LUCAS® anaerobic wastewater treatment

LUCAS® anaerobic is our anaerobic wastewater treatment technology, allowing recovering biogas and energy from wastewater or bio-effluent with a high organic load.

Biogas production

UASB reactor

The biogas production reactor consists of a proprietary UASB (Upflow Anaerobic Sludge Blanket) reactor tank equipped with a three-phase separator on the top of the tank. The wastewater is fed at the reactor bottom through a distribution system. While flowing upwards through the dense sludge bed, the organic pollutants are converted into biomass and biogas.

Three-phase separator

The three-phase separator on the top of the reactor separates the biogas from the sludge and the effluent. To improve the sludge-water separation, parallel plates can be installed inside the separator to increase the settling surface area.

Advantages

  • Very compact design
  • High biogas production
  • Stable operation
  • Robustness

Applications

  • Bio-effluents with moderate organic load: 6-15 kg COD/m³
  • Food & beverage industry
  • Pulp & paper industry
