Unbiodegradable soluble COD removal from industrial wastewater by a hybrid moving bed biofilm reactor
Carucci A., Cappai G., Camedda C., Erby G., Puggioni G., (Corresponding) Milia S., Tocco G.
Topic:
Wastewater treatment
In this study, plastics industry wastewater (PIWW) characterized by high total and soluble chemical oxygen demand (tCOD and sCOD, up to ~2200 and ~1500 mg/L, respectively) and remarkable unbiodegradable soluble COD (usCOD, 508±224 mg/L, 31±14% of tCOD) concentrations was treated at laboratory scale...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
Characterization of activated carbon prepared from Aegina pistachio shells for Hg removal
(Corresponding) Karagianni E., Chatzitheodoridis E., Papassiopi N.
Topic:
Wastewater treatment
Preparation of activated carbon from agricultural bio-products is a promising way to produce useful adsorbents for Hg removal. In this study Aegina pistachio shells were used as raw materials and the activation was carried out by impregnation with ZnCl2 and heating at 750oC under N2 atmosphere...Read more
Coal fly ash zeolites as adsorbents for effective removal of heavy metals and dyes from contaminated waters
Zgureva D., (Corresponding) Boycheva S., Behunová D., Václavíková M.
Topic:
Wastewater treatment
Recently, the purification of enormous amounts contaminated industrial, agricultural and municipal waters increases the demands of low-cost and technologically feasible techniques. The application of natural zeolites in wastewater treatment is known from many years. A feasible approach for...Read more

Magnetite nanoparticles activated coal fly ash zeolites with application in waste water remediation
(Corresponding) Boycheva S., Miteva S., Trendafilova I., Zgureva D., Václavíková M., Popova M.
Topic:
Wastewater treatment
The application of zeolites in wastewater treatment is studied long ago but still many unexploited opportunities exist. Recent investigations on natural and synthetic zeolites in water decontamination are focused on the improvement of their adsorption and ion-exchange properties modifying them by...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
Fouling-resistant membranes prepared via fully biobased layer-by-layer self-assembly
Shamaei L., Ayranci C., (Corresponding) Sadrzadeh M., Khorshidi B.
Topic:
Wastewater treatment
A fully biobased layer-by-layer deposition method, containing kraft lignin and chitosan as the polyelectrolytes, was employed to improve the anti-fouling properties of polyethersulfone membrane. Results revealed that the water in air contact angle decreased from 70° ± 2° for the pristine membrane...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
