Design, Construction, and Operation of Tailored Permeable Reactive Barriers

Influence of dissolved inorganic carbon and calcium on gas formation and accumulation in iron permeable reactive barriers

“…All solutions receiving ions (except for column S2B) were adjusted to a neutral pH value of 7 by addition of hydrochloric acid; the pH 9 of the feed solution for column S2B was adjusted by addition of potassium hydroxide. Columns were filled with 150 g granulated cast iron (nominal grain size 300-2000 μm, Gotthart Maier, Germany) which has been used in a number of laboratory investigations (Ebert et al, 2006;O et al, 2009;Rosenthal et al, 2004;Van Nooten et al, 2007) and field applications (Birke et al, 2003a(Birke et al, , 2003b. Column S2S (75 g) and column S2L (270 g) contained different amounts for elucidation of the relative influence of column length.…”

An overview and analysis of site remediation technologies

“…Treatment walls are structures installed underground to treat the contaminated groundwater found at hazardous waste sites (Suthersan, 1997;Birke et al, 2003;Baciocchi et al, 2003). Treatment walls rely on the natural movement of water to carry the contaminants through the wall structure (Nyer, 1996).…”

“…Target contaminant groups for passive treatment walls are VOCs, SVOCs, and inorganics (FRTR, 1999c). The specific filling chosen for the wall is based on the contaminant found at the site (RAAG, 2000;Birke et al, 2003). Guerin et al (2002) have discussed an interesting application of reactive barrier technology to petroleum hydrocarbon contaminated groundwater.…”

Performance of a Sequential Reactive Barrier for Bioremediation of Coal Tar Contaminated Groundwater

“…However, reports available detail a PRB containing peat for the removal of petroleum hydrocarbons (n-alkanes and BTEX) by sorption and aerobic biodegradation processes in Southeast Australia (11) and a PRB containing aerated sand at a FMGP site in Portadown, Northern Ireland (12). A PRB for the removal of PAH and BTEX by sorption onto granular activated carbon (GAC) has also been installed in Germany (13).…”
