Mobile WaterTreatment Trailer Unit 500 RO CCW
Compact groundwater treatment unit with reverse osmosis · max. 500 l/h
HUTIRA MOBILE WATERTREATMENT TRAILER UNIT 500 RO CCW is designed for the treatment of groundwater. The technology is designed as a maximally simple, compact, autonomous and independent (off‑grid) solution suitable for both temporary and long‑term deployment. The unit is ideal for rapid emergency response and for areas without access to public water supply.
Basic purpose/field of use: supplying the population with drinking water in the event of a failure of the public water supply system.
Possible sources of water for treatment: groundwater from boreholes and wells; capable of treating water with higher salinity.

Water treatment process
Raw water is pumped using a self-priming process pump into the treatment unit via a flexible PVC hose with suction basket. A frequency converter regulates flow. Flow, pressure, and volume sensors are installed at the pump discharge. Sodium hypochlorite (NaClO) is dosed for pre-disinfection and partial oxidation. The water then passes through a disc filter (gross mechanical impurities), an anthracite filter (turbidity and iron), and a Pyrolox filter (manganese and remaining Fe). Two parallel activated carbon filters then remove excess chlorine, heavy metals, and organic residues. The pre-treated water enters the reverse osmosis station producing 500 l/h of drinking water. Final hygienisation is achieved by NaClO dosing at the outlet.
The technology is controlled by a simple control system and requires the presence of trained operators.
