Transport of alumina nanoparticles in natural waters and water saturated porous media- an analysis of the effect of various environmental parameters
Water Quality
To control the use and disposal of products containing nanoparticles and lessen the risks they pose to soil and aquatic ecosystems, it is essential to understand the fate and transport of Al2O3 NPs. The stability, settling, retention, and transport of Al2O3 NPs in aqueous environments and saturated...

Kinetic Model of Anaerobic Digestion from Chicken Manure and Thai Rice Noodle Wastewater in Continuous Reactors
Environmental data analysis and modelling
A kinetic model was used to describe the anaerobic co-digestion of chicken manure (CM) and Thai rice noodle wastewater (TRNW) in continuous reactors. This research investigated the effects of mixing interval and hydraulic retention time (HRT) on methane production and other related kinetic...

Improving heavy metal removal efficiency from steel sludge: Application of the coupled ultrasonic-bioleaching treatment
Water and Wastewater Treatment
This study assessed the efficiency of Fe, Al, Ni and Sr removal from the steel sludge using the coupled bioleaching with Thiobacillus thiooxidans and ultrasonic waves. Growth conditions were optimized using the surface response method. The bacterium was adapted successively to three heavy metal...

Efficiency of Food Waste Activated Carbon in Treating Biodiesel Plant Effluent: Impact on Process Conditions and NaOH Recovery
Water and Wastewater Treatment
In work illustrated, the mixed food reject was carbonized and further activated with zinc chloride for biodiesel washwater treatment experiments. Biodiesel washwater is one of the significant side streams generated during biodiesel production from waste cooking oil. The food waste activated carbon...

The effect of temperature on the U-232 and Am-241 adsorption by PN6 microplastics in aqueous solutions.
Microplastics in the marine environment
The effect of temperature on the adsorption of U-232 and Am-241 by PN6 has been investigated in laboratory and environmental water samples (e.g. seawater and waste water) in the picomolar concentration range. Generally, increasing temperature favors radionuclide adsorption, indicating that...

Vigna stipulacea mediated Fe nanoparticles synthesis: A greener approach for sequestration of Pb2+ from aqueous environment
Water and Wastewater Treatment
The greener approach offers a viable, sustainable and eco-friendly way to synthesize nanoparticles. This study used the seed extract of Vigna stipulacea (VS) as a bioreducing agent to synthesize iron nanoparticles (VS-Fe). The VS seed extract contains polyphenols and lignin content that acted as a...

Trace Metals Pollution in Ambient Air of Urban and Rural Coastal Environments
Environmental data analysis and modelling
Air pollution in coastal areas will have a different pattern from mountainous areas due to different wind patterns during the day and night. The city of Semarang, as a representation of urban areas, and Jepara Regency, as a representation of the rural regions, were chosen for this sampling. 24-h...
