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

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

Destruction of Perfluorooctanoic acid (PFOA) in water by cold atmospheric plasma

Papalexopoulou K., Ronen A., (Corresponding) Aggelopoulos C.

Topic:

Advanced oxidation processes

Cold atmospheric plasma was investigated as for the remediation of perfluorooctanoic acid (PFOA) contaminated water. The destruction of the highly toxic PFOA is a challenging task since it is a persistent and bioaccumulative chemical causing pollution in waterbodies. In this study, plasma...Read more
