Biogas in WWTP: maximisation with OFMSW co-digestion
Biogas in WWTP is the most underused operational opportunity in Spain’s water sector. Most plants with anaerobic digestion operate with VS removal of 35-50% digesting only primary and secondary sludge, when they could reach 45-65% by co-digesting with the organic fraction of municipal solid waste (OFMSW). Well-managed co-digestion raises biogas production, reduces the dewatered sludge […]
