At GN Separation, we pride ourselves on providing cutting-edge solutions for liquid and solid separation across various industries. One of our flagship products, the Slant Plate Clarifier, also known as an inclined plate clarifier, exemplifies our commitment to efficiency and innovation.

What is a Slant Plate Clarifier?

The Slant Plate Clarifier is a specialized piece of equipment designed to separate solids from liquids with remarkable efficiency. When a mixture of solids and liquid—whether flocculated or not—enters the clarifier, it flows upward through a series of inclined plates. The solids naturally settle on the plate surfaces and slide down into a sludge collection hopper due to gravity. Meanwhile, the clarified liquid passes through orifice holes at the top, exiting the system as clean effluent.

Why Choose GN Separation’s Slant Plate Clarifier?

Our Slant Plate Clarifiers offer several advantages over traditional settling tanks and even more complex equipment like decanter centrifuges. These include:

• Compact Design with Large Effective Settling Area: The inclined plates provide a large effective settling area within a relatively small footprint. This design is not only space-saving but also enhances the separation efficiency.
• Energy Efficiency: Unlike more complex machinery, our Slant Plate Clarifier consumes minimal energy, making it a cost-effective solution for continuous operation.
• Easy Maintenance: With no moving parts except for an auger to transfer sludge, the clarifier requires minimal maintenance, reducing downtime and operational costs.
• Versatility in Operation: The system can function effectively with or without chemical dosing, depending on the specific needs of the application.

Technical Specifications

Our Slant Plate Clarifiers come in various models to suit different operational needs, ranging from the GNIPC-07B with a max flow of 7 m³/h to the GNIPC-273B, which can handle up to 273 m³/h. The models are designed with different inlet and outlet sizes, sludge volumes, and overall dimensions to cater to specific industry requirements.

Handling oily sludge is a critical challenge for many industries, including oil refineries, drilling operations, and industrial cleaning processes. GN Separation‘s Oily Sludge Treatment System offers a comprehensive solution designed to efficiently process and manage oily sludge, turning it into valuable resources and minimizing environmental impact.

Complete Oily Sludge Treatment Process

GN Separation’s Oily Sludge Treatment System is engineered to handle the entire treatment process of oily sludge, providing users with a robust and reliable solution. Our system encompasses several key stages:

1. Sludge Extraction
   Oily sludge is initially extracted from the sludge pit using GN’s solid vacuum pump or an excavator. This step is crucial for gathering the sludge for further treatment.
2. Heating & Conditioning
   The extracted sludge is then transferred to a pre-mixing tank where it undergoes stirring, pre-mixing, and conditioning. This heating process prepares the sludge for effective separation.
3. Coarse Particle Screening
   Following heating and conditioning, the sludge is treated using a vibrating screen to separate coarse particles. This ensures that larger debris is removed before further processing.
4. Secondary Heating & Conditioning
   The finer particles undergo a secondary conditioning process with the addition of chemical agents. This step strips the oil from the solid phase, allowing it to enter the liquid phase.
5. Solid-Liquid Separation
   The conditioned sludge is then pumped to a two-phase decanter centrifuge. This equipment separates the solid sludge from the liquid, with the resulting solid sludge having less than 2% oil content. This solid can then be further processed or biodegraded.
6. Three-Phase Separation
   Finally, the separated liquid is treated in a three-phase disc separator. This stage separates the oil into a saleable product, extracts usable washing water, and discharges the remaining solid through a flushing pump.

Applications in Various Industries

GN Separation’s Oily Sludge Treatment System is versatile and applicable in various scenarios:

• Oil Refineries: Efficiently manages and processes oily sludge generated during refining operations, reducing waste and recovering valuable resources.
• Drilling Operations: Treats drilling oily sludge, helping to manage waste and ensure compliance with environmental regulations.
• Oil Tank Cleaning: Handles sludge from oil tank cleaning processes, making it easier to dispose of or recycle the waste.
• Industrial Oily Sludge: Provides a comprehensive solution for industrial processes that produce oily sludge, improving waste management and recovery.

Customized Solutions for Your Needs

At GN Separation, we understand that each application is unique. That’s why we offer customized solutions tailored to the specific needs of our customers. By analyzing the characteristics of your oily sludge, we can provide a solution that maximizes efficiency and effectiveness.

At GN Separation, we take pride in our advanced Chemical Dosing Unit, a critical component of our GN Dewatering System. This sophisticated unit, along with our high-speed dewatering centrifuge, provides an efficient solution for separating fine particles in wastewater, addressing challenges that simple mechanical separation methods cannot overcome.

The Role of Chemical Dosing in Wastewater Treatment

In the wastewater treatment process, separating ultrafine particles is a significant challenge. While mechanical separation can handle particles between 2-5 microns, finer particles require a more advanced approach. This is where our GN Chemical Dosing Unit comes into play. By working in tandem with a high-speed decanter centrifuge, it can effectively separate ultrafine particles, meeting stringent separation requirements.
