Opis

This thesis reports on the effect of different operational variables, such as anaerobic pre-treatment, the combination of algae and duckweed ponds and pond depth. Anaerobic pre-treatment was found to contribute to the reduction of area requirements for the duckweed ponds and enhanced biomass production.
