Evaluation of Pressure-Driven Membrane Processes for Nutrients Recovery from Dilute Effluents

Tsaridou C., Karanasiou A., (Corresponding) Plakas K., Karabelas A.
Topic: 
Circular economy and industrial symbiosis
Results are presented from an ongoing R&D project, aiming at full utilization of dairy-industry effluents. Development of a membrane-based method is pursued, for treatment of digestate (after fermentation yielding bio-gas) to recover nutrients (N-NH4, P-PO4) and water for reuse/recycling or...Read more

Degradation of refractory compounds in industrial wastewaters by advanced technologies based on electrochemical and photochemical oxidation

Petsi P., Sarasidis V., (Corresponding) Plakas K., Karabelas A.
Topic: 
Advanced oxidation processes
Results are presented of a systematic experimental investigation aiming to eliminate refractory organics from industrial effluents, of high and non-biodegradable organic load, by two Advanced Oxidation Processes (AOPs). Bench scale experiments were performed with real wastewater samples collected...Read more

Development and demonstration of an eco-innovative system for sustainable treatment and reuse of municipal wastewater in small and medium size communities in the Mediterranean region

(Corresponding) Plakas K., Karabelas A., Takavakoglou V., Chatzis V., Oller-Alberola I., Polo-López I., Al-Naboulsi T., El Moll A., Kallali H., Mensi K., M'Hiri F., Simon Andreu P.
Topic: 
Sustainable water management in the mediterranean – technological solutions, demonstration and deployment
Treated municipal wastewater is considered a valuable non-conventional water resource. However, a substantial number of wastewater treatment plants installed in the Mediterranean region have proven to be unsuccessful copies of systems operating in technolo-gically advanced countries. In addition to...Read more

SWOT analysis of the institutional, policy and regulatory framework governing wastewater treatment and reuse in Tunisia, Lebanon and Spain

Kallali H., (Corresponding) Plakas P., Pana E., Karabelas A., De Ketelaere D., Spiteri A., El Moll A., Al-Naboulsi T., Mensi K., Jbeli S., M'Hiri F., Simon Andreu P., Lopez R.
Topic: 
Sustainable water management in the mediterranean – technological solutions, demonstration and deployment
This paper offers a concise overview of the main strengths, weaknesses, opportunities and threats, as derived from the institutional, policy and regulatory framework governing wastewater treatment and reuse in three Mediterranean countries. The SWOT analysis is based on a desk review of available...Read more

Investigation of variables affecting UV-LED photocatalytic degradation of antibiotics ciprofloxacin and sulfamethoxazole

(Corresponding) Bertagna Silva D., Buttiglieri G., Babić S.
Topic: 
Advanced oxidation processes
In this study, photolytic and photocatalytic degradation of two antibiotics in ultra-pure water were analyzed. A lab-scale cylindrical reactor had its inner walls impregnated with TiO2 nanofilm for the photocatalytic experiments. In the first step, an optimized photoreactor design was chosen based...Read more

Prior electro-mechanical separation to improve metal recovery from ceramic-rich electronic waste using bioleaching

(Corresponding) Baniasadi M., Ray D., Graves J., Bolton R., Renshaw D., (Corresponding) Farnaud S.
Topic: 
Solid waste management
PCBs, as one of the most valuable streams of e-waste, are a considerable source of precious metals, but also contain considerable amounts of plastic and ceramic. These non-metallic fractions interfere with and can inhibit the efficiency of metal recovery, particularly for precious and rare earth...Read more

BRIEF BIOLOGY OF Sudanonautes africanus (CRUSTACEA: BRACHYURA: EUBRACHYURA: POTAMOIDEA: PATAMONAUTIDAE: POTAMONAUTINAE), IN OSSIOMO RIVER, NIGER-DELTA, NIGERIA

(Corresponding) Anani O., John O.
Topic: 
Biodibersity conservation
The crab species africanus is a very notable detritivore, feeding on dead organic materials. It makes use of energy from the food and transfers it into the food chain trophic level, contributing to the gross ecosystem efficiency. However, their threat to human consumption and activities is...Read more

CO abatement via Ir-based catalysts: effect of the support and preparation method on catalytic activity and stability

Drosou C., Fountouli T., Stratakis A., Charisiou N., Goula M., (Corresponding) Yentekakis I.
Topic: 
Air pollution
Here we report on the effect of the support and preparation method on the activity and stability of Ir-based catalysts under CO oxidation. Alunina-ceria-zirconia (ACZ: 60wt%Al2O3 - 40wt%CexZr1-xO2, x=0.25, 0.5, 0.75) mixed oxide supports with high oxygen storage capacity (OSC) were synthesized via...Read more
