high density thickener

Underflow from a HighRate Thickener will have a yield stress of 1030 Pa and look like tomato ketchup while underflow from a HighDensity Thickener will have a yield stress of 30100 Pa and resemble molasses The Paste Thickener underflow will have a yield stress of 200250 Pa and look like toothpaste How to select a Thickener
