COD, BOD and Ammonium performance The graph below presents the effluent water quality from our landfill leachate treatment system. The average influent water quality is approx. 4000mg/l as COD and 1000 mg/l of ammonium. The graph below shows that the ammonium levels have dropped below 1mg/l and they have stayed below 1 mg/l. The COD has averaged out at approx. 250mg/l, however it is now slowly dropping and as diversity of bacteria is developing in the system. BOD removal is effectively 100%. The AFM® filtration systems was connect onto the end of an SBR system. The raw water from the aerated SBR tank was pumped directly into the AFM® filter. This would be impossible to do if sand was used as the filter media, however AFM® is resistant to biofouling, so this approach is acceptable. It would appear that we do not need to use humus tanks, if these results can be transferred to the tertiary treatment of sewage effluent, the financial and environmental implications will be huge.
The removal of RED Lust substances data will follow shortly. |
