GN Containerized Sludge Dewatering Package for Soil Remediation in Middle East

GN Solids Control recently developed a Containerized Sludge Dewatering System for a Middle East project, designed specifically for contaminated soil treatment and cleaning. This innovative system is fully integrated into a 40-foot fabricated container, ensuring easy transportation and quick on-site installation. All components are pre-assembled and connected in the container, minimizing the time and effort required for installation at the project site.

The system includes the following key equipment:

High-Speed Big Bowl Decanter Centrifuge (GNLW654-VFD): This centrifuge is designed for efficient dewatering of sludge. It is equipped with a Variable Frequency Drive (VFD), allowing precise control of the centrifuge’s speed to optimize solids separation and ensure high performance in the dewatering process.

Feeding Pump (GNG30-075C): The system uses a 7.5kW screw pump, which is typically used to feed a 14-inch centrifuge. However, since the dewatering treatment capacity is much smaller compared to mud treatment, this smaller pump is a more suitable fit for the system, providing the necessary flow rate for the sludge dewatering process.

Polymer Dosing Pump (GNG05-030C): A screw pump is used as the polymer dosing pump. This pump is responsible for adding the appropriate amount of polymer to the sludge, which aids in the coagulation and flocculation processes, allowing for more efficient solid-liquid separation during dewatering.

Slag Screw Conveyor (GNSC10B-7.5M): A screw conveyor is used to transfer the separated sludge (slag) from the centrifuge to the designated disposal or storage area, ensuring continuous operation without manual intervention.

The entire system is housed in a 40-foot container, which provides a compact and mobile solution for on-site sludge dewatering. The containerized design ensures that the equipment is easily transportable, and the pre-connected system significantly reduces installation time at the project site. This approach provides a turnkey solution for contaminated soil treatment and cleaning, offering a streamlined process and efficient operation.

This containerized sludge dewatering system from GN Solids Control is an ideal solution for projects requiring reliable, high-performance dewatering equipment in a compact and easily deployable format.

3 Sets GNTBM-360 Slurry Separation Plant for Overseas Pipe Jacking Project

Pipe jacking is a non-excavation construction technique used to cross sensitive areas such as roads, rivers, and buildings. During the construction process, lubricating slurry (bentonite-based or polymer-based) is injected to reduce friction, which generates wastewater containing solid particles. The solid content in the waste water typically ranges from 5% to 30%, depending on geological conditions such as clay, sand, gravel, or rock layers. The particle size can vary from fine clay particles to gravel larger than 50mm, and in complex geological conditions, large rock pieces may also be present. This waste water needs to be treated to minimize environmental impact.

Given the characteristics of the wastewater, a staged treatment process is required. The typical treatment flow includes: coarse screening shale shaker separation, further solid-liquid separation, and fine filtration/ centrifuge dewatering system which are optional based on the environmental regulations of each country.

Recently, GN Solids Control completed three GNTBM-360 Slurry Separation Plants for an overseas pipe jacking project. These three systems were designed specifically for the same client. The systems include a coarse screening shale shaker system and two-stage solid-liquid separation using desanders and desilter hydrau cyclones. In countries where wastewater discharge is not allowed, additional options like flocculation and dewatering centrifuge systems can be added to meet the regulatory requirements.
Horizontal slurry pumps were used to feed the desander and desilter hydrau cyclones.

The GNTBM-360 Slurry Separation Plant is designed to efficiently treat wastewater generated during pipe jacking operations. The system ensures the effective separation of solid particles from the slurry, allowing for the recycling of the treated water and minimizing the environmental impact of the project. By using advanced equipment such as desanders, desilters, and optional centrifuge systems, the system delivers reliable, high-performance waste treatment solutions for pipe jacking projects.

This tailored slurry separation system from GN Solids Control is an essential solution for ensuring environmental compliance and sustainability in sensitive construction projects that involve slurry-based operations.

3 Sets GNLW654-VFD Dewatering Centrifuge Package for North Africa Municipal Sludge Dewatering

In the field of municipal sewage treatment, efficient equipment and advanced technical solutions are essential. Recently, GN Solids Control’s three GNLW654-VFD sludge dewatering  centrifuge units were successfully applied to municipal sewage treatment projects in North African.

1. GNLW654-VFD dewatering  centrifuge: a sewage treatment solution with excellent performance

These three GNLW654-VFD dewatering centrifuges played a core role in the project. They adopt advanced design and manufacturing processes and have excellent dewatering performance. The GNLW654-VFD decanter centrifuge can quickly and effectively separate the water from the sludge, greatly reducing the water content of the sludge, and providing convenience for subsequent treatment and disposal.

The centrifuge is equipped with temperature and vibration sensors to monitor the operating status of the equipment in real time. The temperature sensor can detect whether the equipment is overheating in time to avoid damage to the equipment due to high temperature. The vibration sensor can detect the vibration of the equipment. Once abnormal vibration occurs, timely measures can be taken to adjust it to ensure the stable operation of the equipment. This intelligent monitoring system improves the reliability and safety of the equipment and reduces the probability of equipment failure.

In addition, the GNLW654-VFD dewatering centrifuge is also equipped with four variable frequency control cabinets, which control the main motor, auxiliary motor, slurry supply pump and dosing metering pump respectively. The variable frequency control technology can flexibly adjust the operating parameters of the equipment according to actual needs to achieve the purpose of energy saving and consumption reduction. At the same time, it can also improve the operating accuracy and stability of the equipment to ensure the stability and reliability of the sewage treatment effect.

2. 6500L flocculation dosing device: Provide strong support for sewage treatment

In this project, 1 set of 6500L flocculation dosing device is also equipped for the centrifuge dewatering treatment. The device comes with a screw dosing metering pump, which can accurately control the amount of flocculant added and improve the effect of sewage treatment.

The flocculation dosing device plays a key role in the sewage treatment process. It adds flocculants to make the tiny particles in the sludge condense into larger particles, which is convenient for the centrifuge to dewater. The 6500L large-capacity design can meet the large-scale sewage treatment needs of the project, while the screw dosing metering pump has the characteristics of accurate metering and stable operation, ensuring that the amount of flocculant added is always kept at the best state.

GN Solids Control has been committed to providing high-quality solid control equipment and sewage treatment solutions to customers around the world. The successful application in the municipal sewage treatment project in North African countries once again proves the technical strength and product quality of GN Solids Control.
