Recently one unit of GNOST-15B Oil Sludge Treatment Package Equipment are ready for shipment to Beijing client. The package including:

1 unit of oil sludge separation shale shaker GNZS594F, with spray system and sealing cover. The function is to separate the coarse solids and reduce solids content from oil sludge, by mixing with proper chemicals, the oil will be easily removed from solids.

1 unit of big bowl big volume 2 phase decanter centrifuge GNLW554ET-VFD, to separate fine solids from oil sludge, by mixing with proper chemicals, the ultra fine solids can be easily separated, the mixture liquid with oil and water will be collected in a tank for further treatment.
1 unit of big bowl 3 phase decanter centrifuge GNSX554ET-VFD to separate oil, water and solids
The whole oil sludge treatment package including pre-mixing modular, coarse solids separation modular, solids liquid 2 phase separation modular, solids oil water 3 phase separation modular.

The 3 phase decanter centrifuge working principle is sedimentation, the solid with specific weight precipitate.When the material enters the high speed rotating bowl, the oil sludge rotates synchronously with the bowl. Based on the different specific gravity and centrifugal force, the solid with the bigger gravity with biggest centrifugal force, the heavy phase liquid (water) and the light phase liquid (oil). The centrifugal force is becoming less from outside to inside, one concentric solid layer and two liquid layers are formed. Solids are pushed out and liquids are removed from their respective nozzles.
When the client’s required result of recovered oil, water and discharged solids is not very high, 3 phase decanter centrifuge can be used to replace the package of 2 phase decanter centrifuge plus 3 phase disc centrifuge. If they want the better treatment result, 3 phase disc centrifuge should be applied to separate oil and water.
