as Gary says, you need to know the composition of the wastewater first, and then you should pay attention to the available pretreatment processes. To mention API or Tilted Plate separators with coalescing material, followed by a DAF with emulsion breaker dosing should remove the bulk of your organic load and reduce the needed volume for the biological treatment and oxygenation capacity. Note that you may need to dose nutrients N&P for a balanced activated sludge process.
