“…CTA-ES membrane demonstrated the highest Co 2+ and Sr 2+ retention up to 99% and 97.8% respectively using the AL-FS mode. Lee et al applied FO for the treatment of medical radioactive liquid waste produced by radiation therapy using Porifera TFC membranes [59]. The FO study were carried out with the radioisotope 125I, which was adopted as a representative radioisotope.…”

“…For example, the utilization of FO process as an alternative for applications such as radioactive waste removal is an emerging area. However, most of the time, non-radioactive isotope 59 Co(II) is often used to simulate the radionuclide 60 Co(II) ion found in the real radioactive wastewater [57]. Furthermore, the radioactivity of the radionuclides present in the liquid waste probably has influence on membrane properties in long-term operation.…”

Production of potable water or reclaimed water with higher quality are in demand to address water scarcity issues as well as to meet the expectation of stringent water quality standards. Forward osmosis (FO) provides a highly promising platform for energy-efficient membrane-based separation technology. This emerging technology has been recognized as a potential and cost-competitive alternative for many conventional wastewater treatment technologies. Motivated by its advantages over existing wastewater treatment technologies, the interest of applying FO technology for wastewater treatment has increased significantly in recent years. This article focuses on the recent developments and innovations in FO for wastewater treatment. An overview of the potential of FO in various wastewater treatment application will be first presented. The contemporary strategies used in membrane designs and fabrications as well as the efforts made to address membrane fouling are comprehensively reviewed. Finally, the challenges and future outlook of FO for wastewater treatment are highlighted.

The components of liquid radiography waste may be harmful or useful, depending on the composition of the raw material. This paper aims to remove the hazardous content from liquid radiography waste, while recoving the silver nanoparticles. The microwave plasma method was adopted to achieve this purpose. First, the conventional microwave oven was modified to generate the plasma in 100mL liquid radiogrpahy waste at 500W. The plasma generation time was varied for 1, 3, 4, 7, and 10min. In the treated liquid, the total suspended solid (TSS) was analyzed through vultraviolet spectrophotmetry, the silver (Ag) was examined through atomic absorption spectrophometory, and the biological oxygen demand (BOD) and chemical oxygen demand (COD) were discussed by titration method. In addition, the recovered silver was identified by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The resultsshow that the microwave plasma method reduced the TSS by 99.36%, the Ag by 92.73%, the pH by 3.42%, the BOD by 57.13%, and the COD by 57.14%; In addition, spherical shaped silver nanoparticles were indentified at some peaks with average crystallite size ranging from 2.64nm to 65.64nm. The research findings shed important new light on the recycling of liquid radiography waste.
