Protein rich wastes from aquaculture systems result in total ammonia nitrogen (TAN), total
organic carbon (TOC) and biochemical oxygen demand (BOD). A number of conventional …

Several approaches of hydrogenotrophic denitrification of potable water as well as technical
data and mathematical models that were developed for the process are reviewed. Most of …

All organisms require an electron donor and acceptor, frequently in chemical form, but an
elegant alternative is to supply these via direct electrochemical means. Electricity has been …

An intensified biofilm–electrode reactor (IBER) combining heterotrophic and autotrophic
denitrification was developed for treatment of nitrate contaminated groundwater. The reactor …

Combined bioelectrochemical and sulfur autotrophic denitrification (CBSAD) system had
proven to be feasible for nitrate removal at low temperature. This system obtained excellent …

The contamination of nitrate in groundwater has become an ever-increasing environmental
problem. To improve denitrification rate effectively, a novel three-dimensional (3D) bio …

The low denitrification effect on constructed wetlands (CWs) treating low carbon to nitrogen
ratio (C/N) wastewater was a problem. In this study, a novel coupled system by installing CW …

In this study, a multi-cathode biofilm-electrode reactor (BER) combined with microfiltration
(MF) was investigated using a laboratory-scale experimental apparatus for treatment of …

The main factor that determines the success of a bio-electrochemical system (BES) is the bio-
electrode. This paper reviews the direct as well as mediated electron transfer mechanisms in …

The long-term performance of the biofilm-electrode reactor is demonstrated for
denitrification. The total nitrate and nitrite concentration, oxidation-reduction potential (ORP) …
