8040 Membrane Advantage
2 x 8040 vs 8 x 4040 Comparison
| Comparison | 8 x 4040 System | 2 x 8040 System (This Model) |
|---|---|---|
| Number of membranes | 8 pieces | 2 pieces |
| Total membrane area | 57.6 m² | 74.4 m² (29% more) |
| Membrane housings | 8 | 2 |
| Piping connections | Many | Fewer |
| Leak risk | Higher | Lower |
| Maintenance | More complex | Simpler |
| Installation time | Longer | Shorter |

Advantage: Fewer components means less maintenance, lower leak risk, easier installation, and larger total membrane area.
Chemical Dosing System: Why It Matters
The Problem
High scaling potential water (high silica, high hardness, high TDS) causes:
- ❌ Scale buildup on RO membranes
- ❌ Reduced water output
- ❌ Increased pressure drop
- ❌ Frequent chemical cleaning
- ❌ Shortened membrane life
The Solution
Our system includes a chemical dosing system:
| Feature | Benefit |
|---|---|
| Anti-scalant injection | Prevents scale formation on membrane surface |
| Adjustable dosing rate | Customizable for different water qualities |
| Dosing tank + pump complete | Ready to use, no additional components needed |
Result: Extended membrane life · Reduced cleaning frequency · Stable operation
When to Choose Dosing System vs Softener
| Water Characteristic | Recommended Solution |
|---|---|
| High hardness (Ca²⁺, Mg²⁺) | Softener |
| High silica, high TDS, complex scaling potential | Chemical Dosing System |
| Limited space, lower budget | Chemical Dosing System |
| Both hardness and scaling potential | Softener + Dosing |
| Want fewer components | Chemical Dosing System |
This system includes a chemical dosing system — ideal for challenging feed water where a softener is not sufficient or practical, while using only 2 x 8040 membranes for simplicity.

FAQ
1. What is the daily output?
2000 L/H equals approximately 48,000 gallons per day (about 48 tons), enough for 4,000-5,000 people.
2. What is the advantage of 8040 membranes over 4040?
Two 8040 membranes provide 74.4 m² of membrane area — 29% more than eight 4040 membranes (57.6 m²). Fewer components (2 housings vs 8), less piping, lower leak risk, and easier maintenance.
3. What is the chemical dosing system for?
It injects anti-scalant into the feed water before the RO membranes. This prevents scale formation, extends membrane life, and reduces cleaning frequency.
4. Do I need to buy the chemical separately?
Yes. Anti-scalant is not included. We can recommend suitable products based on your water quality.
5. How often do I need to refill the dosing tank?
Depending on your water flow and dosing rate, a 40L tank typically lasts 2-4 weeks. We can calculate exact consumption based on your operating hours.
6. What is the difference between this and the softener model?
Softener removes hardness ions (Ca²⁺, Mg²⁺). Dosing system injects anti-scalant to prevent scale. For high silica or complex water, dosing is more effective. For very high hardness, a softener may still be needed.
7. What voltage is required?
Standard 380V / 50Hz (3-phase). 220V / 60Hz is available upon request.
8. How long does installation take?
About 4 hours. The system comes pre-assembled — just connect water inlet, drain, and power.
9. What is the MOQ?
1 set. OEM customization available for bulk orders.
