Abstract:

The cassava starch production in India is mainly concentrated in small to medium scale factories, which generates 30,000 to 40,000 liters of effluent per tonne of sago produced. The effluent from these industries is acidic and highly organic in nature having COD of 5000 to 7000 mg/l during the season and 1000 to 5000 during the off-season. These effluents pose a serious threat to the environment and quality of life in the both rural and cities. Since the treatment of sago factory effluent through the normal biogas plant with 30 to 55 days retention period is very costly, attempts have been made to treat them through high rate biomethanation reactor with several hours of retention period. In the batch digestion of 4-5 week period there was no gas production at all from the sago waste water, when it was not neutralized and not added with inoculum without any addition of media. The maximum gas production of 34.5 Liters at 4.35 m3/kg TS reduced with biogas production of 1.01/l of feed in the digestion with the weekly addition of 25,10 and 5 percent of inoculum respectively over the first three weeks without any addition of media. The performance of hybrid biomethanation reactor with the packing media of PVC pall rings was designed and performance was studied under different retention period. The specific gas production was 723l/kg TS and 909l/kg VS in PVC pall rings media reactor.
