About Renewable fuel (biodiesel) WWTP

MBR plant for the treatment of highly loaded organic wastewater

  • Cross-flow technology configuration

The highly loaded organic wastewater from a renewable fuel production and a used-fat refining plant contains 150 kg COD/m³ and only few nutrients. On the one hand the low emission limit for COD asked for a biological degradation process and on the other hand a straight forward approach with as less process components as possible was a precondition in order to keep operating costs low and process reliability high.

The central part of the MBR wastewater treatment is the membrane bioreactor with external cross-flow membranes.

The biological treatment takes place in the MBR tank. Due to the membrane, all biomass in the form of activated sludge is held back and therefore, the sludge age can be freely chosen. Ejector-aeration through the tank walls ensures aerobic degradation of organic substances, as well as prevents sludge particles from settling.

The mainly carbon-based wastewater with high amounts of methanol, glycerol and fats makes it necessary to provide a wide range of nutrients. Therefore, as base supply for nitrogen, phosphorus and potassium an agricultural fertilizer is used.
