US/H2O2 combined technology applied to the paracetamol oxidation
Villota N., (Corresponding) Jose L.
Topic:
Advanced oxidation processes
This study analyzes the colour acquired by oxidizing paracetamol aqueous samples through the combined US/H2O2 technology. When operating with only the action of the waves [US]=1.0 kWh/mmol C8H9NO2, the water acquires progressively hue according to a ratio of 0.0004 AU/min, with a degradation output...Read more
Oxidation of waters containing caffeine was conducted by a sono-Fenton treatment employing an ultrasound power of 720 W at pH=3.0 and T=25°C. The catalytic action of ferrous ion was studied in a range of [Fe]=0-100.0 mg/L and oxidant concentrations between [H2O2]=0-250.0 mM. The oxidation of...Read more
Oxidation of carbamazepine by photo-Fenton treatment
Lomas J., (Corresponding) Villota N., Ferreiro C., Lombraña J.
Topic:
Advanced oxidation processes
Oxidation of waters containing 50.0 mg L-1 of carbamazepine was conducted by a photo-Fenton reagent employing a UV lamp of 150W, at pH=3.0 and T=40°C. The oxidising action of hydrogen peroxide was studied in a range between [H2O2]0=0-15.0 mM. When applying stoichiometric ratios of 2 mol C15H12N2O:...Read more
Technical optimization of a treatment process on ABE effluent by membrane technologies
(Corresponding) Stoller M., Bravi M., Russo P., Bubbico R., Mazzarotta B., Sed G., Moroni M.
Topic:
Water and wastewater reuse
In the last decades, the interest in biofuel production is sensibly growing as a good source of sustainable energy and a valid alternative to fossil ones. One of the most promising biofuel is butanol and might be produced by starting from different substrates, such as second generation ones, that...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

Life Cycle Assessment of Cheese in Terms of Climate Change
(Corresponding) Dagiliūtė R., Minkevičiūtė I., Dikšaitytė A.
Topic:
Life cycle analysis (lca)
Milk products are important sources of nutrients in the human diet; however, they have a significant impact on the environment, particularly because of the greenhouse gases that are generated during the production of these products. Therefore, this study aims to analyze the impact of life cycle of...Read more

Efficiency of Arsenic Removal from Water Using Fe-Modified Biochar from Date-Palm-Leaves Combined with Spectral Induced Polarization (SIP) Monitoring
Siddiq O., (Corresponding) Tawabini B., Kirmizakis P., Kalderis D., Ntarlagiannis D., Soupios P.
Topic:
Water treatment
In this study, lab-scale column batch adsorption experiments were conducted to demonstrate the efficiency of Iron-modified Biochar (Fe-BC) produced from date-palm leaves at 500oC to remove arsenic (As) from contaminated water. The As removal capacity were monitored by both chemical analysis and...Read more

Statistical prediction models for the odour emissions quantification in terms of odour concentration: Analysis and comparison
(Corresponding) Galang M., Ballesteros Jr. F., Zarra T., Naddeo V., Belgiorno V.
Topic:
Environmental odour, monitoring and control
Measuring odour concentration is a significant step to achieve efficient environmental odour management in continuous, objective and repeatable manner. To deal with this, researchers developed instrumental odour monitoring systems (IOMS) by applying odour monitoring models (OMM) for prediction. At...Read more
