Each control should be addressed in the planning or optimization of a solids thickening system. 5.1.1 Gravity Thickeners In gravity thickening, solids are concentrated by the gravity-induced settling and compaction. Gravity thickening of solids provides a two-fold benefit: concentration and flow equalization/storage. Gravity thickeners typically are

The present invention is directed to a method and apparatus for maintaining steady state conditions in a separator. Steady state is maintained by controlling mass flow rates of influent to, and underflow from the separator. Specifically, an influent specific gravity and flow rate signals are monitored by an influent mass flow controller.

An intelligent control strategy for thickening process

To solve these problems, thickener optimal control strategies including state feedback identifier and expert system are proposed below. First, the current state of the thickener, which includes rake torque, overflow turbidity, mud bed level and underflow solid mass fraction, is identified by the state feedback identifier.
