Several types of tray thickeners have been developed, classified according to the arrangement of feed and discharge in the various compartments. Probably the most generally applicable is the balanced-type tray thickener. In this each compartment has a separate feed and overflow, but the settled solids from all compartments are brought …

Four types of roux are classified by color and length of cooking time, from white to blonde and brown to black. Although a basic ratio for roux is equal parts fat and flour by weight, the extended cooking time for a dark roux reduces the flour's thickening power, so the ratio is adjusted up to three parts flour to two parts fat.

The sonar system was supplied with an automated scum cleaner, that operated every 5 minutes. The ORCA sonar transmitter provided two analog outputs. The first was the "bed level" output and the second was the "clarity" of the water (suspended solids) between the sonar transducer diaphragm and the bed level.

some systems, an infrared (light path) blanket detector is used to determine when the blanket starts to rise. In other systems, the pumps are on timers, and thickened solids are drawn off at regular intervals. Gravity thickeners are usually operated at collector tip speeds between 0.08-0.1 m/s (15 and 20 ft/min).
