Global attention is increasingly focused on the challenges of environmental damage and the depletion of natural resources. Factors such as population growth, rising living standards, rapid urbanisation, and intensified industrial activities have collectively contributed to a significant increase in water pollution.
Radiation technologies have emerged as powerful tools in industry,...
Per-and polyfluoroalkyl substances (PFAS) are a broad group of specialty chemicals used in applications such as food packaging, personnel care products and stain resistant fabrics. PFAS are both thermally and chemically stable due to strong dipole moments in C-F bonds created by the highly electronegative fluorine atom. Some uses of PFAS, one of the most noted being aqueous film forming foam...
The Electron Beam Research Facility, where most of the studies reported today were conducted, is located at the Miami-Dade Virginia Key Wastewater Treatment Plant, Miami, Florida. It was a High Voltage Engineering, 1.5 MeV Insulated Core Transformer (ICT), 50 mA horizontal-beam accelerator. Originally designed to treat wastewater biosolids (sludge) prior to land application, it had two...
The high temperatures and reactive radicals generated during irradiation by electron beam can degrade or remove challenging contaminants such as petroleum hydrocarbons and per- and polyfluoroalkyl substances (PFAS). Reductions in hydrocarbon concentrations of up to 98.4% were observed for field soils using a 10 MeV, 18 kW accelerator; hydrocarbons of all weights were reduced, suggesting both...
The polymeric materials are extensively being employed for the various applications such as health care, storage, packaging materials for the foods, beverages, and saline etc. The most commonly used polymer in these applications are polyethylene terephthalate (PET) silicone rubber, polyurethane, due to their flexibility, low cost, biocompatible nature and other properties. However, these...
