for diamond core drilling waste water treatment project. GNLW223D-FHD hydraulic centrifuge system for the solid-liquid separation of coring drilling mud. It can operate without an electrical power supply, using a diesel engine to supply power, and a hydraulic driven centrifuge and feeding pump to carry out drilling mud treatment, prepare drilling mud, recover drilling fluid, reduce drilling waste, and meet environmental protection requirements.
2. One set of GNLW363D-VFD variable speed decanter centrifuge for oil drilling solids control system, it is a high-performance variable-frequency-drive decanter centrifuge. The VFD technology allows operators to adjust the bowl speed and differential speed in real time, optimizing separation efficiency according to changing drilling fluid properties and solids load.

Key features:
• High rotational speed and G-force for fine solids removal (down to 2–5 microns).
• Energy-efficient VFD control reduces power consumption and extends component life.
• Seamlessly integrates into standard oil drilling solids control systems as a second- or third-stage cleaning device.
• Enhances barite recovery and lowers overall mud costs.
3. One set of shale shaker GNZS593K and one set of GNLW363D high speed decanter centrifuge for HDD trenchless mud recycling system.

GNZS593K shale shaker features a large screening area (three panels) and high G-force exciter design. It removes coarse drill cuttings and large solids as the primary separation stage, ensuring that only fine particles are passed to the centrifuge.
GNLW363D decanter centrifuge – Acting as the secondary or polishing stage, this high speed decanter centrifuge removes ultra fine solids (down to 2–5 microns), allowing the recycled mud to maintain proper rheology and density for extended re-use.

GN Containerized Oil Sludge Treatment Plant for Africa Client

GN Solids Control has successfully supplied a fully containerized oil sludge treatment system to an African client. This compact, skid-mounted plant is designed to treat oily waste from crude oil tank cleaning, refinery ponds, and drilling operations. The system enables the recovery of valuable oil, recycles water, and significantly reduces solid waste volume—all while meeting stringent environmental standards.
The entire plant is integrated into standard shipping containers, making it ideal for Africa’s infrastructure conditions where ease of transport, rapid deployment, and relocation between sites are critical. The modular design also allows future expansion and simplified maintenance.

The system consists of four core modules:
(1) Pre-Mixing Tank Module
The pre-mixing tank module is the first step in the treatment process. Raw oil sludge often has high viscosity, high solids content, and poor fluidity. This module heats, dilutes, and conditions the sludge to create a homogeneous slurry suitable for downstream separation.

(2) Shale shaker Module
After pre mixing, the sludge still contains large debris, stones, and coarse sand. If these particles enter the centrifuge directly, they will cause accelerated wear and reduce separation efficiency. The vibrating screen module removes these oversized solids as a protective step.
(3) Three Phase Decanter Centrifuge Module
Including three phase decanter centrifuge, its feeding pump, fluids catching tank and skid. This is the core separation unit of the entire plant. The three phase decanter centrifuge simultaneously separates oil, water, and solids from the conditioned sludge using high centrifugal force. It is particularly suitable for oily sludge with wide fluctuations in oil content and complex compositions.

(4) Chemical Dosing Module
Effective chemical treatment is essential for breaking emulsions and enhancing separation efficiency. The chemical dosing module automatically prepares and injects flocculants, coagulants, and demulsifiers into the process stream.

Two Package Drilling rig Solids Control Equipment for Middle East Client

Recently two package of drilling rig solids control equipments are shipping to Middle east client. The equipments list including:

1. 6 sets of drilling fluids shale shaker
As the first phase of solids control, these high-performance shakers are engineered to remove large cuttings and debris from the drilling fluid. With high G-force output and large screen areas, these six units ensure that the client can maintain high circulation rates while efficiently separating solids, protecting downstream equipment from abrasive wear.
2. 2 sets of drilling fluids mud cleaner
Positioned downstream from the shakers, these mud cleaners combine desanders and desilters in a compact unit. They are critical for removing fine sand and silt particles (15-74 microns). By integrating hydrocyclones with a fine-mesh shaker screen, these two units will allow the client to significantly reduce dilution rates and lower overall mud costs.

3. 4 sets of drilling fluids decanter centrifuge
For fine and ultra-fine solids separation, the four decanter centrifuges represent the pinnacle of the system. Operating at variable speeds, these centrifuges will recover barite, remove colloidal solids, and ensure that the drilling fluid maintains the precise density and viscosity required for challenging Middle Eastern formations. GN decanter centrifuge has been widely used for drilling mud cleaning, drilling cuttings treatment, oil sludge cleaning and other industrial waste water solids liquid separation.
Shale shaker, mud cleaner and decanter centrifuge is the major solids control equipments for drilling rig solids control system. Except for these equipments, we also produce vacuum degasser, shaker screens, centrifugal degasser, desander, desilter, mud agitator, mud gun, mixing hopper, vertical cuttings dryer, drilling waste decanter centrifuge, high G drying shaker, mud tanks and complete set of oil sludge treatment system, drilling waste management system, dewatering unit.
