Biological leachate WWTP
MBR/external cross-flow/ejector aeration - cross-flow technology configuration
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.
