  • Practical Applications of Static Low Density Media Filters for Use in the Treatment of Domestic Wastewater

    ABSTRACTIn the treatment of domestic wastewater, both biological and physical contaminant removal mechanisms must occur to facilitate compliance with NPDES permit discharge requirements. Static low density media (SLDM) filters can be used to perform both of these duties allowing for the consolidation of various unit operations into one component. Previous studies have shown that both organic and ...

  • Reduced Sludge Production in BNR Systems: Reality or Myth?

    This paper compares the performance of a pilot Modified Ludzack Ettinger (MLE) process treating degritted municipal wastewater, with full-scale activated sludge plants at two towns in Southern Ontario, namely Listowel and St. Marys. At Listowel, the MLE process achieved superior effluent quality compared to the full-scale extended aeration system at a total bioreactor HRT of 20 hours versus 48 ...

  • Types of bioremediation and their modes of action

    An Urgent Call for Change in U.S. Oil Spill Response With Bioremediation Agent Type EA* bearing out as a workable first response alternative to the use of chemical dispersants, contrasting evidence has become even clearer that dispersant use has been a huge failure. Dispersants have proven to be an inadequate response method with more and more studies showing an ...
