Grease trap scum, oil-based, but also contains water and some solid impurities. Industrial waste oil, moisture content and sometimes up to 50%, other impurities generally about 1% to 20%. Relying solely on the density difference between the oil droplets and water is performed to generate the floating oil and water separation, the oil removal efficiency is generally about 70% to 80%, the grease trap effluent still contains a certain amount of emulsified oil and attached to the suspended solids oil, generally more difficult down emissions standards below. Flotation separation of oil and water is better standard grease traps, the oil content of the water is generally less than 20mg / L. For small grease traps rail transport, chemical and other industries, the skimming device is to rely on the density difference between water and oil to form a level difference and achieve automatic skimming purposes. Advection grease trap design and advection sedimentation tanks are similar, according to the design surface load, generally use 1.2m3 / m2 & *** dot; h; according to the design of the residence time, the general 2h. Gravity type of oily wastewater treatment grease trap is the most commonly used devices, which process is placed in a pool of oily wastewater gravity oil-water separation, then, excluding oil wastewater surface. Theoretically gravity separation process can be represented by the Stokes equation. But often occurs due to turbulence and short cycle, the actual efficiency depends on the gravity separator design and waste water conservancy reasonable residence time. Stay longer stainless steel grease traps, floating oil and water separation, the better. When the residence time is less than 20min, oil-water separation efficiency of less than 50%, if the extension of the residence time can improve the separation. Grease traps can be set slick water discharge pipe buried grease traps can also be used ,, excluding machinery, small grease traps are also used in artificial skimmers West Baoquan _ _ stainless steel grease trap grease trap from Xi'an West Baoquan water available.
