Apparatus for aerating wastewater from pressurized or gravity flow sources

摘要

An apparatus and method for single pass mass transfer of oxygen into a liquid. The apparatus comprises individual aeration modules contiguously aligned to allow continuous gravity flow liquid to be permeated with oxygen repetitively as it passes through a successive series of reaction chambers. The invention provides furthermore a novel apparatus to interject into liquids high volumes of low-pressure air to effect mass transfer of oxygen.
