  • The characteristics of immobilized granular sludge in the laboratory-scale stable partial nitrification-Anammox aquaculture water reactors

    Immobilized granular sludge is of key importance for highly effective operation of partial nitrification and anaerobic ammonium oxidation (PN-Anammox) reactors. An observation and analysis on the composition of immobilized granular sludge in each reactor was conducted by using scanning electron microscopy (SEM) and fluorescence in situ hybridization. It was indicated that the diversity of ...

  • A new reactor for denitrification and micro-particle removal in recirculated aquaculture systems

    A ‘membrane-denitrification’ reactor (MDR) was developed and tested in a semi-technical recirculation aquaculture system in comparison to a double – without MDR – as reference system. The MDR consisted of a reactor with an ultrafiltration membrane unit for removal of micro-particles (e.g. sludge flocs, bacteria and parasites). Specific carrier material provided surfaces for biofilm growth in a ...

  • Monitoring greenhouse gases from biofuel crops

    Global issues such as climate change and energy security have driven rapid growth in renewable energy production - wind, solar, tidal, geothermal, hydro, biofuels etc. However, logically, each of these methods should deliver a net benefit in terms of greenhouse gas (GHG) reduction, so researchers in the United States have employed portable FTIR analysers to study the GHG emissions of biomass ...
