BIOTIM® UASB reactor

The BIOTIM® UASB (Upflow Anaerobic Sludge Blanket) reactor is particularly adapted for anaerobic treatment of high loaded wastewaters.

Biogas production

The BIOTIM® UASB is a 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. This biogas creates a more turbulent area above the sludge bed, called the sludge blanket.

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.

Applications

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

Advantages

  • High COD removal efficiency
  • High gas production
  • Low sludge production
  • Stable operation
  • Robustness
