Abstract
An orbital wastewater treatment system includes a tank and a partition disposed in the tank to define a pair of channels in the tank. The tank has a turning wall bounding contiguous portions of the channels. The partition has an end spaced from the turning wall, whereby the channels communicate with one another. A driven shaft is disposed vertically in the tank between the end of the partition and the turning wall. The driven shaft is provided at an upper end with a surface aerator and at a lower end with a horizontal impeller. At least one baffle member is disposed in the tank partially about a lower end of the shaft including the impeller.
