Analysis Of Mathematical Models Using Non-Linear Ordinary Differential Equations With Application To Activated Sludge Process, Salman Saud Alsaeed

University of Wollongong Thesis Collection 2017+

The activated sludge process has been successfully applied to treat both municipal sewage and industrial wastewater since the beginning of the 20th century. Today, across the world, more than 90% of modern municipal water treatment plants use the activated sludge process. The process consists of three major components: an aeration tank, a clarification or settling tank, and a method for returning some activated sludge to the input line. The procedure’s effectiveness is contingent on employing microorganisms, which consume the organic contaminants in the wastewater and generate new microorganisms. This self-replication means that, in theory, the process may continue indefinitely. The …
