ABSTRACT:
A localized wastewater treatment system for biologically treating wastewater. Raw wastewater flows into a first operational area where a majority of solid material in the wastewater separates out of the wastewater and is retained in a solids area positioned below the first operational area. As the wastewater continues to flow into the first operational area, the wastewater overflows from the first operational area to a second operational area. Once the wastewater in the second operational area reaches a predetermined volume, a batch of the wastewater is transferred from the second operational area to a third operational area where the batch of wastewater is biologically treated by a population of microorganisms contained within a solids area located beneath the third operational area. The treated wastewater is then removed from the third operational area for dispersal.
