Plug & play units to improve capacity of existing biological plants. The reactors contains biomedia as well as an energy efficient aerator.

The unit can be placed direct into a concrete or pond plant.

The footprint of each unit is 2,2 x 2,2 m, rectangular or Ø 2,2 round.

Height and in/out-lets are individually designed. The reactor can be mounted as an individual unit or in groups as a wall or other configurations.

The aerator is giving sufficient oxygen for the operation of the unit. The cleaning capacity of unit depends on the BOD, temperature and a active biofilm surface of the unit.

This concept is a cheap and fast alternative to expansion of the cleaning capacity using traditional technological concepts.
