Grease Water Separator

Stormwater or wastewater containing oil grease or other total petroleum hydrocarbons tph enters the underground precast concrete coalescing separator through the inlet pipe.

Grease water separator. Therefore all waste water from kitchen areas i e. The retention time of the water inside the separator is much longer than that for a grease interceptor allowing more time for the separation to occur. Fat and oil mainly get into the waste water via food residues. Short circuiting is produced when water is allowed to pass under the inlet baffle and along the bottom of the separator directly to the outlet at a velocity too high to permit grease separation.

As fluid enters the first chamber preliminary sedimentation and oil removal occur. Therefore grease separators are crucial for wastewater management systems. They have internal structures that facilitate the binding of oil droplets together. They are available in two or three compartment configurations.

This undesirable condition is encountered when the evacuation and or ejection of solids from the separator is attempted along with grease separation. A stopper in the spout keeps liquid from entering the spout as the cup is filled so very little fat will enter the spout. Industrial grease traps or oil water separators are commonly used where industrial floor drains are subject to the collection of motor oil transmission fluids hydraulic oils grease etc. Meanwhile the strainer top keeps large pieces out of the liquid.
