A system for recovering bioremediation material comprises a series of tanks 40, 30, 20, each with a lip on one edge of the settlement tank, forming weirs 28 for conveying bioremediation material and pollutants from one settlement tank to the next in series. An input 14 is provided to the first settlement tank. The final settlement tank in the series may have a weir or lip 88 to a tank, which can include an adjustable skimmer 50 feeding a funnel and out of the tank. The tanks may be emptied onto inclined ramps 29 on which grit and heavy hydrocarbons are deposited, as material is conveyed from one tank to the next. A further weir may extend upwards from the bottom of the tank over which recovered bioremediation material flows as the first tank fills, to a further tank. The further tank may have a further weir leading to a third tank 40. The bio-remediation method may involve applying a surfactant and a hydrocarbon to a polluted surface such as a car in a carwash, and subsequently applying a bioremediation material before entering input 14. |
