- The activated sludge process presently represents the most widespread technology for wastewater purification.
- The invention of the activated sludge process is connected with the efforts of British and American engineers at the end of the last century to intensify biological purification in fixed-film systems.
: wastewater is routed through a series of channels constructed in the aeration basin.
Wastewater Flows through as a plug & is treated as it winds its way through the tank.
As the wastewater goes through the system, BOD and organics concentration are greatly reduced.
Variations to this method include: adding return sludge and/or in decreasing amounts at various locations along length of the tank; wastewater BOD is reduced as it passes through tank, and air requirements and number of bacteria required also decrease accordingly.
