Anaerobic co-digestion of glycerol and wastewater derived from biodiesel manufacturing
The anaerobic co-digestion of glycerol and wastewater derived from biodiesel manufacturing, in which COD was found to be 1054 and 428 g/L, respectively, was studied in batch laboratory-scale reactors at mesophilic temperature (35 °C). Glycerol was acidified with H 3PO 4 in order to recover the alkal...

| description | The anaerobic co-digestion of glycerol and wastewater derived from biodiesel manufacturing, in which COD was found to be 1054 and 428
g/L, respectively, was studied in batch laboratory-scale reactors at mesophilic temperature (35
°C). Glycerol was acidified with H
3PO
4 in order to recover the alkaline catalyst employed in the transesterification reaction (KOH) as agricultural fertiliser (potassium phosphates). Wastewater was subjected to an electrocoagulation process in order to reduce its oil content. After mixing, the anaerobic revalorisation of the wastewater was studied employing inoculum–substrate ratios ranging from 5.02 to 1.48
