Interpretations and Explanations

A grease interceptor uses the same physics, which grease and oil are lighter than water and will rise to the top when allowed to stand for a time. The devices all have a retention tank designed with an inverted weir at the outlet in order to allow the waste water out but not the grease. An interceptor is designed to separate and hold the grease within the interceptor. A grease interceptor must be emptied if its performance is reduced by a build up of grease. The grease can be removed periodically to a safe treatment or disposal site by either scooping or pumping (WHO 2006).
