Challenges in biological treatment plants: the approach of zero sludge waste
THEOFANIDIS S., Samiotis G., Bellos D., Pekridis G., Tsioptsias C., (Corresponding) Amanatidou E.
Topic:
Wastewater treatment
The current trend in operation of biological Wastewater Treatment Plants (WWTPs) is the minimization of sludge wastage due to its labor and cost intensive management process. Minimization of sludge can be achieved by increasing the solids retention time (SRT) in a WWTP, up to an almost complete...Read more
Elimination of relevant pharmaceuticals in hospital wastewater from Colombia by combination of a biological system with a sonochemical process
(Corresponding) TORRES PALMA R., Serna-Galvis E., Silva-Agredo J.
Topic:
Advanced oxidation processes
This work presents the treatment of selected emerging concern pharmaceuticals in real hospital wastewater (HWW) from Tumaco-Colombia by combination of a biological system with a sonochemical process. Fifteen compounds, commonly present in HWW, were considered: acetaminophen, diclofenac,...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
