Issue

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.

Solution

Nereda

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

Pros

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