Filtration Process
Raw Water → Integrated Sand/Carbon Tank → Cartridge Filter → High Pressure Pump → RO Membrane → Pure Water
| 1 | Integrated Sand/Carbon | Removes sediment, chlorine, odor — all in ONE tank |
| 2 | Cartridge Filter | 5μm fine filtration, protects RO membrane |
| 3 | RO Membrane | Removes up to 99% of dissolved salts, bacteria, viruses |

FAQ
1. What does “integrated sand & carbon” mean?
The sand and carbon filtration media are combined in ONE tank instead of two separate tanks. This saves 40% floor space without reducing filtration effectiveness.
2. What is the daily output?
500 L/H equals approximately 12,000 gallons per day (about 12 tons), enough for 1,000-1,200 people.
3. Can this system fit in a shipping container?
Yes. The dimensions 950×625×1725mm fit easily in a standard 20FT container with room for operation and maintenance.
4. Does this system include a softener?
No. This system is designed for tap water or low TDS well water (TDS ≤ 1000 ppm). For high hardness water, please see our 6-tank model with softener.
5. What is the difference between 250L/H and 500L/H models?
The 500L/H model has double the output (500 vs 250 L/H), dual membranes (2 vs 1), higher power (1.5KW vs 1.1KW), and weighs 140kg vs 125kg.
6. What is the MOQ?
1 set. OEM customization available for bulk orders.
