New pillared clays for the removal of pollutants from wastewater by treatment with oxidation processes

(Corresponding) Kalmakhanova M., Massalimova B., Diaz de Tuesta J., Gomes H.

Topic:

Advanced oxidation processes

The constant development of technological processes aggravates the problem of pollution, due to a significant change in the composition of effluents that makes necessary the development of new (and/or improvement of the existing) treatment methods and catalytic materials. In this sense, the use of...Read more

Application of carbon-based catalysts derived from compost on catalytic wet peroxide oxidation of leachate waters from mechanical and biological treatment plant units for municipal solid waste

Batista G., (Corresponding) Roman F., Diaz de Tuesta J., Mambrini R., Gomes H.

Topic:

Advanced oxidation processes

This work aims at the valorization of compost from mechanical and biological treatment (MBT) units of municipal solid waste by their transformation into carbon-based catalysts for further application in the treatment of MBT leachate waters (chemical oxygen demand (COD) = 60.0 g L-1, total organic...Read more

Preliminary Research on Removal of Organic Substances Contained in Wastewater from Plastic Lenses Production

(Corresponding) Umiejewska K., Różycki M.

Topic:

Advanced oxidation processes

More than 80 percent of all eyeglasses worn today have plastic lenses. Plastic lenses made of polycarbonate discs are created through the process of machining which requires the use of a coolant. During the production process, the rotating disc and blade are poured with a mixture of water and...Read more

SELECTED APPLICATIONS of CAVITATION BASED ADVANCED OXIDATION PROCESSES (AOPs) for TREATMENT of WATER and INDUSTRIAL EFFUENTS

Fedorov K., Cako E., (Corresponding) Boczkaj G.

Topic:

Advanced oxidation processes

Cavitation phenomenon was effectively applied for enhancement of Advanced Oxidation Processes (AOPs) effectiveness. Main applications are focused on treatment of water as well as industrial effluents [1-2]. Cavitation phenomenon can be generated in the liquid by intentionally formed differences in...Read more

Degradation of cytostatic drugs in water by ozonation

(Corresponding) Garcia-Costa A., Gouveia T., Pereira M., Silva A., Alves A., Madeira L., Santos M.

Topic:

Advanced oxidation processes

This work presents the degradation of five cytostatics found in Portuguese WWTP effluents: bicalutamide (BICA), capecitabine (CAP), cyclophosphamide (CYC), ifosfamide (IFO) and mycophenolic acid (MPA) using non-catalytic ozonation. Experiments were performed with 1 µM of each cytostatic at pH: 7.3...Read more

Ηexavalent chromium reduction in a photocatalytic membrane reactor in the presence of organic acids

(Corresponding) Sarasidis V., Kyriakou E., Plakas K., Karabelas A.

Topic:

Advanced oxidation processes

This study deals with the photocatalytic reduction of carcinogenic hexavalent chromium, encountered in industrial effluents and surface waters, to much less toxic and harmful trivalent form. Experiments were performed in a pilot scale Photocatalytic Membrane Reactor employing titanium dioxide...Read more

Application of solar photo-Fenton oxidation coupled with granular activated carbon as a viable option for the removal of contaminants of emerging concern in the urban wastewater of India

Karaolia P., Korelidou A., (Corresponding) Fatta-Kassinos D.

Topic:

Advanced oxidation processes

It has been estimated that approximately 62 billion litres of sewage are generated every day in India, with only 37% of sewage being treated (Saxena et al., 2021). Wastewater treatment issues such as dysfunctional UWTPs with many of them operating at low service levels compared to the design...Read more

On the Fenton oxidation of polystyrene microplastics

(Corresponding) Munoz M., Ortiz D., Nieto-Sandoval J., Romera-Castillo C., de Pedro Z., Casas J.

Topic:

Microplastics in water treatment: fate, toxicity assessment and removal technologies

This work aims at evaluating the fate of polystyrene (PS) microplastics along Fenton oxidation. Experiments were carried out under relatively severe operating conditions (80 ºC) given the high persistence of these solids to oxidation. Slight mass losses (up to 10%) were found after the Fenton...Read more

Nanoplastics mineralization by the intensified photo-Fenton process

(Corresponding) Ortiz D., Munoz M., Carbajo J., M. de Pedro Z., Casas J.

Topic:

Microplastics in water treatment: fate, toxicity assessment and removal technologies

The widespread presence of microplastics (MPs) and nanoplastics (NPs) in aquatic systems has become one of the most challenging environmental issues nowadays. Although advanced oxidation processes (AOPs) have been widely studied for the treatment of persistent contaminants in water, their...Read more
