In the endorheic basins of Altiplano, water is crucial for sustaining unique ecological habitats. Here, wetlands act as highly localized evaporative environments, and little known about processes that control evaporation. Understanding evaporation in Altiplano challenging because these environments are immersed a complex topography surrounded by desert affected atmospheric circulations at various spatial scales. Also, may be subject to enhancement events result dry air advection. To better...

Anthropogenic fecal pollution in urban waterbodies can promote the spread of waterborne disease. The objective this study was to test crAssphage, a novel viral human marker not previously applied for source tracking Latin America, as an river Chile. Human markers crAssphage CPQ_064 and Bacteroides HF183, pathogen norovirus GII, culturable indicator bacteria (FIB) were quantified at six locations spanning reaches Mapocho River from upstream downstream Santiago, well repeated sub-daily...

ABSTRACT: AlgaeSim , a dynamic multiple‐systems (C, N, P) mass balance model, was developed to explore the potential for algae biomass production from wastewater by coupling two photobioreactors into main treatment train at municipal resource recovery facility (WRRF) in Tampa, Florida. The scoping model examined synergy between cultivation and through algal growth substrate removal kinetics, as well macroeconomic analyses of conversion bioproducts. Sensitivity showed that is strongly...

In this study, a composite bioactive membrane was developed and tested to generate capture hydrogen (H₂) during the process of wastewater treatment.

Removal of polychlorinated biphenyls (PCBs) from contaminated sediments is a priority due to accumulation in the food chain. Recent success with reduction PCB bioavailability adsorption onto activated carbon led recognition situ treatment as remediation approach. In this study, reduced and subsequent break-down PCBs dehalorespiring biofilms was investigated using Dehalobium chlorocoercia DF1. DF1 formed patchy biofilm ranging thickness 3.9 6.7 µm (average 4.6 ± 0.87 µm), while coverage...

Polycyclic aromatic hydrocarbons (PAHs) are a family of organic compounds widespread presence in the environment. They recalcitrant, ubiquitous, prone to bioaccumulation, and potentially carcinogenic. Effluent from wastewater treatment plants (WWTPs) constitutes major source PAHs into water bodies, their should be closely monitored, especially considering increasing applications potable non-potable reuse treated worldwide. Modeling fate distribution WWTPs is valuable tool overcome complexity...

By mimicking the complex organic matter composition in sewage, COPAS is a readily available and practical alternative anaerobic lab-scale studies.

In many cities in Vietnam, wastewater generated slaughterhouses is normally discharged directly into surface waters without treatment. Management of slaughterhouse (SHWW) difficult due to the lack infrastructure for conveyance centralized facilities. On-site treatment presents one cost-effective way managing SHWW compared mass improvement infrastructure. This study evaluates application an airlift membrane bioreactor (AL-MBR) on-site SHWW. The concentrations chemical oxygen demand (COD),...

While Chile faces a mega-drought, wastewater reuse emerges as an alternative solution. In this study we develop set of indicators for the comprehensive sustainability assessment application advanced treatment technologies (e.g., MBRs) in project Chile. The methodology is based on Integrative Concept Sustainable Development (ICoS) framework. A critical analysis presented terms benefits (The Good), difficulties Bad), and barriers (the Ugly) their development potential application....

In the global race to produce green hydrogen, wastewater-to-H2 is a sustainable alternative that remains unexploited. Efficient technologies for are still in their developmental stages, and urgent process intensification required. our study, mechanistic model was developed characterize hydrogen production an AnMBR treating high-strength wastewater (COD > 1000 mg/L). Two aspects differentiate from existing literature: First, input multi-substrate includes fractions of proteins, carbohydrates,...

Gas-lift Anaerobic Membrane Bioreactor (Gl-AnMBR): Preliminary Results From a Filterability AssessmentThe membrane bioreactor (MBR) is generally known for its high quality effluent and small footprint. Compared to aerobic counterparts, the anaerobic MBR (AnMBR) has additional potential of energy generation (e.g. biogas), fertilizer recovery nutrients), low sludge generation. Under optimal operational conditions, an AnMBR can be used not only on-site wastewater treatment, but...Author(s)Ana...
