| Use advice for data set | 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. |
| Technical purpose of product or process | The process data represents the dewatering of sludge from municipal wastewater treatment using a filter-press. This unit process is often employed in waste management systems to reduce the liquid content of sludge, thereby reducing weight and volume for more cost-effective transport and disposal. The treated sludge can subsequently be used for various applications such as landfill cover or soil amendment, depending on its composition and local regulations. |

| General comment on data set | 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. |

| Technology description including background system | The process of filter press dewatering involves placing the sludge on a filter cloth, applying pressure to squeeze water out of the sludge, separating the water from the solid particles in the sludge, and ultimately obtaining a dry sludge mass. |
