
Colloids
Turbidity
2. Microorganisms:
Bacteria (99.99% removal)
Protozoa (including Giardia and Cryptosporidium)
Many viruses
3. Organic compounds:
High molecular weight organics
Some humic substances
4. Inorganic compounds:
Some heavy metals, when bound to organic matter or particles
5. Other contaminants:
Algae
Some parasites
It's important to note that while ultrafiltration is highly effective at removing many contaminants, it does not remove contaminants like dissolved salts, organic molecules, or ions smaller than the pore size. Additional treatment methods like reverse osmosis or ion exchange may be necessary for these.

Industry Application

Operation & Maintenance

Routine maintenance is straightforward and primarily automated:

• Daily Inspection – Check TMP, flow rates, and pump condition

• Backwashing – Automatic, every 15~60 minutes, duration 60~120 seconds

• Chemical Enhanced Backwash (CEB) – Weekly, using NaClO (50~200 ppm) and/or citric acid

• CIP Cleaning – Every 1~6 months, circulating NaClO and acid solutions

• Membrane Integrity Test – Quarterly, using pressure decay or bubble point test

• Membrane Replacement – Typically every 3~5 years, depending on feed water quality and operating conditions
