GN Decanter Centrifuge for Oil Sludge Treatment to Environmental Solution Company

Recently one set of GNLW554ET-VFD decanter centrifuge with 3 phase separation centrifuge, and 2 sets of screw pump, all installed on one skid for convenient shipment. The treating capacity is 15 m3/h.
The detailed technical configuration is as below:

1) Decanter centrifuge ( 2 phase separation centrifuge for solids liquid separation) GNLW554ET-VFD
2) Disc centrifuge ( 3 phase separation centrifuge) GNSD-125
3) 2 sets of screw pump, one screw pump as decanter centrifuge feeding pump, one screw pump as flushing pump of disc centrifuge
4) Complete skid with pipelines and accessories to install all the equipments on one skid for convenient shipment

GN solids control can design and produce customized oil sludge treatment unit with different treating capacity, such as 1m3/h, 2m3/h, 5m3/h, 15m3/h. According to the material information provided by the client, we can decide if all the modular should be utilized or not. Basically a general oil sludge treatment unit including oil sludge picking pump ( vacuum pump ) , pre-mixing tank modular, coarse shaker tank modular, dewatering unit modular, 3 phase separation modular, etc. the customer bought 3 phase separation unit modular, they will use the filter before feeding to the decanter centrifuge, otherwise they should ensure the max solids content should be less than 30% and max solids content is smaller than 1 microns. The less solids content, the better separation efficiency. The decanter centrifuge should separate the solids as much as possible, the fluids enter into the disc centrifuge should be with solids content less than 3% and max solids size no bigger than 5 microns, to avoid any damage of the vertical centrifuge.
Depends on the oil sludge conditions, the user can use proper chemicals, they can select to buy dewatering unit from GN or user their own chemical dosing unit by adding chemicals into the oil sludge, to increase the treating efficiency.
