Circular basin thickener Circuiar high capacity thickener... 

The circular class of high capacity thickener is similar in general form to a conventional circular basin thickener, but cylinder diameters are limited to between 4 and 18 m (see Figure 1.4). Units are constructed from steel and include a cylindrical top portion, an inverted cone bottom section and an angled rake system mounted on a central drive head. Suspension throughputs are limited to about 4000 m h"k...

Selection of Type of Thickener or Clarifier Selection of the type of unit thickener or clarifier depends primarily on the optimization of performance requirements, installation cost and operating cost. For example, the inclined-plate type of clarifier provides for less solids-holding capacity than a circular or rectangular clarifier, but at a lower installation cost. The high-density thickener maximizes underflow solids concentration, requiring a higher torque rating than conventional thickeners. 

Thickener, conventional with central mechanism, rubber-lined c/s tank, motor, drive, weirs, pumps and pump boxes for acid-leached mineral processing with some flocculant addition. FOB cost = 950000 for a surface area = 300 m with n = 0.48 for the range 70-2800. TM = 3.0. Factor conventional with some flocculant addition, X 1.00 high capacity via flocculant addition, X 1.25. 

Some by-products from the food industry contain high proportions of plant cell walls which can be used in human nutrition to produce "dietary fibre" or "functional fibre", i.e. compounds which can be used for their water-holding/binding properties, oil-binding capacity,... or as a source of polysaccharides such as pectins which are suitable after extraction, as gelling or thickening agents.
