MLSS - Sludge Interface

MLSS stands for Mixed Liquor Suspended Solids, and it is also referred to as the concentration of activated sludge solids (i.e., sludge concentration). In wastewater treatment processes, there is a method for purifying water quality using microorganisms, and the aggregation of these microorganisms is called activated sludge. The concentration of activated sludge is managed to determine whether it is in a desirable state for wastewater treatment. The sludge interface refers to the boundary between the settled sludge in the treatment tank (i.e., sedimentation tank) and the supernatant. By managing factors such as the depth of the interface and its thickness, it serves as an indicator for withdrawing sludge to prevent the outflow (carryover) of settled sludge, ensuring proper treatment.
