Filter press dewatering is a common sludge treatment method that utilizes mechanical equipment to dewater sludge. In a filter press, the sludge is placed in a filter cloth and pressure is applied to squeeze out the water, resulting in a significant reduction in the sludge's moisture content. This technique is applicable to all types of sludge and is highly efficient in reducing the volume and increasing the consistency of the sludge for subsequent treatment or disposal. Users of this dataset need to account for regional variations in sludge characteristics and treatment regulations when applying this data to life cycle assessments. It is important to note the upstream treatment processes, as well as any post-dewatering treatment and final sludge disposal or usage pathways. Ensure that system boundaries are clearly defined to avoid double-counting or omitting impacts particularly when considering potential energy recovery from biogas production or nutrient recycling.
