Side-Stream Phosphorus Recovery in Activated Sludge Processes
Authors: Daneshgar Saba , Cecconet Daniele , Capsoni Doretta , Capodaglio Andrea G.
Published: June 2022

Precipitation of mineral phosphates from wastewater treatment processes is an excellent method for phosphorus recovery, leading to the formation of compounds with high fertilizing value. Conventionally, P-precipitation processes are mostly applied to supernatant of anaerobic sludge digestates, due to their high P and N residual contents. This study concerns P-recovery in a pilot-scale side-stream reactor from aerobic (activated sludge) wastewater liquor. The effect of process retention time and pH was determined using sodium hydroxide and calcium hydroxide as alternative pH buffer reagents, in both synthetic and real wastewater. Equilibrium mass balance calculations were first applied to estimate the theoretical final composition of P-precipitates under different process conditions; then, actual precipitation experiments were carried out with synthetic wastewater to define optimal process operating parameters in controlled conditions. Results showed that phosphorus precipitation was affected mainly by solution pH and did not significantly depend on the reactor’s retention time. These findings were validated by operating the process with real wastewater: on average, 61.2% and 90.4% phosphorus precipitation (recovery) were achieved at pH = 8.5 and 9.0 under a controlled Mg:NH4:P molar ratio of 5:5:1, using sodium hydroxide as acidity buffer. The main fraction of final precipitates consisted of calcium phosphate compounds, while struvite, bobierrite and calcite showed up in smaller proportions. It was also shown that dosage of calcium hydroxide for pH adjustment, without any other chemicals for molar ratios adjustment of the solution, has great potential for P recovery in the form of a calcium phosphate-rich precipitate, usable for fertilizer, with 75.6% phosphorus removal in mineral form at pH = 8.5. The process is much less costly to operate than struvite precipitation, and more energetically sustainable. This scheme could be ideally suited for application in facilities operating under an enhanced phosphorus removal process scheme.

Published: June 2022

The reliability of weather radar data in real-time flood forecasting and early warning system remain ambivalent due to high uncertainty in Quantitative Precipitation Forecasts (QPF). In this study, a methodology is presented with the objective to improve the flood forecasting results with the application of radar rainfall calculated in three different ways. The QPF radar rainfall forecast data of four typhoon events in Fèngshān River Basin, Taiwan, were simulated using the WASH123D numerical model. The simulated results were corrected using a physical real-time correction technique and compared with direct simulation without correction for all three QPF calculation methods. According to model performance evaluation criteria, in the third method of QPF calculation, flood peak error was the lowest in all three methods, indicating better results for flood forecasting and can be used for flood early warning systems. The impact of the real-time correction technique was assessed using mass balance analysis. It was found that flow change is between 16% and 42% from direct simulation, indicating being on the safe side in case of a flood warning. However, the impact of the real-time physical correction on the water level itself is in a reasonable range. Still, QPF rainfall correction/calculation is more important to obtain accurate results for flood forecasting. Therefore, the application of real-time correction to correct the model water level has a certain degree of credibility, which is the mass balance of the model. This approach is recommended for flood forecasting early warning systems.
Whole-Plant Water Use and Hydraulics of Populus euphratica and Tamarix ramosissima Seedlings in Adaption to Groundwater Variation
Authors: Li Jun , Hu Shunjun , Sheng Yu , He Xiran
Published: June 2022

Riparian phreatophytes in hyperarid areas face selection pressure from limiting groundwater availability and high transpiration demand. We examined whole-plant water use and hydraulic traits in Populus euphratica and Tamarix ramosissima seedlings to understand how they adapt to groundwater variations. These species coexist in the Tarim River floodplain of western China. Measurements were performed on 3-year-old seedlings grown in lysimeters simulating various groundwater depths. P. euphratica had relatively greater leaf area-specific water use due to its comparatively higher sapwood area to leaf area ratio (Hv). A high Hv indicates that its sapwood has a limited capacity to support its leaf area. P. euphratica also showed significantly higher leaf-specific conductivity (ksl) than T. ramosissima but both had similar sapwood-specific conductivities (kss). Therefore, it was Hv rather than kss which accounted for the interspecific difference in ksl. When groundwater was not directly available, ksl and Hv in P. euphratica were increased. This response favors water loss control, but limits plant growth. In contrast, T. ramosissima is more capable of using deep groundwater. Stomatal sensitivity to increasing leaf-to-area vapor pressure deficit was also higher in P. euphratica. Overall, P. euphratica is less effective than T. ramosissima at compensating for transpirational water loss at a whole-plant level. For this reason, P. euphratica is restricted to riverbanks, whereas T. ramosissima occurs over a wide range of groundwater depths.
Water Reservoirs as a Driver of Anthropogenic Changes in Landscape and Transport Networks: The Czech Republic Experience
Authors: Havlíček Marek , Dostál Ivo , Pavelková Renata
Published: June 2022

The construction of reservoirs has a major impact on the floodplain landscape, and their existence also affects land use in the hinterland. The aim of this article is to evaluate the influence of artificial lakes on changes in landscape use and transport networks; in this context, an assessment is provided of the significance of this anthropogenic activity as one of the drivers of landscape change. Old topographic maps and archival aerial photographs are used to analyze changes in the use of landscape and road networks, and these materials are complemented with the latest geographic data in digital form. Utilizing geographic information systems, we assessed the landscape changes and processes in the hinterland of those Czech Republic reservoirs that have an area of 100 ha or more. The results of the research show that landscape change processes are more intensive in the hinterland of the lakes than in the surrounding landscape. The predominant utility function of a reservoir emerged as a key factor in landscape use changes and ongoing processes. A different landscape use scenario can be observed in drinking water reservoirs, especially regarding the leisure and irrigation functions that dominate elsewhere. After the completion of reservoirs, the road and railway networks had an impact on, above all, the connection of the nearest villages in the hinterland of the lakes. The information that we found can be employed in projecting future changes in land use and road networks at newly planned dams.

Published: June 2022

Xiong’an New Area, located in the middle of the North China Plain, will have been built as a “city of the future.” Urban planning and construction need to comprehensively consider the constraints of hydrogeological conditions such as aquifer structure and parameters. As the main aquifer in this area, the paleo-channel is heterogeneous and anisotropic, and the two-dimensional hydraulic conductivity in each horizontal direction cannot be obtained from aquifer tests. Therefore, this study adopts a chemical kinetics method to calculate the ionic activity and mineral saturation indices of shallow groundwater, determine the groundwater chemical potential field, and construct a horizontal two-dimensional groundwater chemical kinetics model. This model is used to calculate the hydraulic conductivity, flow rate and retention time of groundwater in areas of different chemical kinetics, as well as evaluate horizontal heterogeneity of the Quaternary paleo-channel aquifer. The results indicate that the groundwater chemical potential field can reflect the characteristics of the groundwater seepage field in each horizontal direction. The paleo-channel is the main channel of groundwater circulation, which shows the statistical difference of its permeability. Alluvial and lacustrine strata affect groundwater circulation due to their different hydrogeological structures and permeability. The groundwater chemical kinetics results of hydraulic conductivity along the paleo-channel are approximately consistent with traditional hydrogeological calculation results derived from aquifer test data. Hydraulic conductivity is higher in the extension direction of the paleo-channel, and lower if the path crosscuts multiple paleo-channels. This feature can be used to build a hydrogeological structure model combined with drilling data. Furthermore, excessive groundwater exploitation will change the actual flow rate and retention time of groundwater, thereby affecting the groundwater circulation conditions. This study of groundwater circulation in Xiong’an New Area by means of chemical kinetics makes up for the deficiency in the study of the unconsolidated sedimentary aquifer anisotropy within the paleo-channel.
Comparison of Projections of Precipitation over Yangtze River Basin of China by Different Climate Models
Authors: Pan Hong , Jin Youjie , Zhu Xiaochen
Published: June 2022

Based on the observational dataset CN05.1 and the Coupled Model Intercomparison Project (CMIP), this study assesses the performance of CMIP5 and CMIP6 projects in projecting mean precipitation at annual and seasonal timescales in the Yangtze River Basin of China over the period 2015–2020 under medium emission scenarios (RCP4.5/SSP2-4.5). Results indicate that the multi-model ensemble (MME) of CMIP6 overall has lower relative bias and root-mean square error of both annual and seasonal mean than that of CMIP5, except for winter, but both of the two ensembles show the best projected accuracy in winter. Generally, CMIP6 outperformed CMIP5 in capturing spatial and temporal pattern over the YRB, especially in the midstream and downstream areas, which have high precipitation. Further analyses suggest that the CMIP6 GCMs have lower median normalized root-mean square error than CMIP5 GCMs. Based on the Taylor skill (TS) score, both CMIP6 and CMIP5 GCMs are ranked to evaluate relative model performance. CMIP6 GCMs have higher ranks than CMIP5 GCMs, with an average TS score of 0.68 (0.55) for CMIP6 (CMIP5), and three out of the five highest scored GCMs are CMIP6 GCMs. However, the CMIP6 precipitation projections are still quite uncertain, thus requiring further assessment and correction.

Published: June 2022

The many hydrodynamic implications associated with the geomorphological evolution of braided rivers are still not profoundly examined in both experimental and numerical analyses, due to the generation of three-dimensional turbulence structures around sediment bars. In this experimental research, the 3D velocity fields were measured through an acoustic Doppler velocimeter during flume-scale laboratory experimental runs over an emerging sand bar model, to reproduce the hydrodynamic conditions of real braided rivers, and the 3D Turbulent Kinetic Energy (TKE) components were analyzed and discussed here in detail. Given the three-dimensionality of the examined water flow in the proximity of the experimental bar, the statistical analysis of the octagonal bursting events was applied to analyze and discuss the different flume-scale 3D turbulence structures. The main novelty of this study is the proposal of the 3D Hole Size (3DHS) analysis, used for separating the extreme events observed in the experimental runs from the low-intensity events.
Laboratory-Scale Study on the Effects of Freezing in Soils when Subjected to Different Moisture Content
Authors: Pennisi Svoboda V. , Habteselassie Mussie Y.
Published: June 2022

This study was undertaken to investigate how soil characteristics and moisture content impact the freezing process in soils that are common in Georgia, United States. Three soil types (sand, loam, clay loam) with a water content of 30% or 40% field capacity were subjected to temperatures of −1.0 °C, −1.5 °C and −2.0 °C, respectively, in a freezing chamber. The three soil types revealed unique freezing profiles at both 30% and 40% field capacity. In general, all soil types at 40% field capacity remained at higher temperatures for longer periods of time compared to the same soil type at 30% field capacity. The loam soil at 40% WHC (water holding capacity) took the longest time to reach all four threshold temperatures. Both the soil texture and amount of water available for freezing affected the time each soil and water combination took to reach the threshold temperatures. These results have practical implications for the ornamental landscape industry and gardeners in subtropical climates where annual flowers are commonly grown in winter color beds. Since subfreezing soil temperatures are not as common in subtropical areas as they are in more northern climates, especially in recent decades, it would be worthwhile to examine the impact of additional factors such as organic content and nutrition on freezing processes in subtropical soils.

Published: June 2022

The Yellow River Basin is an important economic belt and key ecological reservation area in China. In the context of global warming, it is of great significance to project the drought disaster risk for ensuring water security and improving water resources management measures in practice. Based on the five Global Climate Models (GCMs) projections under three scenarios of the Shared Socioeconomic Pathways (SSP) (SSP126, SSP245, SSP585) released in the Sixth Coupled Model Intercomparison Project (CMIP6), this study analyzed the characteristics of meteorological drought in the Yellow River Basin in combination with SPEI indicators over 2015–2100. The result indicated that: (1) The GCMs from CMIP6 after bias correction performed better in reproducing the spatial and temporal variation of precipitation. The precipitation in the Yellow River Basin may exhibit increase trends from 2015 to 2100, especially under the SSP585 scenario. (2) The characteristics of meteorological drought in the Yellow River Basin varied from different combination scenarios. Under the SSP126 scenario, the meteorological drought will gradually intensify from 2040 to 2099, while the drought intensity under SSP245 and SSP585 scenarios will likely be higher than SSP126. (3) The spatial variation of meteorological drought in the Yellow River Basin is heterogeneous and uncertain in different combination scenarios and periods. The drought tendency in the Loess Plateau will increase significantly in the future, and the drought frequency and duration in the main water conservation areas of the Yellow River Basin was projected to increase.

“Se puede vivir sin respirar”. Contexto teórico y marco práctico de los buzos en la Real Armada española en el siglo XVIII
Authors: García Hurtado Manuel-Reyes
Published: June 2022

Analizamos la producción escrita y los principales instrumentos y máquinas ideados a lo largo de la Edad Moderna en Europa destinados a posibilitar el aprendizaje de la natación y del buceo, así como las técnicas médicas en el siglo XVIII para reanimar a los ahogados. En este contexto cultural, material y científico, a raíz del naufragio del navío San Juan de Alcántara en 1786 se plantea en España la necesidad de crear escuelas de buceo en los tres Departamentos de la Armada (Cádiz, Ferrol y Cartagena). Esta iniciativa será la primera a nivel mundial, pero su desarrollo y efectos fueron muy limitados, lo que supuso un elemento más de debilitamiento de la Armada a finales del Antiguo Régimen, ya que los buzos eran tan esenciales en los arsenales y en las embarcaciones como siempre fueron absolutamente insuficientes.

Sociabilidad y poder local: los Bomberos Voluntarios de General Sarmiento (1945 -1983)
Authors: Ballester Guadalupe
Published: June 2022

Este artículo se enfoca en el funcionamiento dela Sociedad Cuerpode Bomberos Voluntarios del ex partido bonaerense de General Sarmiento durante el período 1945 – 1983. Esa entidad ha ocupado un lugar de relevancia en la vida cotidiana de la localidad pero además fue un actor clave de las intricadas redes de poder local. Aquí se reconstruyen su surgimiento, desarrollo y las relaciones establecidas con otras instituciones y con el municipio. Se plantea que los vínculos institucionales y personales establecidos entre Bomberos y otros actores del poder local fueron la base del crecimiento de la entidad. La hipótesis que se propone es quela Sociedad B.V.G.S mantuvo un vínculo íntimo y nodal con el gobierno municipal, que fue uno de los principales sostenes económicos e institucionales de la entidad con independencia de los recambios de autoridades. Esta relación se vio complementada, especialmente durante los años setenta y ochenta, con lazos establecidos por Bomberos con la guarnición militar Campo de Mayo. A partir de este estudio de caso se espera contribuir a un mejor conocimiento de la controversial temática de la relación entre Estado y sociedad durante el pasado reciente argentino.

The arbitrary electron energy distribution function (EEDF) of cold atmospheric-pressure plasma is determined from optical emission spectroscopy measurement. Using the electron-neutral bremsstrahlung-dominated continuum spectrum and relevant cross-section data, a partial arbitrary EEDF can be reconstructed through the reinforcement learning-based visible bremsstrahlung inversion method. From an atmospheric-pressure argon dielectric barrier discharge plasma emission spectrum (440–900 nm), a partial arbitrary EEDF can be determined with a resolution of 0.2 eV. The resemblance between the obtained arbitrary EEDF and a two-temperature Maxwellian was found with
