120 m³/Day Containerized RO System Brings Clean Drinking Water to a Remote village
Project Location: Mongolia
Population Served: Approximately 4,000 - 5,000 residents
System Capacity: 120 m³/day (5 m³/hour)
Commissioning Date: December 2025
1.The Challenge: Water Scarcity in a High-Altitude Environment
The highland village of Ban Nam Yen, located at an altitude of over 1,500 meters, faced a severe water crisis. Existing infrastructure was non-existent, and the village's isolation—a 6-hour drive on unpaved roads from the nearest city—made delivering bottled water or transporting fuel for diesel generators economically unfeasible.
The community required a reliable, low-maintenance solution that could:
1)Treat variable raw water quality to meet WHO drinking water standards.
2)Withstand cool temperatures and rugged terrain.
3)Be installed quickly without the need for heavy construction equipment.
2. The Solution: A Self-Contained RO system
To meet these specific needs, a custom-engineered 20-foot containerized reverse osmosis system was designed and deployed. The unit was prefabricated and tested in a manufacturing facility before being trucked to the site, ensuring a "plug-and-play" installation.
Technical Specifications:
| Parameter | Specification |
|---|---|
| Model | Containerized Brackish Water RO Unit |
| Dimensions | 1 x 20 ft Container |
| Permeate Flow | 120 m³/day (at 25°C) |
| Recovery Rate | 65% |
| Raw Water Source | Deep well water (conductivity: 1,500us/cm) |
| Product Water Quality |
<5us/cm (meets WHO potable standards) |
3.Process Train:
Pretreatment: Multimedia Filtration , Activated carbon filter and Antiscalant Dosing (to prevent silica scaling).
Membranes: High-rejection brackish water RO membranes arranged in a single array.
Post-treatment: UV sterilization in the clean water tank line.
4.Impact and Benefits
Six months after commissioning, the system has provided the community Reliable Access to Safe Water: The plant consistently produces 120 m³ per day, providing approximately 25-30 liters per person per day for domestic use, far exceeding the community"s previous consumption .
