Material and Structural Composition of RO Membrane Housings

1. Housing Materials

RO membrane housings are primarily constructed from:

SUS304 stainless steel (standard grade)
316/316L stainless steel (enhanced corrosion resistance for harsh environments)

Key Properties:
✔ Excellent corrosion resistance
✔ High tensile strength (withstands 2.0-2.5MPa operating pressure)
✔ Mirror-finished surfaces (inner/outer) for reduced friction loss

2. Manufacturing Methods

Type	Production Process	Advantages
Seamless	Drawn from forged blanks	Uniform wall thickness, <0.5% leakage rate
Welded	Automated orbital welding	Cost-effective, smooth weld seams (Ra≤0.8μm)

⚠ Critical Note: Seamless designs are mandatory for >2.2MPa applications.

3. Core Components

Membrane Shell
- Stainless steel body (304/316)
- Mirror-polished interior (≤0.05μm roughness)
End Caps
- Material options:
  • ABS (economical)
  • Stainless steel (high-pressure)
- Sealing System:
  • Silicone O-rings (FDA-approved)
  • 10,000+ cycle lifespan
Central Tube
- Precision-drilled (0.5-1mm holes)
- 316L stainless steel for seawater applications

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?
