Strict effluent regultations

Inefficient operation waste water treatment plant

The operations of the WWTP can be more efficient.

The new treatment plant must meet strict effluent regultations, the ambition is to have a better effluent quality than legally required. Additionally, the energy use should be reduced.



Nereda is a biological treatment technology for WWTP. Waste water is treated with micro-organisms that grow in concentrated, natural granular structures. These granules have a high biological activity, making it easy to seperate the micro-organisms from the purified water. The bacteria have an oxygen-rich exterior and an oxygen-depleted core, which allows for multiple purification processes in the same tank.

Nereda Epe


  • More energy efficient and faster than traditional treatment.
  • Less space required, there are no sedimentation tanks necessary because the granules sedimentate quickly.
