Bangna Starch Wastewater Treatment and Biogas Utilization Project (300084)(ID: 103000000002351)
South Pole Carbon Asset Management Ltd.
The proposed project activity consists of the installation of an upflow anaerobic sludge blanket technology (UASB) biogas reactor, tapioca pulp treatment and power generation (2.85 MWel gas engine (3*0,95 MW) plus future expansion of up to 1.4 MWel) at an existing starch manufacturing plant. The project replaces the existing wastewater treatment practice (open lagoon system) and thus avoids the release of methane into the atmosphere that results from the anaerobic digestion of the organic content in the wastewater treated in the lagoon system (anaerobic conditions, leading to methane generation within the lagoon are the result of lagoon depth (> 2m) and an average atmospheric temperature of about 28°C). The biogas reactor system is expected to handle a wastewater flow rate of 3,750 m3/day and an expected average COD concentration of 18.000 mg/l
