Wastewater Treatment Pilot

This pilot allows the study of the processes used in an activated sludge wastewater treatment plant. Educational Objectives: Understand the phenomena of degradation of chemical and organic pollutants by the action of micro-organisms in aerobic medium, followed by physico-chemical treatment. Operation of a plant based on daily sampling and analyses. Learn about Wastewater Treatment Pilot specifications for optimal educational outcomes.. Characterization of nitrification, denitrification, and dephosphatation stages.

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.
