Synergistic effects of microbes and plant for remediation of chromium contaminated soil

by

Dr. V. Ravisankar et al. View all

Soil and groundwater contamination and remediation

The contamination of soil is a serious issue to the environment caused by the human activities in the form of improper disposal methods. There are several contaminated dumpsites in India where, hazardous and other wastes contains heavy metal were dumped historically, which subsequently results in...

Transport of alumina nanoparticles in natural waters and water saturated porous media- an analysis of the effect of various environmental parameters

by

Mrudula Pulimi et al. View all

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

by

Sunwanee Jijai et al. View all

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...

Efficiency of Food Waste Activated Carbon in Treating Biodiesel Plant Effluent: Impact on Process Conditions and NaOH Recovery

by

Dawn S S et al. View all

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.

by

Ioannidis I. et al. View all

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

by

R. Mafaz Ahamed et al. View all

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...
