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

Removal of amoxicillin from processing wastewater by ozonation and UV-aided ozonation: a kinetic and economic comparative study

Ribeiro M., Ramos B., (Corresponding) de Castro Peixoto A.
Topic: 
Advanced oxidation processes
A novel empirical and scaling up simulation study is presented for degradation and mineralization of real residue of amoxicillin (AMX) pharmaceutical formulation in wastewater. A set of UV-ozone-based experiments was used in the kinetics modeling of AMX, considering several chemical/photochemical...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
