Lesson 11: Sludge Thickening Objective
Sludge thickening calculations. Reading Assignment Read the online lecture. Lecture Sludge Thickening ... Thickening is usually accomplished in a tank called a gravity thickener. A thickener can reduce the total volume of sludge to less than half the original volume. An alternative to gravity thickening is dissolved air flotation.
