What Does PSS Stand For?
PSS stands for Primary Sewage Sludge
PSS, or Primary Sewage Sludge, refers to the solid waste material that is generated during the preliminary treatment of sewage in wastewater treatment plants. This sludge primarily consists of organic matter, microorganisms, and inorganic materials, and it is a byproduct of the sedimentation process where heavier solids settle at the bottom of treatment tanks. PSS plays a critical role in the overall wastewater treatment process and is subject to further processing for effective disposal or resource recovery.
