As one of the most popular treating equipment, GN Solids Control has been providing oil sludge treating systems for worldwide customers for many years. GN Solids Control this week finished manufacturing of one set 2 m3/h oil sludge system for one Fujian client in China. 
To get the oil and water clearly, GN Solids provides one 3 phase disc-separator GNSD-40 after the two phase decanter centrifuge.
GN 2 m3/h oil sludge treating unit is a demo treating unit, in a compact design so it move easily among different sites. And GN Solids Control also provides much bigger standard treating unit like 5m3/h and 15 m3/h which can treat the oil sludge continuously. Usually based on the site usage,
GN Solids Control customize the oil sludge treating system so the customer can have a cost-effective solution. GN Separation Unit is a 3 phase treating unit, it can separate the oil sludge into 3 clean phases: oil, water and solids. After pretreated, oil sludge it pumped into a coarse shaker GNZS752J so the larger solids in the oil sludge can be removed first, usually solids larger than 100 microns can be removed by the shaker but varies on the shaker screens fixed on the shaker deck.
Effluent from shale shaker is feed into a 9 inch bowl decanter centrifuge GNLW224, where solids above 2-5 microns can be removed with the help to polymer more fine particles are eliminated from the liquid.
How does this system run?
Firstly, the feeding material will be fed to the vibrating screen to discharge soil solid, the tiny oil sludge fall down to the tank.
Step2: To feed water to the tank until the gravity for water,oil,solid hits the proper level.
Step 3:The mixture will be pumped to the shale shaker to discharge the remaining solid as much as possible, after the previous 2 discharge process, the solid gravity will be limited to a relatively-lower level,meanwhile the solid size will be less than 7um.
Step4:Before fed to the decanter centrifuge,sometimes in order to collect more clear oil, dosing unit will be necessary to help to realize the target while the mixture is being fed to the decanter centrifuge. The discharged oil will be stored temporarily in the oil buffer tank, the discharged water will be stored in the water buffer tank which will be reused in step 2.
Step5: The oil in the buffer tank eventually will be pumped to some big oil tank.
Remark: sometimes one water-steamer is used to heat the mixture tank in order to improve its liquid property before feeding to the decanter centrifuge.
