1. A wastewater treatment system, comprising:
a wastewater inlet for receipt and flow of wastewater therethrough, the wastewater inlet having a first end and a second end, the first end of the wastewater inlet configured for fluid communication with a wastewater source; a wastewater outlet for flow and discharge of oxygenated wastewater therethrough, the wastewater outlet having a first end and a second end, the second end of the wastewater outlet configured for fluid communication with the wastewater source; an oxygen source; an oxygenator operably coupled to the oxygen source to permit oxygen from the oxygen source to be introduced to the oxygenator, the oxygenator comprising an oxygenator inlet, an oxygenator outlet, and a container, the container comprising an inverse conically shaped portion configured to have a first end tapering towards a larger second end, the inlet of the oxygenator operably connected to the second end of the wastewater inlet and the first end of the container, the outlet of the oxygenator operably connected to the first end of the wastewater outlet and the second end of the container, wherein when the wastewater flows through and is oxygenated by the oxygenator, a level of dissolved oxygen in the oxygenated wastewater increases; a recirculation mechanism comprising a recirculation channel fluidly coupled to the wastewater inlet and the wastewater outlet, wherein the recirculation channel is configured to allow oxygenated wastewater to flow therethrough; and a controller electrically connected to the recirculation mechanism and capable of altering the flow of oxygenated wastewater through the recirculation mechanism. |
