Filtration Process
Raw Water → Sand Filter → Carbon Filter → Cartridge Filter → High Pressure Pump → RO Membranes (8040×2) → Pure Water
| Stage | Component | Function |
|---|---|---|
| 1 | Sand Filter | Removes sediment, rust, suspended solids |
| 2 | Carbon Filter | Removes chlorine, odor, organic matter |
| 3 | Cartridge Filter | 5μm fine filtration, protects RO membranes |
| 4 | RO Membranes (8040×2) | Removes up to 99% of dissolved salts, bacteria, viruses |

FAQ
1. What is the daily output?
4000 L/H equals approximately 96,000 gallons per day (about 96 tons), enough for 8,000-10,000 people.
2. What is the advantage of 8040 membranes over 4040?
Two 8040 membranes provide 74.4 m² of membrane area with only 2 housings. A comparable 4040 system would require 16 housings. This means: fewer components, 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 8-10 square meters.
7. How long does installation take?
About 4-6 hours. 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.
