How Hollow Fiber UF Membrane Technology Works

Hollow Fiber UF Membrane is a precision separation device that uses semi-permeable hollow fibers as the filtration medium. By applying pressure differentials, it allows only water molecules, dissolved salts, and small organics to pass through while blocking:
✔ Bacteria & viruses (0.01-0.1 micron)
✔ Turbidity & microplastics
✔ Proteins & colloids

UF membrane is made of high-strength hollow fiber PVDF. It can effectively remove suspended solids, colloids, bacteria, viruses, and large organic molecules from water while retaining mineral ions.

0.03 µm nominal pore diameter, guarantees stable permeate
Hydrophilic PVDF fibers for easy cleaning and wettability
PVDF polymeric hollow fibers for high strength and chemical resistance allows long membrane life

Key Advantages vs Conventional Filtration:

Feature	Hollow Fiber UF	Sand/Ceramic Filters
Filtration Precision	0.01 micron	1-5 micron
Pathogen Removal	99.99%+	<90%
Maintenance	Backwashable	Replaceable media

3 Core Benefits of Ultrafiltration Membrane Systems

1. Unmatched Filtration Efficiency

The precisely controlled pore structure achieves:

4-log reduction of bacteria (99.99%)
Complete removal of microplastics >0.1μm
No chemical additives required

⚠ Critical Note: Unlike RO membranes, UF preserves beneficial minerals like calcium and magnesium.

2. Energy-Saving Operation

Zero electricity consumption – Works on line pressure (10-100 psi)
<5% water waste vs 25-75% in RO systems
Carbon-neutral operation

Our 2025 case study showed 62% lower lifetime costs compared to UV disinfection systems.

3. Robust & Long-Lasting Performance

PVDF membrane material resists chemical corrosion
50,000+ gallon capacity before replacement
Simple maintenance – Just monthly backwashing

FAQs

How do I know which system is right for my home?

Choosing the perfect water treatment system depends on your specific water quality, household size, and needs. We make it easy with our 3-step process:

Water quality testing – analyze your water for contaminants, hardness, and other factors.

Personalized Consultation – Our experts recommend systems based on your results, budget, and water usage.

Customized Solution – From whole-house filtration to targeted solutions (e.g., RO for drinking water, softeners for hard water), we tailor the system to your home.

How to Measure Your Home’s Water Flow Rate？

To determine your water flow rate in gallons per minute (GPM), follow these simple steps:

Prepare for Testing:

Prepare for Testing:
- Ensure all water fixtures in your home are turned off
- Select the faucet closest to your main water supply line (usually the kitchen sink or an outdoor spigot)
Conduct the Test:
- Fully open the selected faucet
- Time how many seconds it takes to fill a 1-gallon container
- Repeat the test 2-3 times for accuracy
Calculate Your Flow Rate:
Use this formula: Flow Rate (GPM) = 60 ÷ Fill Time (seconds)Example Calculation:
- If your 1-gallon container fills in 15 seconds
- 60 ÷ 15 = 4 GPM

For more precise measurements or whole-home flow rate analysis, contact our water system specialists. We can help you determine if your current flow rate meets the requirements for any water treatment systems you’re considering.

How do I troubleshoot low water pressure from my system?

1. Check Multiple Fixtures

Test water pressure at different faucets, showers, and appliances (e.g., kitchen sink, bathroom sink, outdoor hose).

If only one fixture has low pressure, the problem is likely localized (clogged aerator, faulty valve, or pipe issue).

If all fixtures have low pressure, the issue is systemic (main supply, pressure regulator, or water heater).

2. Inspect the Aerator or Showerhead

Unscrew the faucet aerator or showerhead and check for mineral deposits, debris, or rust.

Soak it in vinegar overnight to dissolve buildup, then rinse and reattach.

3. Check the Main Shutoff Valve

Locate the main water shutoff valve (usually near the water meter or where the main line enters the house).

Ensure it’s fully open (turn clockwise to close, counterclockwise to open).

What contaminants does your water treatment system remove?

1. Activated Carbon Filters

Removes:
✅ Chlorine & chloramines
✅ Bad tastes & odors (e.g., sulfur)
✅ Volatile Organic Compounds (VOCs)
✅ Some pesticides & herbicides
❌ Does not remove heavy metals, dissolved minerals, or microbes

2. Reverse Osmosis (RO) Systems

Removes:
✅ Heavy metals (lead, arsenic, mercury, cadmium)
✅ Dissolved salts (fluoride, nitrates, sulfates)
✅ Microplastics & sediment
✅ Bacteria & viruses (if combined with UV)
✅ Chlorine & chemicals (with carbon pre-filter)
❌ May remove beneficial minerals (can be remineralized)

3. Water Softeners (Ion Exchange)

Targets:
✅ Calcium & magnesium (hardness)
✅ Low levels of iron & manganese
❌ Does not remove bacteria, chlorine, or heavy metals

4. UV Purifiers

Kills:
✅ Bacteria (E. coli, coliform)
✅ Viruses (rotavirus, hepatitis)
✅ Protozoa (Giardia, Cryptosporidium)
❌ Does not remove chemicals, metals, or sediment

5. Sediment Filters

Removes:
✅ Sand, rust, dirt
✅ Large particles & silt
❌ Does not remove dissolved contaminants

6. Whole-House Filtration Systems

Combines multiple methods (carbon + sediment + UV) for broad protection.

What’s the difference between UV, RO, and activated carbon filtration?
