Interpretations and Explanations

An oil trap is installed in a plumbing drainage system to prevent oil based substances from entering the authority’s sewer network. The oil tap is a retention tank fitted with baffles or below surface path ways which separates the oil from the waste water, by forcing the waste to travel along the bottom of the tank. The separation process works because the oil is less dense than the water. The oil floats to the top. New technologies are available where electronic pulse systems use electro coagulation as a means of oil separation (WHO 2006).
