British Petroleum Site Day Treatment Process

British Petroleum Site Day Treatment Process

Pumped ground water passes through a forced-bed cascade aerator to enhance contaminant volatilization and ferrous iron oxidation. Aerated water is directed through subsurface pipes to one of two parallel free-water surface wetlands, and then passes through additional subsurface pipes to one of two center-feed treatment beds. From there, water radiates under natural hydraulic conditions toward the bed perimeter while undergoing both biodegradation and phytoremediation (including phytovolatilization).
