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
Pretreatment of antibiotics-contaminated waste biological sludge by ozonation
Boševski I., (Corresponding) Kalčikova G., Derco J., Žgajnar Gotvajn A.
Topic:
Wastewater treatment
Ozonation was studied as a pretreatment method for a waste biological sludge, contaminated with large amounts of globally used antibiotics; tiamulin, levofloxacin and amoxicillin. At the concentrations of over 100 mg L-1, these antibiotics were found to inhibit biogas production (up to 50%), which...Read more
Tuning of an advanced control system on a membrane process for tannery wastewater purification and chromium recovery purposes
Marchetti A., (Corresponding) Stoller M.
Topic:
Wastewater treatment
Tannery wastewater represent a hazard to the environment due to its high content of chromium. Conventional methods to purify this wastewater stream are available, but not capable to recover back chromium to the tannery process. Membranes appears to be a promising technology to achieve both targets...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
Feasibility of combined anaerobic-aerobic system for textile wastewater contained C. I. Acid Red 88 dye treatment: HRT effects and functional resilience
(Corresponding) Gadow S., Li Y.
Topic:
Wastewater treatment
An integrated continuous anaerobic–aerobic system has been employed as the treatment for synthetic textile wastewater contained C. I. Acid Red 88 dye. A laboratory scale of upflow anaerobic sludge bed (UASB) flowed by activated treatment was operated at hydraulic residence time (HRT) of 24, 12, 6,...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
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

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

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
