Millions of people worldwide are exposed to excessive concentrations fluoride (F−) from groundwater sources. Ca-Al-CO3 layered double hydroxides (LDHs) have shown promising defluoridation efficiency; however, by LDHs is highly pH sensitive. This study showed that simultaneous acidification conventional acids, such as HCl and CO2 substantially increased the performance for F- removal at environm...

Continental flood basalts (CFB) are considered as potential CO2 storage sites because of their high reactivity and abundant divalent metal ions that can potentially trap carbon for geological timescales. Moreover, laterally extensive CFB are found in many place in the world within reasonable distances from major CO2 point emission sources.Based on the mineral and glass composition of the Columb...

Geothermal energy has been a subject of great interest since the 1990s in Upper Rhine Graben (URG), where first European Enhanced System (EGS) pilot site developed, Soultz-sous-Forêts (SsF), France. Several studies have already conducted on scales occurring at reinjection side geothermal plants located URG. It observed that composition changes as chemical treatment is applied to inhibit metal s...

The sorption of Ra on Olkiluoto biotite in the context deep geological disposal spent nuclear fuel was studied with isotherm batch experiments. Ba used as an analog for experiments and modeling studies. A wide concentration range Ra/Ba studies (2.6 × 10?9 M to 1 10?3 M) addition four different reference groundwaters salinity types ranging from fresh saline. Experimental results show that both s...

Abstract GeoChemFoam is an open-source OpenFOAM-based toolbox that includes a range of additional packages solve various flow processes from multiphase transport with interface transfer, to single-phase in multiscale porous media, reactive mineral dissolution. In this paper, we present novel solver for simulations on complex pore geometries, including microfluidic devices and micro-CT images, i...

Groundwater contamination by chlorinated hydrocarbons is a worldwide problem that poses important challenges in remediation processes. In Italy, the Legislative Decree 152/06 defines water quality limits to be obtained during cleanup process. situ bioremediation techniques are becoming increasingly due their affordability and, under right conditions, because they can more effective than convent...

Loess-paleosol bluffs can be unstable, but in the course of urbanization, houses may built such locations to take advantage view. One factor affecting stability is water, role which mass movements well established. In this study, connection meteorological conditions, as rainfall and subsequent water level changes, was researched using new statistical methods. The periodicity Danube analyzed wav...
