Leveraging municipal wastewater resources into biogas energy provides economic and environmental benefits for community and business.
Understanding the biogas process
Anaerobic Digestion is the biological process that converts wastewater and organic matter into biogas for economic and operational use.
STEP 1 Municipal wastewater is sent to wastewater treatment plant.
STEP 2 The Wastewater Treatment plant treats the wastewater and produces sewage sludge.
STEP 3 Multi Feedstock Anareobic Digestion and Biogas Storage - Sewer sludge is mixed and anaerobically digested over 2-3 weeks. Agricultural, industrial organic and municipal waste can be added to this process to boost biogas production. Raw biogas is stored in biogas storage holders.
STEP 4 Electricity and Heat Generator and Distribution - Raw biogas is sent to the generator to produce electricity and heat that is then used to power the plant or is distributed to the electricity grid for use by homes and businesses.
STEP 5 Biogas Purification, Liquefaction and Distribution - Raw biogas is dehydrated and impurities removed to produce biomethane. Biomethane is upgraded and 5a) bioCNG is injected into the natural gas network or 5b) undergoes biomethane liquefaction that converts it into bioLNG. BioLNG is transported to a BioLNG station.
STEP 6 BioLNG and BioCNG - Local, green and renewable fuel source available for commercial use that offers significant savings over diesel and petrol.
