In general, liquid effluents, high moisture content wastes and high quality agricultural feedstocks such as sugar and starch-containing crops are preferably converted to gaseous or liquid fuels using biological routes. Developed technology for the bioconversion of biomass into energy forms falls into two categories: biogasification and bioliquefaction. Biological processes have the advantage of occurring at ambient, or relatively low (35-60°C) temperature, at atmospheric pressure, in dilute substrate, in an aqueous environment. Conversion of raw material to gas or liquid fuel is generally incomplete, leaving the non-convertible residues (organic and inorganic) in solution. Hence, biological processes potentially generate large volumes of wastewater containing significant levels of pollutants. This review briefly describes the two bioconversion process routes and then considers each process separately in relation to the characteristics, utilisation and treatment of the specific wastewaters produced by the process.
