Water supply organizations are currently in need of innovative solutions and technologies based on the concept of the closed-loop resource cycle. The need for sustainable use of resources serves as the basis for changing the existing approach where worn-out resources are considered wastes. Materials and methods. In this paper, we show that it is expedient to restore the sorption properties of granulated activated carbon (GAC) by its reactivation and reuse in closed-loop recycling. We also present methods to study GAC properties and technology of reactivation. Results and discussion. Based on the results of the GAC samples’ analysis, it was found that, during reactivation, the mass content of each fraction changes with a strongly pronounced decrease in the content of large granules with a size of 1.18–2.00 mm and an increase in the content of small granules with a size of 0.60–1.00 mm. Besides, the apparent density of the sorption material changes and the volume of carbon that underwent two reactivations falls below 75%. Conclusion. GAC reactivation in dual-media rapid filters allows us to optimize not only the operating and financial expenses of the company but also those natural resources that would have been spent for the production of new carbon

Off-stoichiometric boron-doped chemically complex intermetallic alloys (CCIMAs) have recently emerged as a new avenue for overcoming the low temperature brittleness of ordered superlattices. However, their behavior at high temperatures remains unexplored. In this study, a novel (Ni39.6Co29.3Cr10Al15.8Ta3.3Nb2)98.5B1.5 CCIMA was prepared and its oxidation resistance over a wide temperature range (500 °C–950 °C) was studied. The ...

Rangeland degradation is a global environmental challenge; however, intense debate persists between equilibrium (focused on the negative effects of grazing intensity) and non-equilibrium (emphasizing livestock mobility for adapting to climate variability) theories in rangeland ecology. In recent years, an integrative theory advocating the “coexistence of equilibrium and non-equilibrium” has emerged to reconcile this debate. However, ...
