Systems improvement and energy savings program for the existing conventional extended aerobic treatment of domestic wastewater in compliance of DAO 2016-08 new general effluent regulations
Maceda M.
Topic:
Wastewater treatment
This is a system improvement and energy savings program for a Sewage Treatment Plant treating wastewater coming from a shopping mall operation. Wastewater from shopping mall is considered domestic wastewater, which needs a big volume of water, and produced big amount of wastewater. Generators of...Read more

Use of a two-stage MBBR system for medium-strength dairy wastewater treatment
Katsara A., Iliopoulou A., Zkeri E., Aloupi M., Fountoulakis M., (Corresponding) Stasinakis A.
Topic:
Wastewater treatment
A two-stage Moving Bed Biofilm Reactor (MBBR) system consisting of a methanogenic and an aerobic reactor in series was used for medium strength dairy wastewater treatment. An energy analysis was conducted for the methanogenic MBBR to investigate its autonomy and its potential to act as a...Read more

Condensate originating from household food waste as a substrate for Microbial Fuel Cells
Kamperidis T., Pandis P., Vlachaki E., (Corresponding) Tremouli A., Lyberatos G.
Topic:
Environmental biotechnology and bioenergy
A microbial fuel cell (MFC) is a bioreactor that converts the chemical energy of the bonds of organic compounds to electrical energy, through the catalytic reactions of microorganisms. Under anaerobic conditions various substrates have been examined using MFC technology. This study examines the...Read more

The potential impact of an implementation of microalgae-based wastewater treatment on the energy balance of a municipal WWTP in Central Europe
(Corresponding) Hasport N., Krahe D., Kuchendorf C., Theilen U., Beier S.
Topic:
Environmental biotechnology and bioenergy
The integration of a photobioreactor for wastewater treatment by microalgae is proposed as a future alternative for cost-efficient and environmentally friendly nitrogen and phosphorous removal in municipal WWTPs. The high growth rates and higher biogas yields (compared to conventional sewage sludge...Read more

Energy recovery from urea in decentralised wastewater streams
Asiain-Mira R., Zamora P., Rogalla F., Monsalvo V., (Corresponding) Torrente-Murciano L.
Topic:
Water, energy and/or food nexus
This work presents the design of a new process that enables energy recovery from wastewater, based on the selective adsorption of urea from urine and its subsequent decomposition into hydrogen.
Removal of nitrogen compounds is at the core of wastewater treatment, as their uncontrolled discharge...Read more

Development and Application of a novel anaerobic/aerobic/anoxic process in municipal wastewater treatment utilizing intracellular carbon sources
Gao X., (Corresponding) Peng Y.
Topic:
Wastewater treatment
Municipal wastewater treatment plants (WWTPs) face a significant challenge in controlling treatment costs while meeting increasingly stringent wastewater discharge standards. To address this challenge, A novel anaerobic/anoxic/aerobic (AOA) process has been proposed. In this study, long-term...Read more
