<p>METHOD AND APPARATUS FOR AEROBIC SEWAGE TREATMENT Method and apparatus for converting anaerobic leaching cesspools or drainfields to an aerobic sewage treatment process by reducing the size of floc particles in the presence of an oxygen-containing gas. Sewage is continuously withdrawn from the cesspool or drainfield by a submersible pump and injected into an elongated treatment vessel under conditions of hydraulic turbulence where the sewage is moved across a sharp surface in the presence of an oxygen-containing gas so that said sewage is subjected to aerobic treatment and continuously returned to the cesspool or drainfield. Treatment continues until the cesspool or drainfield is functioning under aerobic conditions as measured by percolation of treated sewage into the surrounding soil.</p> |
