In Vlaardingen, the Netherlands, Delfland Water Authority – one of the 21 Dutch water boards – has officially inaugurated a new biogas upgrading unit at its ‘De Groote Lucht’ wastewater treatment plant (WWTP). Producing 1.8 million Nm3 of biogas annually from sewage sludge, this will now be upgraded to 1 million Nm3 biomethane and fed into the national gas grid.
The biomethane plant was engineered and supplied by Bright Biomethane, a subsidiary of Netherlands-based bioenergy energy technology providers HoSt. The entire biogas upgrading system is placed in a compact 40 ft container and has a capacity to upgrade 350 Nm3 per hour of ingoing biogas using proven membrane technology.
