摘要

Apparatus is provided for removing pollutants from waste water. An activated sludge system is disclosed comprising generally a two tank system in which uniquely designed and positioned air diffusion and liquor transfer systems are utilized in combination with improved tank designs to effectively carry waste water through aeration and clarification stages to provide a fluid of a purification level not heretofore attainable from small activated sludge systems.
