— If it is a tailings thickener, you are wasting water, which is unforgiveable in the desert. If it is a concentrate thickener, you . may be handing the filter operator a headache, which he may return with interest. If it is a C.C.D. thickener, you are only making trouble for yourself farther along the line.

Lamella thickeners are high rate thickeners that use a series of angled impact plates to increase settling rates. The problems for the clients thickener were: When the bed level came up to high and entered the plate region the efficiency of the thickener dropped. The bed would sometimes break up and flow over into the launders.

— Examples of installation points are the feed, underflow, overflow and inside the thickener tank. Flow meters are combined with density meters to calculate the mass flow in the underflow and feed of the thickener. Inside the tank, submerged ultrasonic probes are used for tank profiling, interface detection and measuring the bed level.
