<p>The process takes place in three steps, viz. 1) anaerobic degradation in a lagoon of high molecular complex organic material in the wastewater stepwise to low molecular soluble organic compounds, further to acetate, H2, CO2 and finally to biogas (methane + carbon dioxide) by a consortium of microorganisms including methanogens, 2) further conversion of low molecular compounds to biogas in an upflow or downflow anaerobic filter containing dense populations of microorganisms, mainly methanogens, and 3) final aerobic biological treatment (polishing) of the wastewater in an aerobic treatment unit.</p> |
