The first Grundfos BioBooster mobile waste water treatment plant was installed this week
This week Grundfos BioBooster delivered a containerized treatment plant to Viborg municipality in Denmark. The treatment plant is located in Bjerregrav and will treat a volume of 1000 person equivalents. The plant will run as a trial site for a six-month period. Bjerregrav is one of many small scale municipal treatment plants scattered across Denmark, which constitute a potential market for Grundfos BioBooster.
If the Grundfos BioBooster is a success, Viborg municipality expects savings in the amount of 50 million DKK by replacing 18 purification plants with the mobile Grundfos BioBooster.
The savings are primarily to be found in the flexibility the BioBooster provides. A BioBooster plant processes water 10 to 20 times faster than an ordinary plant. The fact that BioBooster is also very compact underlines the flexibility, the plant can be placed anywhere, thus minimizing infrastructure investments.
The technology
The essence of the technology in the BioBooster is the MBR (Membrane Biological Reactor). The reactors, where the actual process occurs, are five meter long pipes with a diameter of 40 cm.
The pipes are filled with active biomass, bacteria, which eliminates contaminants in the water. The bacteria feed on, for example, the organic matter or nitrogen in the water.
Because of the pressure in the reactor, water molecules are pressed through the small openings in the membranes (filter). The openings are so small that only water can penetrate, while the impurities (eg. Bacterium) stay in the filter.
The plant is built into a container that serves as a building block. If greater capacity is wanted, you simply put more building blocks (containers) together.
In Bjerregrav the system consists of five 20-foot containers and has a capacity of 10 m3/hour. The five containers consist of a control container, a pretreatment container, a supply container, a container with 16 reactors and an oxygen free tank where nitrogen and phosphorus are biologically converted.
By adding a container with 16 more reactors the capacity can be doubled.
