A system, method and apparatus for treating wastewater containing biodegradable material wherein a submerged stand alone perforated cylinder reactor pod containing aerobic bacterial growth media and a draft tube with air pressure induced pumping action creates a spray or splash pattern so as to recirculated aerated liquor through the media and also to the area surrounding the cylinder pod. Free interchange of mixed and unmixed liquor is provided via the perforations in the cylindrical pod wall. Provision is also made for back flushing the media and returning mixed liquor to an area remote from the reactor pod.
