Water contamination caused by heavy metals, nutrients, and organic pollutants of varying particle sizes originating from domestic and industrial processes poses a significant global challenge. There is a growing concern, particularly regarding the presence of heavy metals in freshwater sources, as they can be toxic even at low concentrations, posing risks to human health and the… Continue reading Novel eco-friendly polylactic acid nanocomposite integrated membrane system for sustainable wastewater treatment: Performance evaluation and antifouling analysis
A microbial fuel cell (MFC) is a system that can generate electricity by harnessing microorganisms’ metabolic activity. MFCs can be used in wastewater treatment plants since they can convert the organic matter in wastewater into electricity while also removing pollutants. The microorganisms in the anode electrode oxidize the organic matter, breaking down pollutants and generating… Continue reading Microbial Fuel Cell Construction Features and Application for Sustainable Wastewater Treatment
Highlights: What are the main findings? FTIR analysis showed multiple surface functional groups, e.g., R-OH, OH, -C=O, -COOH, etc., on the biochar surface. FESEM confirmed the randomized and porous tunnel-like structures of biochar. The BET specific surface area was 19.90 ± 1.20 m2/g. Kinetics and isotherm analysis showed alignment with pseudo-second-order kinetic and Langmuir Isotherm… Continue reading Synthesis, Characterization and Performance Evaluation of Burmese Grape (Baccaurea ramiflora) Seed Biochar for Sustainable Wastewater Treatment
Cyanobacteria are interesting microorganisms to produce polyhydroxybutyrate (PHB), a biodegradable plastic similar to polypropylene. In this study, a Life Cycle Assessment and an economic analysis were carried out to assess the sustainability of the process. Different scenarios were analysed including different nutrient sources (i.e. wastewater and standard growth medium BG-11) and different PHB contents (from 15%dcw to 35%dcw and 50%dcw). Regarding the environmental impacts,… Continue reading Life cycle assessment and economic analysis of bioplastics production from cyanobacteria
The continued use of non-biodegradable polymeric-based membranes for water purification has led to an unsustainable accumulation of waste at disposal, resulting in various environmental problems. In this study, eco-friendly asymmetric ultrafiltration (UF) membranes were fabricated from polylactic acid (PLA) with different polymer concentrations using the phase inversion method. The fabricated membranes were characterized using Fourier… Continue reading Asymmetrical ultrafiltration membranes based on polylactic acid for the removal of organic substances from wastewater
Industrial and municipal wastewater treatment has the potential of providing considerable quantities of freshwater for different purposes. Prior to its usage, heavy metal ions elimination from treated wastewater must be ensured to evade their toxic and severe impacts on the water ecosystem and humans. For this purpose, graphene oxide (GO)/manganese oxide (MnO2) nanocomposite was prepared… Continue reading Investigation of Graphene Oxide (GO)-Manganese Oxide (MnO2) Nanocomposite in Metal Ions Adsorption from Wastewater
The first case of Coronavirus Disease 2019 (COVID-19), which is caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), in Europe was officially confirmed in February 2020. On 11 March 2020, after thousands of deaths from this disease had been reported worldwide, the WHO changed their classification of COVID-19 from a public health emergency of… Continue reading Indoor versus outdoor transmission of SARS-COV-2: environmental factors in virus spread and underestimated sources of risk
This review paper aims to identify the main sources of carbon dioxide (CO2) emissions from wastewater treatment plants (WWTPs) and highlights the technologies developed for CO2 capture in this milieu. CO2 is emitted in all the operational units of conventional WWTPs and even after the disposal of treated effluents and sludges. CO2 emissions from wastewater… Continue reading Advances in technological control of greenhouse gas emissions from wastewater in the context of circular economy
The effect of addition of algae to activated sludge as active biomass in membrane bioreactors (MBRs) and electro-MBRs (e-MBRs) for wastewater remediation was examined in this study. The performances of Algae-Activated Sludge Membrane Bioreactor (AAS-MBR) and electro Algae-Activated Sludge Membrane Bioreactor (e-AAS-MBR) were compared to those observed in conventional MBR and e-MBR, which were previously… Continue reading Wastewater treatment and fouling control in an electro algae-activated sludge membrane bioreactor
Considerable attention has been recently given to possible transmission of SARS-CoV-2 via water media. This review addresses this issue and examines the fate of coronaviruses (CoVs) in water systems, with particular attention to the recently available information on the novel SARS-CoV-2. The methods for the determination of viable virus particles and quantification of CoVs and,… Continue reading Coronavirus in water media: Analysis, fate, disinfection and epidemiological applications
