Ozonation, advanced oxidation and hydrodynamic cavitation for removal of persistant pollutants

(Corresponding) Žgajnar Gotvajn A., Čehovin M.

Topic:

Advanced oxidation processes

Ozone is commonly used in advanced oxidation processes (AOPs) in combinations with hydrogen peroxide (H2O2) and UV radiation (UV). Hydrodynamic cavitation (HC) has been experimentally proven to result in effects, typical of AOPs. Combinations of AOPs with O3, H2O2 and UV, and HC (with cavitation...Read more

Mitigation of Microcystis sp. with metallic peroxide granules: matrix effect on hydrogen peroxide release kinetics and toxicity study on invertebrates

Keliri E., Christofi M., Efstathiou N., (Corresponding) Antoniou M.

Topic:

Advanced oxidation processes

An array of mitigation strategies has been applied over the years for toxic blue-green algae with the most recent one to be hydrogen peroxide (H2O2). Hydrogen peroxide has been widely used as an alternative to copper algaecides, and it is perceived as a more environmentally friendly option for...Read more

Carbon nanotubes synthesized from LDPE for application in wet peroxide oxidation of paracetamol

(Corresponding) Roman F., Marim Lopes J., Diaz de Tuesta J., Lenzi G., Tavares da Silva A., Faria J., Gomes H.

Topic:

Advanced oxidation processes

Carbon nanotubes (CNTs) were produced by chemical vapor deposition (CVD) considering low-density polyethylene (LDPE) as a carbon source and as an alternative to upcycle plastic solid waste. The CNTs were synthesized over bimetallic catalysts (Ni and Fe) supported on Al2O3 and purified with H2SO4 to...Read more

Selective denitrification of lipophilic pollutants from oily wastewater by peroxidation using Janus-structured amphiphilic carbon nanotubes as catalysts

Sanches F., Roman F., Silva A., Diaz de Tuesta J., Marin P., Machado B., Serp P., Silva A., (Corresponding) Gomes H.

Topic:

Advanced oxidation processes

Carbon nanotubes (CNTs) were tested as catalysts in the selective denitrification of 4-nitrophenol (4-NP) from oily wastewater by catalytic wet peroxide oxidation (CWPO). The CNTs were prepared by chemical vapor deposition, feeding sequentially ethylene (E) and/or acetonitrile (A) during different...Read more

Oxidation of acetaminophen by ultrasound waves and H2O2 combined technology

(Corresponding) Villota N., Lomas J., Ferreiro C., Camarero L., Lombraña J.

Topic:

Advanced oxidation processes

This study analyses 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

Applicability of Advanced Oxidation Processes for Treatment and Recovery of Washing Machine Effluent

(Corresponding) Kılıç L., Dilsizoğlu-Akyol N., Ölmez-Hancı T.

Topic:

Advanced oxidation processes

In this study, it was successfully shown that Advanced Oxidation Processes (AOPs) are a feasible method to treat laundry wastewater originating from washing machines. Wastewater characterization from different stages of wastewater discharge was analysed and advanced oxidation processes including O3...Read more
