GN Company prepared the final package for 2 sets of Construction Slurry Dewatering System for an American client. This system is used to separate Solid Liquid, and recover clean water for reuse or suitable for discharging.

The system includes 4 modules as below,

1. Waste Collecting and Washing Module
2. Screening Module
3. Desilter Module
4. Centrifuge Module

Detailed Explanation as below,

1. Waste Collecting and Washing Module
   The waste slurry would be discharged onto a coarse screen for large size trash separation. The liquid with fine particles is collected in the tank under the coarse screen.
2. Screen Module
   The liquid is pumped to Mine Shaker, to remove coarse particles. Then the liquid would be pumped to GN Shale Shaker for removing fine solids, with particle size about 100 um.
3. Desilter Module
   GN desilter with hydro cyclone manifold is fixed on a washing tank for further separation of the fine solids, with particle size about 20~45 um. The under shaker of the desilter is same model with GN drying shaker for easy maintenance. The hydrocyclone is using centrifugal force and gravity to separate the liquid and solids. The slurry is pumped into the cyclone with high speed for effectively separation process.
4. Centrifuge Module
   A decanter centrifuge would be used to remove the ultra-fine solids in the slurry, with particle size about 10 um. The liquid discharged from decanter can be reused for this system.
   A chemical dosing system can be used to help decanter centrifuge to increase efficiency of separation.

There is one company from Asia purchasing a complete set of Oil Sludge Treatment System, with Model GNOST-50A, capacity 5m3/h, from GN Company. The system can be used for Oil Sludge Treatment, which from Refinery Plant, Oil Tank, Drilling Project, etc.

GN Oil Sludge Treatment System can reach the achievement of discharging Oil, Water, and Solid separately, and result as follow,
Solid & Water Content in Oil less than 3%,
Oil Content in Solid less than 2%,
Oil Content in Water is about 500~1000 PPM. And we can supply Micro bubble Water Processor, which can lower oil content in water to 50~100 PPM.

The system include 5 Modules as below,

1. Vacuum Transferring Pump Module
   Transferring Oil sludge into our system by sludge Pump
2. Pre-mixing and Heating Module
   Mixing oil sludge with water and chemical, for making Solids Content less than 20%, which is easier for procedure.
3. Screening Shaker Module
   Removing large particle of solids (about 100um) by Shale Shaker
4. Centrifuge Separation Module
   Firstly separating fine solids (less than 10um) from liquid by Decanter Centrifuge (2 phase separation)
   Secondly separating Oil, Water and little ultra-fine Solid by Disc Centrifuge (3 phase separation)
   (Both decanter centrifuge and Disc centrifuge works based on Centrifugal Force, and Disc centrifuge works at a much higher speed, which means bigger Centrifugal Force than Decanter Centrifuge, so that oil and water can be separated)
5. Chemical Dosing System

GN Company is a professional manufacturer of Wastewater & Oil Sludge Treatment Equipment for 11 years, and GN turnkey solution system includes equipment as follow, Decanter Centrifuge, Disc Centrifuge, Oil Water Separator, Sludge/Solids Vacuum Pump, Screw Conveyor, etc.
GN Company has two factories under operation, and a third factory under manufacturing now, with about 100,000 square meters totally.

Welcome to contact GN Company, we would offer working videos about our Oil Sludge Treatment System in job site.

GN Company accepts that clients to do Trial Test with your oil sludge in our work plant, for checking system working performance actually.
