Abstract
An oxidation ditch for circulating a waste water stream and having a channel formed by a continuous vertical outside wall extending upward from a bottom and having at least one section shaped to form a curved area into which a vertical turbine is operatively positioned and by a partition wall also extending upward from the bottom and positioned inside the outside wall with one of its ends adjacent the vertical turbine, the improvement of which comprises a baffle positioned in the channel upstream of the vertical turbine to minimize the mixing of the upstream waste water with the backwash created by the vertical turbine.
