The Diffusion Bar Aerobic Treatment Plant ("DBATP") is a device which processes sewage for buildings which are not connected to municipal sewer lines. It is comprised of a pre-tank which captures trash and allows anaerobic microorganisms to begin breaking down the sewage, an aerobic tank where aerobic microorganisms digest the sewage, and a post-tank which acts as a gravity separating clarifier in which solid particulate contaminants settle downward, leaving a clean effluent for discharge to the environment. The aerobic tank encompasses a diffusion bar, which emits air bubbles that activate and stimulate the aerobic microorganisms. In the preferred embodiment, the diffusion bar is located away from the post-tank, and it emits air bubbles near the bottom of the aerobic tank and is further comprised of one or more deflector plates, which break the air bubbles from the diffusion bar into smaller micro-bubbles in order to improve oxygen entrainment and, thereby, enhance the cleaning effect of the aerobic microorganisms. The deflector plates also increase turbulence and stirring of the sewage in the aerobic tank, which further improves the cleaning function of this stage. The improved design of the diffusion bar in the DBATP markedly upgrades the performance of the aerobic sewage treatment process.
