Electrochemical Treatment of Landfill Leachate under Cold Climate Conditions
(Corresponding) Ambauen N., Meyn T., Hallé C., Muff J.
Topic:
Advanced oxidation processes
This study shows that electrochemical oxidation of landfill leachate (LL) is significantly affected by cold temperatures prevailing in Nordic climate areas. As hypothesized, the degradation of common wastewater parameters (TOC, COD) exhibited lower efficiency when low average temperature (13°C) was...Read more

Combined use of anaerobic and aerobic moving bed biofilm reactors for micropollutants’ removal from wastewater
Kora E., Theodorelou D., Herpich A., Gatidou G., Fountoulakis M., (Corresponding) Stasinakis A.
Topic:
Emerging pollutants
A novel laboratory-scale continuous flow wastewater treatment system, consisting of an anaerobic moving bed biofilm reactor (AnMBBR) and an aerobic MBBR, was used for investigating the removal of hydroxybenzothiazole (OH-BTH) and selected benzotriazoles from municipal wastewater. The system was...Read more
Use of the microalgae Chlorella Sorokiniana for municipal wastewater treatment: batch experiments
Kotoula D., Iliopoulou A., Irakleous-Palaiologou E., Gatidou G., Aloupi M., Fountoulakis M., (Corresponding) Stasinakis A.
Topic:
Wastewater treatment
Batch experiments were conducted in order to investigate the use of microalgae Chlorella sorokiniana for the treatment of different types of municipal wastewater (raw sewage, anaerobically treated wastewater, aerobically treated wastewater) and investigate the role of light and addition of ammonium...Read more
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
Pharmaceutical residues in hospital and urban wastewaters: Occurrence, removal and potential risk assessment
Martinaiou P., Trantopoulos E., (Corresponding) Kosma C., Albanis T.
Topic:
Emerging pollutants
The presence of ten pharmaceutical compounds (bupropion, venlafaxine, mirtazapine, sertraline, citalopram, caffeine, triclosan, carbamazepine, diazepam, clozapine) which belong to different treatment categories was studied in one hospital and three urban WWTPs in north and northwestern Greece. The...Read more
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

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

Topic:
Water treatment
Contamination of water resources with Arsenic poses serious health concerns because of its toxic and carcinogenic nature. Detection of Arsenic at concentrations higher than 10 parts per billion (ppb) in some Philippine water resources confirmed the need for further studies on the contamination and...Read more

Novel Polyethersulfone (PES) Alpha-Zirconium Phosphate (α-ZrP) Ion Exchange Mixed Matrix Membranes for Effective Removal of Heavy Metals from Wastewater
ABDULKARIM E., IBRAHIM Y., (Corresponding) HASAN S., NADDEO V., BANAT F.
Topic:
Wastewater treatment
In this study, novel polyethersulfone (PES) alpha-zirconium (α-ZrP) ion exchange mixed matrix membranes were fabricated via phase inversion method using nano-sized alpha-zirconium phosphate (α-ZrP-n) and polyvinylpyrrolidone (PVP) as dispersant nano-additives in the dope solution preparation. The...Read more
