municipal wastewater treatment ; sludge ; Centrifuge dewatering
Use advice for data set Users of this dataset should consider the specificity of the dewatering process with regard to the type of sludge being treated and the local municipal wastewater treatment procedures and regulations. It is crucial to contextualize the data within the technological applicability of the given region and the actual performance of the centrifuge equipment. Additionally, users should pay attention to any potential changes in environmental impact when integrating this process with other stages of sludge treatment or disposal and should assess the data in relation to the specific goals of their life cycle assessment study.
Technical purpose of product or process This dataset describes the centrifuge dewatering unit process as part of municipal wastewater treatment, specifically for the treatment of sludge. This process is designed for the reduction of water content in the sludge, yielding a semi-solid cake suitable for further processing or disposal. It is a crucial step in the management of sewage sludge, typically leading to reduced volume and weight, which in turn eases handling and can lead to cost and environmental impact reduction in subsequent transport and processing stages.

  • ILCD: Unit processes / End-of-life treatment / Waste water treatment
General comment on data set Sludge centrifuge dewatering is a method of separating water from solid particles in sludge using high-speed rotary centrifuges and is commonly used in wastewater treatment plants and industrial sites. This technique effectively reduces the volume and water content of sludge and improves its consistency for subsequent treatment or disposal.

Technological representativeness
Technology description including background system The process of centrifuge dewatering consists of loading sludge into the centrifuge basket, starting the centrifuge so that the basket rotates at high speed, separating the water in the sludge from the solid particles by centrifugal force, and ultimately obtaining a drier sludge cake and excluded water.
