What is sludge dewatering? How is sludge dewatering beneficial?

Wastewater treatment has become a necessity for survival as the scarcity of water is on the rise and it could get worse in the near future. As humans are held responsible for contaminating the water resource and for risking the lives of future generations, procedures like sludge dewatering have become a common practice in almost all countries across the globe.

What is sludge dewatering?

Dewatering of sludges is the process of removing excess water from the sludge. Sludge is the byproduct of extracting slurry during the procedure of wastewater treatment. Sludge dewatering is usually done to make its disposal easier. With numerous processes like belt press, centrifuge/decanter, and filter press, dewatering of sludge can be done easily. According to studies, sludges contain a lot of water, making them heavier and costlier for disposal.

The sludges obtained during the wastewater treatment from industries and municipals are separated into liquid and solid components. The liquid or the treated water can be used again for industrial purposes. The sludges should either be disposed of properly or with the help of a biodigester it can be again made into a dry powder. Strict regulations are followed across the globe for the proper disposal of sludges.

What are the benefits of sludge dewatering?

  • Volume and cost reduction:

The primary reason for sludge disposal is to reduce its volume for easy disposal. Through sludge dewatering, the volume can be reduced considerably which will, in turn, reduce the cost for disposal as well.

  • Wastewater recycling:

The water obtained after the dewatering process can be used for different purposes other than drinking. It takes you one step closer to preserving the water resource for future generations.

  • Eco-friendly:

The entire process of wastewater treatment and sludge dewatering is environment-friendly. All the hazards and contaminants in the water are removed making it safe for use again. The sludge on the other hand acts as a conditioner for the soil making it more fertile.

There are different methods for dewatering sludges. But with the use of biodigester, the volume of the sludges can be reduced by 70 to 80% which helps in making it into a dry powder that can be used to increase the fertility of the soil. Emvees offers the unique Sludge Dewatering Units (SDU) with biodigester for effective treatment of wastewater. We aim to offer the best quality services available and to preserve the water resource for a better tomorrow.
