Sludge Filter vs Sludge Dewatering: What's the Real Difference?

Sludge Filter versus Sludge Dewatering: Is There a Difference?

Sludge treatment might seem to be a rather complex process, but you know what — once we divide it into several steps, it's really not that difficult to grasp the idea. Sewage forms sludge, which is a thick cover of mud when goes via a wastewater plant. But that sludge has to be processed before it can be safely disposed of or reused. This is where sludge treatment processes like sludge filter and sludge dewatering are partial remedies.

Basics of Primary Sludge Treatment Processes

There are sludge filter by which we can make liquid separated from the solid particles after passing through a network. Sludge dewatering meanwhile removes the water from sludge, allowing this to be easier to handle and dispose of.

The Efficiency and Effectiveness of Sludge Filter VS Sludge Dewatering

In terms of efficiency, both sludge filter and sludge dewatering are advantageous. The most significant indication of the sludge filter press machine is to clear the solids from this sludge which will happen in ordering an additional dry end product. Nevertheless, while this process does not have the potential for significant volume reduction like incineration, it still is more effective at decreasing sludge volume to make transportation and disposal of sludge easier and less costly.

Sludge Filter And Sludge Dewatering: Two Standard Ways To Process Sludge. 

There are distinct differences in the equipment and methodologies used between sludge filter, and dewatering systems. Traditional sludge filter systems usually contained the appropriation of a filter press or centrifuge to isolate the liquid and solid fractions in slurry. Sludge dewatering is the process of sludge thickening and reducing its volume by removing as much of the water content from it as possible, while still maintaining room for a proper waste-water management method like belt presses or screw presses.

In term of cost, sludge filter systems are typically more expensive up-front given the capital equipment involved. However, they can be more cost effective in the long-term in terms of running costs. While Sludge dewatering system on the other hand cost lower with initial installation but can demand more maintenance over time. Now, the trade-off is environment-wise: Both ways have their advantages and disadvantages in this respect. A sludge filter system can give you a drier end product, which means that the material you would need to dispose of is less. On the downside, sludge dewatering systems may cost more to run in terms of energy used during operation.

Which Type of Sludge Treatment Is Best for You?

When choosing a suitable strategy for the treatment of sludge at your plant known, it is important to consider limiting factors such as are the volume of waste sludge, and legal constraints on the environment. In the end, the selection between sludge filter and sludge dewatering will come down to your unique requirements and preferences.
