Anaerobic ammonium nitrogen oxidation and sulphate reduction in psychrophilic conditions
Przywara L.
Topic:
Wastewater treatment
Investigations of simultaneous removal of ammonium and sulphate were carried out in anaerobic laboratory bioreactor - upflow anaerobic filter (UAF). The bioreactor was filled with the anaerobic activated sludge from WWTP Bielsko – Biała. The process was operated in psychrophilic conditions...Read more

Nitrification inhibition test of salty wastewater containing Tetrakishydroxymethyl phosphonium sulphate (THPS), formaldehyde and methanol using salt-adapted nitrifying bacteria, an alternative test method to ISO method
(Corresponding) Chhetri R., Kokkoli A., Karvelas S., Andersen H.
Topic:
Wastewater treatment
Nitrification inhibition test is a standard method to test if the chemicals or samples received by wastewater treatment plant are toxic to the nitrifying bacteria in the wastewater treatment plant. Nitrification inhibition test based on ISO method ISO9509 or modified ISO9509 method (REFLAB method)...Read more

Comparison of the continuous fermentative hydrogen production efficiency from cheese whey in suspended and attached-biomass growth systems
ALEXANDROPOULOU M., LYBERATOS G., (Corresponding) ANTONOPOULOU G.
Topic:
Wastewater treatment
In the present study, comparison of dark fermentation (DF) efficiency from cheese whey (CW) in an anaerobic UpFlow Column Reactor (AUFCR), filled with a support material for biomass attachment and a Continuous Stirred Tank reactor (CSTR), was assessed. The process efficiency and stability as well...Read more

Hydrogen and organic acids production from mesophilic and thermophilic dark fermentation of sugarcane vinasse without buffers
(Corresponding) Ribeiro J., Mota T., Oliveira V., Zaiat M.
Topic:
Wastewater treatment
The main objective of this study was to evaluate the valorization of vinasse dark fermentation (DF) through bioH2 and value-added metabolites production without buffers in two similar Upflow Anaerobic Sludge Blanket (UASB) reactors under mesophilic (U30) and thermophilic (U55) conditions. An...Read more
