Taiwan biogas plant advantages from Landia mixing system

เพรสเชอร์เกจ in Hualien County on the east coast of Taiwan is the primary biogas plant in the country to make use of livestock manure as its feedstock, using a digester mixing system made by Landia.
The plant options six of Landia’s externally mounted GasMix techniques, which enhance biogas yields. The 18.5 kw units are helping generate what will amount to approximately 876,000 kWh of electricity every year for the Taipower grid (equivalent to the electricity capacity of 250 households) from 300 tonnes of livestock manure wastewater daily within the breeding space of Sanmin, Yuli Town where eight livestock farms are house to almost 10,000 pigs and near seven hundred cows.
Benefitting from the Landia Chopper Pump, the digester mixing system draws thick liquid from the bottom of the 6,000 m3 tank, where solids are chopped to speed up the digestion process and prevent clogging of pipes and nozzles. In the primary stage of the mixing process, the livestock wastewater is injected into the higher half of the digester, while biogas is aspirated from the highest of the tank and blended into the liquid. This reduces buoyancy at the surface of the liquid, and the rising gas bubbles continue to combine after the pumps are switched off.
