Sludge Treatment
Transportation—Thickening—Dewatering
The sludge produced by various mechanical, biological, and physicochemical treatments is the primary waste generated in wastewater treatment plants.
According to some studies, approximately 20-45 kg per equivalent inhabitant can be produced per year. The volume of sludge produced can vary depending on the characteristics of the water being treated, the processes used, and the size of the treatment plant.
A key characteristic of the sludge to be treated is knowing its water content, as this indicates the sludge’s properties and the costs associated with transporting and disposing of it. The dry matter content can vary depending on the type of sludge and the method used for its handling.
One of our main concerns is the presence of heavy metals, as this is a factor limiting the reuse of sludge in agriculture. The EU has repeatedly pointed out that this disposal method, even when meeting legal limits, is not safe, as its use in agricultural land leads to the accumulation of heavy metals in the soil.
European landfill regulations set a maximum organic matter content of 5%, making the disposal of sludge in landfills increasingly unfeasible.
