Draw Date AM 14 March 2013 Sheet Size Scale Drawing No Sheet No A4 1:250 MMI-001-WWT 1 of 1

The document is a drawing for an oil and grease interceptor facility. It contains information about how an oil and grease separator works to purify contaminated water in a few steps. First, contaminated water enters the tank where the sludge sinks to the bottom and is removed. Then in the second tank, oil is separated from the water as larger oil drops rise to the surface due to their low density and smaller droplets coalesce and also rise to the surface to be removed. The purified water then exits through the lower outlet.

The effects of oil on water and the environment.


When released into a ditch, oil forms a thin layer on the water surface as a result of its lower density. Then the oil emulsifi es in reaction to the water. The resulting emulsion releases toxic elements, which causes enormous problems for the environment. When oil penetrates into the soil, the well being of flora and fauna runs a great risk. Consider for example the dramatic effects on the population of fi shes and nestling birds. The purifi cation process of contaminated water takes a long time. How Daes it works ? Inside the Sludge Separator the following steps will take place: The water contaminated with oil and sludge enters the tank 11 . Due to the special construction Pipelife water distribution system 22 ,the water will evenly be distributed through the tank 3. The sludge sinks to the bottom of the tank 3 . When the water enters the outlet of the fi rst tank, the sludge has been removed 4.Inside the second tank, the oil is separated from the water. The contaminated water enters the separator 5 5 . Due to the specific construction system 6 6 , the water and oil are evenly distributed. The bigger oil drops will rise to the water surface due to their low density. The smaller droplets will coalescense and grow in size in the fi lter 77 , and they will eventually rise to the surface. Now external companies can remove the oil 8 8 . By doing so the water leaving the lower outlet is free from oil 9
