WebAug 21, 2024 · Efficient and sustainable technologies for cleaning of contaminated water and sediments are in urgent demand. In this study, a new type of sediment microbial fuel cell coupled floating bed (FB-SMFC) was developed to repair eutrophic water and sediment in a cleaner way. The effect of electrode spacing on the power generation capacity and the … WebJul 6, 2010 · In our study, coupled nitrification–denitrification is less important because sufficient nitrate was available and ammonium concentrations were low. Despite the different denitrification rates, overall nitrate removal rates observed during the experiment were similar for all treatments in the light. Denitrification only accounted for ca. 6% ...

WebABSTRACT: Measurements of N losses by denitrification from saltmarsh sediments have proved difficult because of the importance of plant metabolism and tidal cycles to sediment N cycling. In vitro approaches often do not measure the dominant coupled nitrification–denitrification pathway and/or alter in situplant growth and redox conditions. WebJul 22, 2024 · Sediment water exchange. Bottom water O 2 concentrations at our sampling site remained near 100% saturation from March to April and declined from May through August (Table 1).The lowest bottom water O 2 concentration of 3.05 mg L −1 (43% saturation) was measured in August. The lowest rates of sediment oxygen demand … WebTo provide detailed insight into the coupling between ammonification, nitrification and denitrification in stationary sand ripples, we combined the diffusion equilibrium thin layer (DET) gel technique with a computational reactive transport biogeochemical model. good foosball tables
