As an important centrifugal separation equipment, the decanter centrifuge is indispensable in the wastewater treatment process and plays a vital role in the wastewater treatment process. Its efficient operation is based on the use of centrifugal force to separate liquid from solid. By pushing the denser particles against the wall of the rotating bowl while causing the lighter liquid part to move to the center, the decanter centrifuge can effectively separate large amounts of slurry containing liquid and solid particles. This makes it the best method for wastewater treatment. The decanter centrifuge uses centrifugal force to effectively separate large amounts of slurry, which makes it the best method for wastewater treatment.
Gain a complete understanding of the decanter centrifuge by first delving into its function. When handling various industrial endeavors, the combination of solids and liquids can frequently result in the formation of sludge, ultimately posing a threat to water sources.
Currently, some water plants are still using outdated methods to treat surface water and groundwater for residential use. In addition to providing clean water, the presence of excess sludge solution is also a major problem. Disadvantages of traditional technology include:
- Pollutes the environment
- Not suitable for large-scale processing
- Long time consumption
Decanters use innovative new technology and do have many benefits that are worth the expense.
What is a Decanter?
Decanters separate liquids from solids and are an important part of the following operations:
- Gas and oil drilling
- Manufacturing
- Oil recovery
- Wastewater treatment facilities
- Dredging
In wastewater treatment, the functions of the decanter centrifuge are as follows:
Inlet Pipe
Inlet pipe – Liquid (slurry) containing solid particles flows through the decanter centrifuge through the inlet pipe.
Speed Increase
The slurry enters a bowl that rotates at high speed. As the bowl rotates, centrifugal force causes the heavier solid particles to be drawn toward the walls of the bowl. The solids form a layer while the liquid flows toward the center of the bowl.
Discharge
Liquids leave the centrifuge through a separate outlet ready for disposal or further processing. The screw conveyor pushes the solids near the tapered end of the centrifuge. The conveyor, also called a screw conveyor, has a speed that helps move the solids to the discharge.
Efficient solid-liquid separation capability
The horizontal centrifuge uses the centrifugal force field through the high-speed rotating drum and rotary conveyor to effectively separate solid particles from liquid in the wastewater. This separation method is not only highly efficient, but also capable of processing suspensions containing solids with a particle size greater than 0.005mm and a concentration range of 2-40%, which is suitable for a variety of wastewater treatment scenarios.
Advantages of Decanter Centrifuge Compared with Other Machines
Decanter water treatment works continuously and automatically. It does not need to stop between pressing batches like plate and frame machines. This helps to increase productivity, save energy and reduce operating costs.
The self-contained, compact design reduces the required installation space compared to other feasible processes. Stainless steel materials make it durable.
Save water and easy to clean.
Decanter can process a variety of sludge juices, including sludge containing metals and chemicals. The sludge after pressing has stability and high dryness.
Decanter is easy to install and quick to start and shut down.
This tool has a larger production capacity compared to small machines. This also reduces the number of units required.
The equipment is easy to optimize and operate because it has a few key variables and reliable feedback information.
Due to the low labor cost of decanter compared to other processes, it requires less operator attention and continuous maintenance.
Compared to other processes such as belt filtration process, decanter has higher performance and flexibility.
Significant environmental benefits
The application of decanter centrifuge in wastewater treatment can significantly reduce the solid content in wastewater and reduce the sludge volume, thus reducing subsequent treatment costs and transportation costs. At the same time, the moisture content of the sludge after decanter centrifuge treatment is significantly reduced, which facilitates subsequent resource utilization or harmless treatment, and helps achieve the goals of resource utilization, reduction, and harmless treatment of wastewater.
Widely used in various industries
The application range of decanter centrifuge in wastewater treatment is wide, covering chemical, light industry, pharmaceutical, food, environmental protection and other industries. Whether it is metallurgical wastewater, textile wastewater, papermaking wastewater, leather wastewater, pesticide wastewater, etc., the decanter centrifuge can play its efficient solid-liquid separation role and help various industries achieve wastewater discharge standards.
