Agira™ consists of a hydrolysis tank and an aerobic bioreactor:
• The hydrolysis tank pre-treats the greasy matters in presence of lime before entering the bioreactor.
• The aerobic tank includes a patented foam cleaner and a dynamic mixer. This configuration enhances the biomass temperature (40-50°C) allowing high elimination efficiency in a reduced reactor footprint and low energy consumption.
The elimination efficiency of lipids reaches 70-90% depending on the grease quality and concentration.
Agira™ has a compact design and is perfectly adapted to degrade high loaded greasy effluents.
Treatment performances
• Total COD = 80 %
• TSS > 70 %
• Lipids > 90%
Operating conditions
• Applied charge : 3 to 5 kg HEM / m3.d
• 7,5 to 12,5 kg COD / m3.d
• Average retention time = 45 days
• COD / N/ P ratio applied : 200 / 2,5 / 0,75
• No recirculation from bioreactor to hydrolysis tank
• Energy consumption: 280 to 400 Wh / kg COD treated
Type
Two-stage intense aerobic process.
Applications
