KLARO container.one® - Containerized wastewater treatment plant

The intelligent mobile wastewater solution

KLARO container.one® is the mobile wastewater treatment plant in the standard 20 feet or 40 feet HC container. The plant was designed to be easily assembled and disassembled (plug-and-play principle). This makes the container plant particularly suitable for temporary use. It can be used in a wide variety of areas, such as traveling construction sites, worker camps, quarries or production sites with many workers. It is also suitable for remote locations such as research, tourist or military camps. Due to the installation in the container, the technology is optimally protected against all weather conditions and additionally easy to transport.

KLARO container.one® is a fully biological wastewater treatment plant that operates according to the proven KLARO One process (fully aerated SBR plant).

  • Easy to transport (standard 20 ft container)
  • Prefabricated and expandable construction
  • Quick assembly and disassembly (plug-and-play)
  • Low power consumption (13 kWh/d - 20 ft container)
  • Designed for 15 m³ (20 ft container) per day resp. 34,5 m³ (40 ft HC)
  • Modularly expandable for larger wastewater volumes

  • Suitable for permanent as well as temporary use
  • Low energy consumption
  • Low sludge quantity thanks to sludge stabilization
  • User-friendly full automation
  • Low maintenance intensity due to low-wear components
  • Quick assembly and disassembly (plug-and-play)

Areas of application


The KLARO container.one® wastewater treatment plant is designed for temporary limited use. Its concept allows the anage to be put back into operation at another site. Areas of application for the containerized wastewater treatment plant include:

  • Moving construction sites
  • Worker camps
  • Mining camps
  • Tourist camps
  • Quarries
  • Logging camps
  • Military camps
  • Research camps



Modular expansion


The modular extension or construction of the mobile wastewater treatment plants allows maximum flexibility in the design of the wastewater treatment. Thus, for larger wastewater volumes, two or more complete 20 or 40 HC feet KLARO container.one can be used, or a complete 40 feet HC container plant can be used instead. Furthermore, the container plants are available in different treatment stages. Containers are used specifically as pre-treatment stages, biological stages, secondary treatment stages or as sludge treatment stages. The design of the plants is project-specific and customer-oriented.
