Softener Feature: Why It Matters

The Problem

High hardness water (high calcium & magnesium) causes:

  • ❌ Scale buildup on RO membranes (white crusty deposits)
  • ❌ Reduced water output
  • ❌ Increased pressure drop across membranes
  • ❌ Frequent chemical cleaning
  • ❌ Shortened membrane life (1-1.5 years)

The Solution

Our system includes a built-in water softener (resin tank) :

Raw Water HardnessNeed Softener?
≤ 100 mg/LNo — standard RO is fine
100 – 300 mg/LRecommended
> 300 mg/LStrongly Recommended

Result: Outlet hardness ≤ 50 mg/L · Membrane life extended by 30-50% · Reduced cleaning frequency

How the Softener Works

  1. Raw water passes through the resin tank
  2. Resin beads attract and hold calcium (Ca²⁺) and magnesium (Mg²⁺) ions
  3. Softened water flows to RO membranes (scale-free)
  4. When resin is saturated, regeneration with salt solution restores it
  5. Brine tank provides salt for regeneration (manual or automatic)

FAQ

1. What is the daily output?
5000 L/H equals approximately 120,000 gallons per day (about 120 tons), enough for 10,000-12,000 people.

2. What is the advantage of 8040 membranes over 4040?
Five 8040 membranes provide 186 m² of membrane area — 29% more than twenty 4040 membranes (144 m²). Fewer components (5 housings vs 20), less piping, lower leak risk, and much easier maintenance.

3. Does this system include a softener?
No. This is a standard 3-tank system (sand + carbon + cartridge) for tap water or low TDS well water. For high hardness water, we recommend our 4-tank model with softener.

4. What type of water can this system handle?
Tap water, well water, groundwater with TDS up to 2000 ppm and low to medium hardness.

5. What voltage is required?
Standard 380V / 50Hz (3-phase). 220V / 60Hz is available upon request.

6. How much floor space is required?
Approximately 10-12 square meters.

7. How long does installation take?
About 1-2 days. The system comes pre-assembled — just connect water inlet, drain, and power.

8. What is the MOQ?
1 set. OEM customization available for bulk orders.
