Forecourt separators and petrol interceptors are an essential infrastructure requirement for all forecourts so as to ensure compliance with both health, safety and environmental legislation.
Fuels and oils such as petroleum and diesel when mixed with water will float to the top when contained in a tank. Car parks, petrol forecourts and motorways are typical places where leaking engine oil and fuel collect over time. When it rains, the run-off water becomes contaminated and can enter drains and man-holes causing serious pollution. Petrol interceptors or oil separators help to solve this problem. The contaminated water enters the interceptor typically after flowing off the road, car park or forecourt and enters a channel before being deposited into the first tank inside the interceptor. The first tank builds up a layer of an oily hydrocarbon as well as other scum.
A typical petrol interceptor has three separate tanks each connected with a dip pipe, as more liquid enters the interceptor the water enters into the second tank leaving the majority of the hydrocarbon behind as it cannot enter the dip pipe, whose opening into the second tank is below the surface. However, some of the oily contaminant mix may enter the second tank. The second tank will not build up as much of the hydrocarbon mix on its surface. As before, the water is pushed into the third tank and more water enters the second. At this stage, the third tank should be clear of any hydrocarbon floating on its surface. As a precaution, the outlet pipe is also a dip pipe and may have a final filter. When the water leaves the third tank via the outlet pipe it should be hydrocarbon free.
