Carbon removal

In the mobile purification plant, the first stage is a biosorption system which will withdraw maximum carbon in the primary purification stage, where the gas potential is greatest.
Larger biogas production gives more green energy.
The biosorption system consists of a tank with media on which bacteria can grow followed by a filter for capturing the organic substances from the wastewater and the bacteria.
The bacteria capture the organic matter dissolved in the wastewater and convert it into bacterial biomass which can be captured in a filter.
The withdrawal of organic matter can be controlled on-line, taking into account the need for carbon in the biological stage.

Drum filter seen from the outside. The drum with the filter cloth is protected by a metal cap.


Inside the drum filter, sludge (organic matter) is flushed from the filter cloth and down into a ridge, where it is channeled to later biogas production.
