GN Solids Control Co., Ltd. is a Chinese company specializing in the design, manufacturing, and service of solid control systems and related equipment for the oil and gas drilling industry.

GN Solids Control provides specialized mud recycling systems for trenchless drilling (HDD, microtunneling, pipe jacking) to maximize fluid reuse, reduce costs, and minimize environmental impact.

Why Use a Mud Recycling System in Trenchless Drilling?
Recovers expensive drilling fluids (bentonite, polymers).

Reduces disposal costs of waste slurry.

Maintains optimal mud properties for lubrication and bore stability.

Prevents jobsite pollution (compliance with EPA, local regulations).

Key Components of GN’s Trenchless Mud Recycling System

1. Shale Shaker (Primary Solids Removal) GNZS Linear Motion Shaker

Removes coarse cuttings (≥75μm).

Adjustable screen mesh for different soil types.

2. Desander & Desilter (Secondary Cleaning) Hydrocyclones (10-50μm separation) for finer solids.

GNZJ Series – Compact design for HDD rigs.

3. Decanter Centrifuge (Ultra-Fine Separation) GNLW Series – Recovers bentonite & removes colloidal solids (down to 2-5μm).

Variable Speed Control – Adjusts for different slurry densities.

4. Mud Mixing & Storage System Jet mixing hopper for fresh mud preparation.

Agitation tanks to maintain slurry consistency.

5. Cuttings Handling (Optional) Screw conveyor – Transports separated solids to disposal.

Vertical cuttings dryer (VCD) – Further reduces fluid on waste (for <5% moisture).

System Workflow
Used slurry returns from the borehole.

Shale shaker removes large cuttings.

Desander/desilter takes out medium-fine particles.

Centrifuge polishes mud for reuse.

Clean mud is pumped back into the system.

Solids are discharged for disposal.

Applications
Horizontal Directional Drilling (HDD)

Microtunneling & Pipe Jacking

Utility Installation (Fiber, Gas, Water Lines)

Geothermal Loop Drilling

GN Solids Control Co., Ltd. is a Chinese company specializing in the design, manufacturing, and service of solid control systems and related equipment for the oil and gas drilling industry.

Oil sludge is a hazardous byproduct of drilling, tank cleaning, and refinery operations, containing oil, water, and solid particles. GN Solids Control provides advanced oil sludge treatment systems to recover oil, reduce waste, and meet environmental regulations.

GN Oil Sludge Treatment Process GN’s system typically includes mechanical separation, thermal treatment, and chemical conditioning for maximum oil recovery.

1. Pretreatment (Sludge Screening & Heating) Screw Pump/Grit Separator → Removes large debris.

Heating System (optional) → Lowers viscosity for better separation.

2. Primary Separation (3-Phase Decanter Centrifuge) GNLW Series Centrifuge separates:

Recovered Oil (reusable)

Water (can be treated further)

Solids (≤5% residual oil, safe for disposal)

3. Secondary Treatment (Thermal Desorption or Chemical Washing) Thermal Desorption Unit (TDU) → For heavy sludge, removes oil via heating (optional).

Chemical Demulsifiers → Enhances oil-water separation.

The inserted second pic tells “shale shaker”,

A shale shaker is a critical piece of solids control equipment used in drilling operations to remove large drill cuttings (rock fragments) from drilling fluid (mud). It is the first and most important stage in the solids separation process, ensuring efficient drilling performance and fluid reuse.

The inserted first pic tells “mud cleaner”,

A mud cleaner is a crucial solids control device used in drilling operations to remove fine drill cuttings (+25 microns) and low-gravity solids (LGS) from drilling fluid (mud). It combines hydrocyclones (desanders & desilters) and a fine-mesh shaker screen to enhance solids removal efficiency.
