Sewage Treatment Pilot By Nitrification - Denitrification - Dephosphatisation

Sewage Treatment Pilot By Nitrification - Denitrification - Dephosphatisation

Teaching Objectives of

• To understand the degradation phenomena of organic and chemical pollutants by the action of the micro-organisms in an aerobic environment followed by a physico-chemical treatment.
• Operation of a treatment plant according to sampling and daily analyses.
• Characterization of the nitrification - denitrification - dephosphatisation stages.

Technical specifications

• An anoxia tank with stirrer
• A ventilation tank with measurement of pH, temperature and dissolved oxygen,
• A clarification conical tank device with recuperation of the sludge
• A compressor controlled by oxygen rate measurement.
• A resistance (heater) dependant of temperature measurement,
• A dosing pump for basic solution controlled by pH measurement.
• A substrate supply pump.
• A sludge recycling pump.
• A recycling pump for the main solution
• An air flowmeter
• A liquid flowmeter for the substrat
• A laminate decanter, with adjustable plates, made of three compartments that fill themselves by overflow from the clarification device :
• A tank for the coagulation - stirred flocculation,
• A tank for the enlargement of the flakes,
• A tank for the decantation by overflow for the treated water
• A tank for the preparation of flocculation agent and coagulant (the reagents) mounted on the magnetic stirrer
