High-Temperature Chemical-Resistant UF System – Durable Filtration for Harsh Industrial Applications

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

Standard ultrafiltration systems have their limits. Feed them water that's too hot, too acidic, too alkaline, or too chemically aggressive, and they struggle. Membranes degrade. Seals fail. Performance drops. What works for clean surface water or RO pretreatment simply doesn't hold up in chemical plants, dye houses, plating facilities, or pharmaceutical wastewater applications.

These environments demand a different kind of UF system. One built with materials that can withstand high temperatures, extreme pH levels, and aggressive chemical streams. A system that doesn't just tolerate these conditions but operates reliably for years under them.

The DAGYEE High-Temperature Chemical-Resistant UF System is engineered specifically for these applications. With upgraded membrane chemistry, specialized seals and gaskets, and a design that handles feed temperatures up to 60°C and pH from 1 to 14, this system thrives where standard UF systems would fail.

If you're treating wastewater from chemical synthesis, dye manufacturing, metal finishing, or pharmaceutical production, this is the UF system that delivers consistent performance day in, day out.

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

Step 1: Feed Conditioning (If Needed)
Depending on the feed quality, the system may include upstream cooling, pH adjustment, or oil removal before the UF membranes. Not every application needs all of these—we design based on your actual feed water analysis.

Step 2: Pre-Filtration
Coarse screens or cartridge filters remove large debris and particles. The pre-filtration is sized to handle high solids loading and is easy to clean or replace.

Step 3: Ultrafiltration
The heart of the system. PVDF or PES hollow fiber membranes handle the high-temperature, high-chemical-load feed. The filtration process removes suspended solids, colloids, bacteria, and high molecular weight organics.

Step 4: Automated Cleaning
The system includes specialized cleaning protocols for high-temperature operation and aggressive fouling. Automated CIP (Clean-in-Place) and CEB (Chemical Enhanced Backwash) cycles run on a schedule or triggered by TMP rise. Cleaning agents are selected for compatibility with the feed stream contaminants.

Step 5: Permeate Discharge
Clean permeate exits the system, ready for reuse, discharge, or downstream treatment. The concentrated reject stream goes to further processing or disposal.

Step 6: Temperature Monitoring
Continuous temperature monitoring ensures the system operates within safe limits. Alarms trigger if temperature exceeds setpoints, protecting the membranes from damage.

What This System Removes

The Compact UF System is a physical barrier. It removes anything larger than its pore size. Here's what that means in practical terms:

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
