1. A bioreactor for a water treatment system, the bioreactor comprising:
a tank configured to receive an influent liquid;
a separator structure positioned in the tank, the separator structure having a frustoconical shape and defining a lower opening proximal to or at a bottom of the separator structure, wherein an interior of the separator structure is in communication with the tank, external to the separator structure, at least via the opening;
an aeration vent positioned proximal to a bottom of the tank and configured to direct air into the tank, but not directly into the interior of the separator structure;
an air line connected to the aeration vent;
an effluent outlet communicating with the interior of the separator structure, proximal to a top of the separator structure, wherein a relatively clean effluent liquid, in comparison to the influent liquid, exits from the separator structure via the effluent outlet; and
a stand having a base configured to receive the separator structure, wherein the stand is supported on the bottom of the tank, wherein the base of the stand is polygonal in shape and has a maximum cross-sectional dimension that is smaller than a maximum diameter of the separator structure, such that the separator structure is configured to be seated into the stand.
