In this study, a bioremediation approach was evaluated for the decontamination of an aquifer affected by release organohalides industrial landfill. After preliminary physicochemical and microbiological characterization landfill groundwater, stimulation natural organohalide respiration addition reducing substrate (i.e., molasse) tested both at microcosm field scales, placement anaerobic permeabl...

In this study we investigate the model uncertainties involved in predicting long-term permeable reactive barrier (PRB) remediation efficiency based on a lab-scale column experiment under accelerated flow conditions. A PRB consisting of 20% iron and 80% sand was simulated in a laboratoryscale column and contaminated groundwater was pumped into the column for approximately 1 year at an average gr...

Reactive oxygen and nitrogen species (RONS) are involved in many biochemical processes, including nitro-oxidative stress that causes cancer cell death, observed therapies such as photodynamic therapy cold atmospheric plasma. However, their mechanisms of action selectivity still remain elusive due to the complexity biological cells. For example, it is not well known how RONS generated by permeat...

Batch tests were performed to evaluate the effects of inorganic anion competition on the kinetics of arsenate (As(V)) and arsenite (As(III)) removal by zerovalent iron (Peerless Fe0) in aqueous solution. The oxyanions underwent either sorption-dominated reactions (phosphate, silicate, carbonate, borate, and sulfate) or reduction-dominated reactions (chromate, molybdate, and nitrate) with Peerle...

Leachate pollution index (LPI) value can be used as a tool to assess the leachate pollution potential of landfill sites particularly at places where there is a high risk of leachate migration and pollution of groundwater and thus can help to take necessary decisions as deem fit. In this paper, leachate treatment efficiency was evaluated on the basis of LPI value of leachate before and after tre...

t-shape profile barriers are one of the most successful barriers among many different profiles. it has been shown that using welled diffusers on the top of t-shaped barriers makes a reactive barrier that shows better performance than that of any other used profile barriers compared with their equivalent absorbent barrier. the contribution of the top surface of reactive t-profile barriers to the...
