GN Solids Control recently delivered a complete Modular Hydrovac Slurry Dewatering System to an overseas client for efficient handling and treatment of hydrovac slurry generated during excavation activities. This system is specifically designed to separate solids and recover reusable water, reducing disposal volume and environmental impact.

Complete Modular Configuration
The delivered system is composed of five integrated modules, each engineered for a specific separation stage to ensure optimal dewatering performance:
🔹 Coarse Screening Module (GNLMP-1536)
The process starts with a coarse screen unit that removes large-size debris such as rocks, wood and heavy trash from incoming slurry. This step significantly reduces the burden on downstream equipment and helps maintain steady flow.
🔹 Double Deck Fine Shaker Module (GNZS596K)
Next, the slurry passes through a high-capacity double-deck shale shaker designed to remove fine solids efficiently. The dual-layer screen design maximizes throughput while maintaining effective solid-liquid separation.
🔹 Desilter Module (GNZJ594J-8N)
Equipped with multiple 4-inch hydrocyclones, this unit targets the removal of particles in the 20–40 micron range. The desilter is essential for reducing solids loading before entering the centrifuge stage.
🔹 Decanter Centrifuge Module (GNLW553D-VFD)
This high-speed VFD-controlled centrifuge performs precision separation of ultra-fine solids. With a large 22-inch bowl, the GNLW553D is ideal for heavy-duty slurry treatment and can handle high volumes while delivering excellent clarity of recovered water.
🔹 20-ft Chemical Dosing System
To improve the separation efficiency of fine and ultra-fine solids, GN Solids Control integrates a fully automated flocculant preparation and dosing unit. This module ensures stable and accurate polymer mixing and dosing, enhancing the dewatering process.

Benefits and Application
The modular design provides several advantages:
✅ Scalable & Flexible Setup – Each unit is built into standard-sized frames or containers, enabling easy transportation, on-site installation, and customization according to client needs.
✅ Efficient Dewatering – The system effectively reduces slurry volume and recovers clean water for reuse or safe discharge.
✅ Environmental Compliance – Helps clients meet environmental regulations by minimizing waste disposal and preventing pollution.
✅ Cost Savings – Reduced transportation and disposal costs through on-site treatment and fluid recycling.

As industrial and environmental regulations tighten, efficient oil sludge treatment has become a critical challenge for oil and gas companies. GN Solids Control, a global leader in solids-liquid separation technology, offers a highly effective Oil Sludge Treatment System designed to recover valuable oil, recycle water, and minimize solid waste. Our solution is widely used in oilfields, refineries, tank cleaning operations, and drilling waste management, ensuring a sustainable approach to sludge disposal.

The Working Process of GN Oil Sludge Treatment System
Our GN Oil Sludge Treatment System follows a structured, multi-stage separation process to extract oil, purify water, and manage solids efficiently:

Pre-Treatment & Chemical Washing – The sludge is first heated to 60-70°C, and chemical agents are introduced to break the oil-water-solid emulsion, making separation easier and more effective.
Solids Separation – The mixture then passes through a settling tank with an inclined plate clarifier, which allows larger solid particles to settle, reducing the burden on downstream separation equipment.
Three-Phase Decanter Centrifuge Separation – A high-speed decanter centrifuge is used to effectively separate the sludge into three distinct phases: recovered oil, clean water, and solid waste.
Final Treatment & Disposal – The recovered oil is clean enough for reuse or sale, the water can be recycled for further processing, and the solids, which contain less than 2% oil content, can be safely disposed of or treated further using biodegradation or thermal desorption.

Key Advantages of GN Oil Sludge Treatment System
High Separation Efficiency – Achieves an optimal separation of oil, water, and solids, maximizing oil recovery and minimizing waste.
Modular and Customizable Design – Configurable based on different sludge compositions and processing capacities, making it suitable for various industries.
