Wastewater treatment degreasing unit Agira™

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 • Treatment of grease from municipal and agro-food industries wastewaters • Cesspits content treatment • Primary sludge stabilization
