From a puddle to drinking water.
Terrawat™ RO is a compact field unit for preparing water from unknown or high-risk surface sources. The whole system fits in a tactical backpack and runs on battery.
Six treatment stages.
- 01Coarse mechanical filter – Captures sand, rust and organic debris.
- 02Activated carbon + mixbed – Organics, pesticides, chlorine and dissolved ions.
- 035 µm mechanical filter – Fine particles and microplastics, membrane protection.
- 04Reverse osmosis – Typical retention of 95–99 % of dissolved solids.
- 05UV-C disinfection 254 nm – Inactivates bacteria, viruses and protozoa without chemicals.
- 06Taste polishing – Fine carbon cartridge for taste and odour.
A water plant in a backpack
The system sits in a corrosion-protected steel case fixed inside a tactical backpack. Cordura, MOLLE, water-resistant design and inner padding protect it from abrasion, vibration and impact.
Double microbiological barrier
The RO membrane limits the passage of microorganisms and the UV-C stage then inactivates any residual biological load. The result is clear, odourless water with greatly reduced salts, heavy metals, nitrates and pesticides.
For armed forces, rescue and humanitarian missions
Built for military and special units, rescue services, humanitarian missions, expeditions and emergency water supply. Battery operation allows use away from any power grid.
Input and output in numbers.
Conductivity
3 920 → 151 µS/cm−96 %Suspended solids
35 → 0,5 mg/l−98 %pH
7,8 → 6,9–Values from the manufacturer’s model analysis. Actual suitability for drinking depends on the source water, operation and maintenance. For unknown or serious contamination the output must be verified by laboratory analysis. Max. input conductivity 4,000 µS/cm; not intended for seawater.
