What is Sludge Dewatering?

Sludge dewatering separates sludge into liquid and solid components for waste minimization. There are various technologies for sludge dewatering, including plate & frame and belt filter presses, centrifuging, and geomembranes. In addition to these, there are other options available.

It is important to note that dewatering is not intended to treat the sludge or liquid, it only separates the solid and liquid components so that it is easier and more cost-effective to handle the separate phases for final disposal. Once the sludge has been dewatered, both the solid and liquid components may contain contaminates that will need to be treated separately.

Why is Dewatering Necessary?

The purpose of sludge dewatering is for waste minimization and to achieve overall cost efficiency for disposal. Additionally it can also help with a company’s sustainability objectives. Generally both the public and private sectors are required to dispose of sludge in a manner that is approved by regulatory agencies and are in line with their own organizational requirements and environmentally safe.

Sludge dewatering is typically focused on reducing the weight and volume of the sludge so that disposal costs - including transportation - are kept to a minimum. Water removal is the primary means of volume reduction before sludge waste can be treated or disposed of in the most economical manner.

Choosing the Optimal Technology

The choice of a sludge treatment method is dependent on several factors including the characteristics, volume, timing and the available disposal options.

When searching for dewatering services, it is important to look for a partner who can offer a comprehensive suite of dewatering services and apply the right technology for your specific issues to provide the most cost effective solution.
