Problem / opportunity:
- 15 million bottles / year
- Regulatory obligation to purify effluents:
- 12,000 m3 / year
- 80 Tons COD / year
Solution:
Methanisation of effluents using VALBIO METHACORE® technology – 1 digester of 50 m3
Biogas valorized in a boiler to produce hot water
Aerobic finishing treatment
In operation since 2010
Results of methanisation:
- 135,000 m3 of biogas produced per year
- 800,000 kWh / year
- Purification efficiency:
- DCO: 90% DBO: 90%
