Witryna20 maj 2024 · For benzene selected as the contaminant of concern, greater LNAPL extraction rates were achieved when the initial LNAPL thickness was large (>1.5 m) or in aquifers of high permeability (>2.45 × 10-10 m 2). Importantly, it was discovered that in highly permeable coarse sand and gravel, the submerged pump ought to be placed … WitrynaThe actual thickness of lighter-than-water non-aqueous phase liquid (LNAPL) on the groundwater table is always different from the apparent thickness (measured in the …
