Softener + Dosing: Why Dual Protection?
The Problem
High hardness + high scaling potential water causes:
- ❌ Scale buildup on RO membranes
- ❌ Reduced water output
- ❌ Increased pressure drop
- ❌ Frequent chemical cleaning
- ❌ Shortened membrane life
The Solution: Dual Protection
| Protection Layer | Function |
|---|---|
| Softener | Removes 90-95% of hardness ions (Ca²⁺, Mg²⁺) upfront |
| Dosing System | Injects anti-scalant to handle remaining hardness + silica + other scale-forming compounds |
Result: Maximum scaling prevention · Longest membrane life · Lowest operating cost
When to Use Dual Protection
| Water Characteristic | Recommended Solution |
|---|---|
| Low hardness (< 100 mg/L) | Standard RO |
| Medium hardness (100-300 mg/L) | Softener only |
| High hardness (> 300 mg/L) | Softener |
| High silica or complex scaling potential | Dosing only |
| High hardness + High scaling potential | Softener + Dosing (This System) |

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. Why do I need both a softener and a dosing system?
Softener removes most hardness ions (90-95%). Dosing system injects anti-scalant to handle the remaining hardness plus silica and other scale-forming compounds. Together, they provide maximum protection for the most challenging water sources.
3. How does the softener work?
The resin tank contains special resin beads that attract and hold calcium (Ca²⁺) and magnesium (Mg²⁺) ions, removing them from the water. When saturated, regeneration with salt solution restores it.
4. How does the dosing system work?
The dosing pump injects a small amount of anti-scalant chemical into the feed water. This chemical prevents scale crystals from forming on the membrane surface.
5. What type of water is this system designed for?
High hardness well water, borehole water, groundwater with complex scaling potential (high hardness + high silica + high TDS). The dual protection system handles the most challenging feed water conditions.
6. What voltage options are available?
Both 220V / 50Hz and 380V / 50Hz are available. Please specify your requirement when ordering.
7. How often do I need to regenerate the softener?
Typically every 2-5 days, depending on raw water hardness and flow rate.
8. How often do I need to refill the dosing tank?
A 40L tank typically lasts 2-4 weeks, depending on flow rate and dosing rate.
9. What is the MOQ?
1 set. OEM customization available for bulk orders.
10. How long does installation take?
About 4-6 hours. The system comes pre-assembled — just connect water inlet, drain, and power.
