The new Pushige Biomass Energy Center in Hualien County on the east coast of Taiwan is the primary biogas plant within the country to use livestock manure as its feedstock, using a digester mixing system made by Landia.
Dark of Landia’s externally mounted GasMix systems, which enhance biogas yields. The 18.5 kw models are serving to generate what will amount to roughly 876,000 kWh of electricity each year for the Taipower grid (equivalent to the electrical energy capability of 250 households) from 300 tonnes of livestock manure wastewater every day in the breeding area of Sanmin, Yuli Town where eight livestock farms are house to nearly 10,000 pigs and close to 700 cows.
Benefitting from the Landia Chopper Pump, the digester mixing system draws thick liquid from the underside of the 6,000 m3 tank, where solids are chopped to speed up the digestion process and stop clogging of pipes and nozzles. In the primary stage of the mixing process, the livestock wastewater is injected into the upper half of the digester, while biogas is aspirated from the highest of the tank and mixed into the liquid. This reduces buoyancy on the surface of the liquid, and the rising gasoline bubbles proceed to combine after the pumps are switched off.
