Activated Sludge Wastewater Treatment Pilot

This pilot presents the process for eliminating carbonaceous, nitrogenous, and phosphorous pollution by microbiological means. It operates by contacting the water to be treated with a bacterial floc in the presence of O₂, followed by a floc separation phase. This is an 'activated sludge' treatment process.

Educational Objectives: Achieve maximum purification efficiency by varying: mass and volumetric load, sludge age, biofloculation quality, aeration.
