About Biological leachate WWTP

  • Cross-flow technology configuration
  • Membrane material: ceramic MFR (0,2 µm)

Due to their high contaminant concentration, landfill leachate poses a great environmental problem. An efficient and environmentally sound process has been developed and commissioned in Austria in 1994.

The raw leachate contains 25.000 mg/l of COD and 4.000 mg/l of Ammonia-N, but also heavy metals are exceeding the threshold limits.

The MBR consist of denitrification and nitrification tanks and a connected external ceramic cross-flow membrane unit. Injector-aeration through the tank walls ensures aerobic degradation of organic substances an ammonia, as well as prevents sludge particles from settling.
