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.

Recently GN Company finished production for 8 sets of Mud Recycling Plants, and would arrange final delivery to client’s work site.

GN Mud Recycling Plant is widely used for Bored Piling, TBM, HDD (trenchless), and water well drilling etc., with working capability ranges from 50~3000m3/h.

The Mud Recycling Plant mainly includes Double Mud Shaker, Desander/Desilter, and Centrifugal Pump.
Mud Shaker is used to remove big size of Solids from the Slurry.
Desander/Desilter is used to recollecting Mud for reuse.
Centrifugal Pump is used to pump slurry to Mud Shaker.

GN Mud Recycling Plant Working Procedure as below,

  1. Feeding mud to Shale Shaker from the mud pit. The mud would be feed onto the bottom layer screen of shale shaker (3) through buffer box(2), then the coarse particles would be separated out, while the mud would flow to mud storage tank (4) through the bottom layer screen of shale shaker(3).
  2. The centrifugal pump (5) sucks mud from the mud storage tank (4), and feeds to desander/desilter cone (6) with pressure used for centrifugal separation, the solids/sand would be discharged onto the upper shaker (3) from the outlet nipple of the desander/desilter cone, and fine solid would be separated out. (The screens of Upper and bottom would be different, and the Upper screen’s mesh would be higher)
  3. The mud passed the upper shaker screen would return back to mud storage tank (4), while the clean mud would enter into intermediary tank (7) through desander/desilter cone overflow pipe. The mud in the intermediary tank (7) would go out through outlet pipe (9) or go back to mud storage tank (4) depends on the fluid level in the recycling tank.
  4. In the mud circulation process, there is a fluids level float switch (8) between intermediary tank (7) and mud storage tank (4), it can balance the fluids level in the mud storage tank (4). When mud level is low in the mud storage tank (4), the overflow from the desander would enter into mud storage tank (4) through the intermediary tank (7). When the mud level is too high in the mud storage tank (4), the mud would overflow to the intermediary tank (7) and go out from the outlet pipe (9).

Recently GN Company finished production of 2 units of Drilling Cuttings Management Systems for Xinjiang, China client, and would arrange shipment to client’s work site soon.

The Drilling Cuttings Management System is used for recovering drilling fluids from drilling cuttings as much as possible for reuse, which can save cost and protect environment.

There are two kinds of Drilling Cuttings, Oil based drilling cuttings and Water based drilling cuttings.

For oil based drilling cuttings, GN Company’s System can reduce the oil on the cuttings to 3%-5%.
For water based drilling cuttings, GN Company’s System can reduce moisture content for easy transportation.

This Xinjiang client ordered Oil Based Drilling Cuttings Treatment System. Oil Based Drilling Cuttings Treatment System includes two parts, cuttings drying module and fine solids removing module.

Cuttings Drying Module, its key equipment is Vertical Cuttings Dryer. Its working procedure is feeding Drilling Cuttings into Vertical Cuttings Dryer, then separating oil from cuttings, and passing through the screen opening to the collection groove inside the dryer unit, it is achieved by centrifugal force.
Opening size of the dryer screen is designed of 250, 350 and 500 microns as options for different size cuttings drying. And vertical cuttings dryer is equipped with flushing system and air knife system for cleaning of the mud collection groove and screen, in order to avoid block.

Fine Solids Removing Module, its key equipment is decanter centrifuge. The liquid effluence discharged from the cutting dryer would be pumped into decanter centrifuge for polishing treatment to remove the fine solids in drilling fluids. GN Company can manufacture decanter centrifuge from 9 inch (220mm) ~ 30 inch (760mm), with bowl length and diameter ration up to 4.2, and adjustable G force up to 3000G, for reaching client’s requirement in different projects.
