Integrated solid waste and wastewater treatment for energy recovery

A system for the integrated sewage and municipal solid waste management has been developed at the University of Padova in order to achieve the following strategic aims: a) reduction of putrescible organics to be landfilled with consequent emissions minimisation; b) reduction of the problems related to large centralised wastewater treatment facilities; c) production of methane from anaerobic digestion as an alternative energy source.

The system, named AQUANOVA, is based on the home collection of kitchen waste and separation (using a special no mix toilet) of sewage components into three streams - greywater, yellow water (urine) and brown water (faecal matter)- and subsequent differentiate treatment. Greywater and a part of the yellow water are treated in a wetland system; Brownwater is codigested with shredded kitchen waste, under anaerobic thermophilic conditions, to obtain methane as alternative source of energy. A series of batch and labscale experiments have been carried out on anaerobic codigestion of kitchen waste with different sewage fractions in order to investigate the technical feasibility of the process and the optimal operation conditions. Tests are conducted in batch continuous reactors. The methane production of different mixtures of kitchen waste and sewage components proved to be higher than the production of the individual material alone and the addition to the mixtures of yellow water has evidenced positive effects.
