Dewatering is the process of removing excess groundwater from a site where construction or work is conducted. This is necessary because there is a specific level of groundwater that needs to be present at a site where work is conducted. When the water level exceeds a specific level of groundwater, it becomes detrimental to the environment, workers on the site, and the results of the work being conducted.
It is essential to understand that there are different dewatering techniques. Some function independently to deliver qualitative results, while some function in conjunction with others for outstanding results. The dewatering techniques that function independently include open-ditch pumping, WellPoint Systems, and more, while techniques that function with other dewatering techniques include the sludge dewatering and similar methods.
This article will focus on the sludge dewatering technique, highlighting what it is, how it works, and its benefits. Please ensure to read to the end for more exciting information.
What Is Sludge Dewatering?
Sludge dewatering is a dewatering service where water is extracted from a site, and sludge cakes are formed in the process. Sludge cakes are solid deposits formed when dewatering an area. These deposits can be contaminants that are harmful to the site and affect the work conducted.
How Does Sludge Dewatering Work?
This process involves extracting sludge from the groundwater present on a site where construction is conducted. It can be described as the process of purifying a site from contaminants. It is conducted using diverse techniques, and they include:
- Centrifuge: This involves using a centrifuge that spins the extracted water at high speed, forcing the solid deposits to settle, separating the two substances of different densities.
- Belt filter press: This technique uses a belt filter press to extract sludge cake from extracted water from a site. The sludge cake extracted in this technique will still have some water contents. However, it is suitable when dealing with a large case of sludge dewatering.
- Screw press filter: Similar to the belt filter press, this is convenient for large cases of sludge dewatering but produces a drier sludge cake. This press spins the extracted water at a low speed while expelling the uncontaminated water and retaining the sludge cake.
Benefits Of Sludge Dewatering
These benefits highlight how unique sludge dewatering is compared to other dewatering services or techniques. These benefits include:
- Waste volume reduction: By extracting sludge cakes from the slurry sludge water extracted from a site, this dewatering reduces the volume of the waste deposit from the site. This makes it easier to dispose of the waste extracted from a site.
- Lowers risks of spilling: When waste is still in a semi-liquid state, it increases the risk of spilling and contaminating the environment, especially during transportation. However, sludge dewatering reduces this risk because drier waste is obtained and transported.
- Waste recycling: The two products from sludge dewatering can be recycled and reused. The sludge cake gotten can be used as fuel, while the extracted water can be treated and reused.
- Environmental friendly: Reducing the sludge cake from a site to a more compact and drier form allows for an eco-friendly disposal method.
