ORGANIC SOLID WASTE MECHANICAL PRETREATMENT FOR THE OPTIMIZATION OF ANAEROBIC DIGESTION PROCESSES
(Corresponding) Cesaro A., Cieri V., Belgiorno V.
Topic:
Biowaste
Anaerobic digestion has been recognized as the most demanding process for the valorization of organic solid waste towards the production of several, valuable intermediates (Dahiya et al., 2018), which can be further converted to a methane rich-gas to meet the current needs for renewable energy...Read more
Comparative analysis of chlorinated intermediates formed during electrochemical and photo(electro)catalytic degradation of 4-Ethylphenol in saline media
(Corresponding) Brüninghoff R., van Duijne A., Braakhuis L., Saha P., Jeremiasse A., Mei B., (Corresponding) Mul G.
Topic:
Advanced oxidation processes
Formation of toxic by-products, such as chlorinated intermediates, is one of the major drawbacks of advanced oxidation processes for saline wastewater treatment. Here a comparative analysis of electrochemical oxidation and photocatalytic degradation of 4-Ethylphenol, a non-chlorinated starting...Read more
Production of PHAs with enhanced properties from sugar-based wastewater in a two stage process
FOUSKAKIS G., STERGIOPOULOU E., ALEXANDROPOULOU M., (Corresponding) ANTONOPOULOU G., NTAIKOU I., LYBERATOS G.
Topic:
Environmental biotechnology and bioenergy
The experimental design of the study was based on two different microbial processes, i.e. anaerobic fermentation of a sugar-based wastewater via mixed acidogenic cultures and aerobic polymerization of the produced acids and alcohols for poly-hydroxy-alkanoates (PHAs) production, via enriched...Read more
Keywords:
PHAs, up-flow column reactor, SBR, two stage process
RECOVERY AND SEPARATION OF VALUABLE METALS (COPPER AND ZINC) FROM ACIDIC MINE WATERS BY ION-EXCHANGE RESINS
(Corresponding) Vecino X., Reig M., López J., Valderrama C., Gibert O., Cortina J.
Topic:
Water and wastewater reuse
Mining wastewaters, containing heavy metals such as copper (Cu) and zinc (Zn), have a huge impact on the environment due to they are not biodegradable and tend to bioaccumulate in plants or living organisms. Therefore, in this work the performance of ion-exchange and solvent-impregnated resins were...Read more

Aerobic degradation of tetramethyl ammonium hydroxide (TMAH) from effluents of semiconductor industries: kinetic studies of laboratory and pilot experiments
(Corresponding) Innocenzi V., De Michelis I., Ippolito N., Mazziotti Di Celso G., Prisciandaro M., Vegliò F.
Topic:
Wastewater treatment
Aerobic degradation of effluents contains tetramethylammonium hydroxide molecules (TMAH), coming from an electronic industry, were studied at laboratory and pilot scale. At the first, the preliminary experiments were conducted using a lab scale reactor inoculated with activated sludge coming from...Read more
Keywords:

A simple and flexible flowsheet process for recycling efficiently and selectively metals from spent fluid cracking catalysts
(Corresponding) Soares H., (Corresponding) Sadeghi M., (Corresponding) Jesus J., (Corresponding) Pinto E., (Corresponding) Almeida A.
Topic:
Solid waste management
Fluid cracking catalysts (FCCs) are used in the oil industry to crack large molecules into smaller hydrocarbons of interest, such as gasoline and other products. Considering the large volume of FCCs waste generated on a yearly basis (about 20 thousand tons of spent FCCs worldwide) as well as its...Read more
Keywords:
Fluid cracking catalysts, simple and nearly-closed process, recovery of La, recovery of Al
Degradation of Cylindrospermopsin using Advanced Non-Thermal Plasma Technologies
(Corresponding) Schneider M., Rataj R., Kolb J., Bláha L.
Topic:
Advanced oxidation processes
The application of non-thermal plasmas in wastewater and air purification received a lot of attention, but their potential application in drinking water treatment has scarcely been investigated. Classified as Advanced Oxidation Processes, plasmas ignited in water or at the air-water interface...Read more
Fluoride-free Anodization of Titanium and the Photocatalytic Behaviour the Produced TiO2 Nanostructures
Taylor C., (Corresponding) Wenk J., Mattia D.
Topic:
Advanced oxidation processes
Current methods for anodizing titania to produce immobilized titanium dioxide (TiO2) photocatalyst require the use of hazardous fluoride electrolytes. A fluoride-free electrolyte anodization method was developed. The electrolytes tested in this study were both bromide- and chloride-based and...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

Valorisation of ovine cheese whey through PHA production
(Corresponding) Asunis F., Brundu A., Carucci A., Cocco F., De Gioannis G., Isipato M., Muntoni A., Spiga D.
Topic:
Biowaste
The ovine dairy supply chain plays an important role in Mediterranean economic systems and is experiencing a much needed phase of development and innovation looking beyond traditional dairy products. The same attention to innovation has not yet been applied to the management of the effluents...Read more
