Problem / opportunity
- 150,000 hectolitres of beer produced per year
- Regulatory obligation to purify effluents:
- 45,000 m3 / year
- 310 Tons COD / year
Solution :
- Methanisation of effluents using VALBIO METHACORE® technology – 2 digesters of 125 m3
- Biogas valorized in a boiler to produce hot water
- In service since April 2013
Result of methanisation
- 135,000 m3 of biogas produced per year
- 800,000 kWh / year
- Purification efficiency:
- COD: 90% BOD: 90%
