this study evaluates the efficiency of biological treatment of fish pond wastewater (fpww) using a laboratory-scale aerobic bioreactor inoculated with two bacterial strains—pseudomonas aeruginosa and bacillus cereus—isolated from dairy plant sludge. these strains were selected for their high biodegradation potential and applied to separate bioreactors, each containing 2 l of fpww. a non-inoculated

solar collectors play a crucial role in harnessing solar radiation and converting it into thermal energy, functioning as efficient heat exchangers. among them, solar dish concentrators are particularly notable for their ability to operate at high temperatures, making them an effective solution for both heat and electricity generation. owing to their high efficiency in capturing and utilizing solar

cadmium (cd) pollution poses a significant hazard to the ecosystem due to its toxicity and non-biodegradability. this research used novel indigenous bacteria widely isolated from tempe lake in south sulawesi, indonesia, for cadmium reduction. bacterial identification was performed using the 16s rdna method. measurement of cd reduction was performed using atomic absorption spectrometry (aas). results

to change the behavior of users of diminishing groundwater resources toward its conservation, it is necessary to identify the psychological factors affecting farmers as the main users of these resources. this study identifies the psychological factors influencing iranian farmers' intention to conserve groundwater resources in the restricted plain of rumeshkan. this study was conducted using a cross-sectional

southern new jersey, the usa, particularly its coastal regions, faces rising flood risks due to frequent and extreme weather events associated with climate change. interactions between rainfall and runoff remain challenging due to data limitations and variability in hydrological conditions. this study integrates precipitation data and watershed characteristics in a hydrologic model to assess flood

the drinking water supply in rural communities needs efficient, appropriate, low-cost, and adaptable technologies to local conditions. this research investigates a household prefiltration system composed of a dynamic gravel filter, a rapid sand filter, and a slow sand filter. this study evaluates the under varying turbidity, organic carbon, and microbial contamination conditions. kaolin and humic acids

evaluating the conditions of groundwater aquifers periodically, along with good management of the withdrawal and use of groundwater aquifers, is considered extremely important. the current study uses pumping test data to re-evaluate and determine the extent of change in the nubian sandstone aquifer system (nsas) conditions with over-pumping operations, as it is considered the main aquifer in el-kharga

a huge amount of untreated or partially treated wastewater (come from industrial, agricultural and human activities) is released into the water bodies with dangerous impacts on aquatic life, human health and environment. traces of organic contaminants (called persistent organic pollutants) were also found in water bodies, and they cause adverse ecological and human health effects. in addition, several

the aim of this study was to develop a catchment scale water balance model capable of simulating water balance components (wbcs), with a specific focus on data-sparse environments. using the soil and water assessment tool (swat), an open-source semi-distributed hydrological model, the wbcs dynamics simulated by integrating decadal land-use and land-cover (lulc) changes, daily meteorological inputs

the electro-peroxone process, as an advanced oxidation technology, has gained increasing attention for its effectiveness in wastewater treatment and pollutant removal. this process combines electrochemical oxidation with the in situ generation of hydrogen peroxide through electrolysis, which significantly enhances the degradation of contaminants. the objective of this study is to conduct a systematic

understanding the status of watershed erosion is essential for effective watershed management and sustainable water resources utilization. this study aimed to determine the erosion vulnerability of the gelda entire watershed and its 26 sub-watersheds within the tana sub-basin, ethiopia, using hypsometric analysis. the data analysis began processing a 12.5 m by 12.5 m digital elevation model (dem) in

this research proposes the use of machine learning tools to assess groundwater quality in the semiarid mediterranean region of murcia, spain, with a focus on the risk of aquifer salinization. two groundwater quality indices were defined: one for drinking water (dwqi) and another for irrigation purposes (iwqi), calculated using ten and fifteen parameters, respectively. the weights of the parameters

rivers play a critical role in regional and global carbon balances, which have been altered by decades of human activity, such as dam building. however, few studies have examined the long-term changes in lateral multispecies carbon export from historically sediment-transporting rivers in response to dam construction. therefore, we aimed to delineate the multidecadal alterations in the lateral export

long-term runoff forecasting (lrf) holds substantial importance in water resource management. global climate indices (gcis) and local weather variables (lwvs) driven deep learning (dl) models are the primary approach for lrf. and the interpretability analysis of dl models provides valuable insights into runoff mechanisms. however, high-dimensional gcis and lwvs exhibit redundancy and multicollinearity

human parainfluenza virus (hpiv) and human rhinovirus (hrv) significantly contribute to acute respiratory tract infections (aris), especially in children. wastewater surveillance (wws) is a valuable tool for monitoring these viruses, but limited understanding of their fecal shedding patterns restricts the broader application of wws. this study aimed to investigate fecal shedding dynamics of hpiv and

livestock wastewater is a critical reservoir of antibiotic resistance genes (args) that poses significant public health risks. this study comprehensively evaluated the seasonal dynamics and associated risks of args in a full-scale livestock wastewater treatment plant using an integrated metagenomic and metatranscriptomic approach. the results showed that untreated livestock wastewater harbored high

the hydrogen isotopic composition of plant α-cellulose (δdcell) could help us to understand past hydrological and ecological processes via unraveling plant-water interactions. however, such paleo-hydrological proxy indicator was rarely applied in natural archives relative to carbon and oxygen isotopes. this study reported strong relationships of δdcell of a predominant sedge plant (carex pamirensis)

water diversion projects are crucial to the reallocation of essential water resources on a worldwide scale. clarifying the dynamics and controlling mechanism between water quality and aquatic organisms along the diversion channel is a prerequisite for water quality security, the early warning of biohazards and sustainable management, but our understanding of these relations is limited. here, edna amplification

the complexity of karst terrains, combined with aquifer heterogeneity and extensive anthropogenic activities, results in the diversity of groundwater response, which hinders our understanding of the karst hydrological processes of precipitation-driven spring discharge. this study first transforms precipitation and karst spring discharge signals into the time–frequency domain using wavelet analysis

urban environments contend with an array of stressors, including salinization by deicing road salts. to advance understanding of how road salt pollution affects aquatic ecosystem functioning, we surveyed primary producers in 50 stormwater ponds in brampton, canada. we found that chloride concentrations decreased (benthic) periphytic algal biomass but had no detectable effect on the total biomass of
