Evaluation Of Media Influence And Practical Applications For The Use Of Static Low Density Media Filters In Domestic Wastewater Treatment, Steven Marty Bellelo
Evaluation Of Media Influence And Practical Applications For The Use Of Static Low Density Media Filters In Domestic Wastewater Treatment, Steven Marty Bellelo
LSU Master's Theses
Static Low Density Media filters have been used over the past two decades for nitrification and solids removal in high-density recirculating aquaculture systems. The SLDM filters are submerged biofilters which contain a plastic media with a density less than that of water. The media beds remain packed, or static, during operation except for periodic expansion of the bead bed during a backwash. More recently SLDM filters have been evaluated for secondary clarification of domestic wastewater where concurrent biological treatment and particulate removal occur within one unit. Recirculation is accomplished using airlifts which provide external aeration coupled with multiple pass removal …
