Abstract
The report determines the effectiveness of an expendable electrode, direct current method for the removal of phosphates from the effluent of a secondary treatment process. The evaluation consists of measuring electrode and power consumption and phosphate removal as a function of voltage, electrode material (aluminum or iron), electrode spacing, and residence time. Batch tests were followed by continuous flow (steady-state) tests. A number of tests were run on raw sewage to evaluate the use of the system as a combined phosphate removal/bubble flotation operation.
