Influence of microbial fuel cell integration on organic matter and nutrient removal in a constructed wetland for wastewater treatment
(Corresponding) Gonzalez T., Miranda J., Vidal G.
Topic:
Wastewater treatment
The combination of constructed wetlands (CWs) and microbial fuel cells (MFCs) has emerged in recent years with the purpose of enhancing wastewater treatment efficiency of CWs while simultaneously generating electricity. Taking the above into account, the aim of this study is to evaluate the...Read more
Cavitation based Advanced Oxidation Processes for Wastewater Treatment – comparison of hydrodynamic and sonocavitation systems
(Corresponding) Boczkaj G., Gągol M., Fedorov K., Cako E.
Topic:
Advanced oxidation processes
Cavitation based advanced oxidation processes (AOPs), are a promising alternative to currently used wastewater treatment technologies [1-2]. Amplified interest in this “hot” topic results in increased number of research on several aspects relating to formation of cavitation phenomena and its...Read more
Cobalt and Phosphorous Recovery from Semiconductor Wastewater through Homogeneous Crystallization of Cobalt Phosphate in a Fluidized-bed Reactor
Bayon L., Ballesteros Jr. F., Segura-Garcia S., (Corresponding) Lu M.
Topic:
Heavy metals in the environment
Semiconductor manufacturing involves distinct processes that generate complex wastewater streams that require treatment before it proceeds to the main wastewater effluents. The present study utilized fluidized-bed crystallization to recover resources from the combined synthetic wastewater of...Read more
UN(K)NOWN Project: Development of Anammox microbial inocula to improve nitrogen removal efficiency in wastewater treatment
(Corresponding) Ribeiro H., Machado A., Costa-Dias S., Wijaya I., Salgado P., Bordalo A., Teixeira C.
Topic:
Wastewater treatment
The discovery of anaerobic ammonium oxidation (anammox) revealed the existence of a shortcut in the classic nitrogen cycle where ammonium is converted directly to dinitrogen gas. Anammox process can be used to develop more cost and energy-efficient sustainable nitrogen removal systems comparing to...Read more
Start-up of the nitrogen removal process in an anaerobic up-flow reactor inoculated with aeration tank sludge
Wijaya I., (Corresponding) Ribeiro H., Soedjono E., Slamet ., Teixeira C., Bordalo A.
Topic:
Wastewater treatment
Anaerobic ammonium oxidation (anammox) has been considered a promisingly alternative to traditional nitrification/denitrification to remove nitrogen in an autotrophic process, without using an external carbon source, requiring low energy consumption and sludge production. The start-up of the...Read more
3D printed lab-scale raceway ponds reactors for photo-Fenton processes
Nasr Esfahani K., Zandi M., Travieso-Rodriguez J., Graells M., (Corresponding) Perez-Moya M.
Topic:
Advanced oxidation processes
Abstract
Raceway pond reactors (RPRs) have been widely used in microalgae mass culture (Acien et al., 2013) and their application for micro pollutant removal in photo-Fenton processes has been recently assessed (Rivas et al., 2015). The main advantages of raceway pond reactors are being low cost...Read more

Hybrid zero liquid discharge (ZLD) membrane/chemical process for the treatment of oil sands produced water
Mohammadtabar F., (Corresponding) Khorshidi B., Hayatbakhsh A., (Corresponding) Sadrzadeh M.
Topic:
Wastewater treatment
In this study, the applicability of a hybrid chemical/membrane process for the treatment of the boiler blow-down (BBD) water from steam assisted gravity drainage (SAGD) operation was explored. For the chemical pre-treatment prior to the membrane filtration, another waste stream of SAGD, i.e., ion...Read more

Wastewater treatment; Membrane filtration; Boiler blowdown; Nanofiltration; Process integration
Karkooti A., Rastgar M., (Corresponding) Sadrzadeh M.
Topic:
Water treatment
As an obstacle against the widespread application of membranes in larger scales, fouling via different materials could cause a severe decline in water permeation. Herein, we fabricated a novel mechanically-stable electro-conductive membrane by simple pressure-assisted laminating of reduced Graphene...Read more
TREATMENT OF SLAUGHTER HOUSE WASTEWATER UTILIZING COGON GRASS (Imperata cylindrica) IN A SUBSURFACE FLOW SYSTEM CONSTRUCTED WETLAND IN ZAMBOANGA CITY, PHILIPPINES
(Corresponding) Flores R., (Corresponding) Adil J.
Topic:
Wastewater treatment
Natural treatment systems are gaining a preference for wastewater treatment as an ecosystem-based adaptation to climate change. This study investigated the performance of a laboratory scale horizontal subsurface flow constructed wetland (SSFCW) planted with cogon grass (Imperata cylindrica) in...Read more
A nine-year study on the temporal changes of licit and illicit drug use patterns as revealed from the chemical analysis of influent wastewater from the wastewater treatment plant of Athens
Galani K., Alygizakis N., Borova V., (Corresponding) Thomaidis N.
Topic:
Emerging pollutants
Daily flow-proportional composite influent wastewater was collected from the Wastewater Treatment Plant (WWTP) in Athens during a nine-year sampling campaign (2010-2019). Analytes in influent wastewater are markers of the consumption and the exposure of the chemicals in the population. Wastewater...Read more
