  • Thickener an overview ScienceDirect Topics

    Since the surface area of the thickener is the main variable the mass flow through the system is considered a flux (the product of concentration and velocity) such as tonnes solids/m 2 /day. Frequently the inverse of this flux is used called unit area m 2 /tonnes solids/ day. This allows system properties to be described in a general
