[Sludge Digestion.] The liquid separates readily from the solids which begin to settle to the bottom. (...) A layer of liquid, the digester overflow or supernatant forms above the solids, and this layer has only a small amount of suspended solids. (...) In all probability a scum layer consisting of hair, match sticks, undigested grease and other material will form at the top. This scum layer is very objectionable (...) 1, record 1, English, - scum%20layer

Tailings slurry from the extraction plant contain water, residual bitumen, sand, silt and clay, and solvent. The slurry is pumped into large settling basins or ponds, where the coarse sand quickly separates from the fine clays and silts. The silts and clays settle out to form a layer which consolidates very slowly. When this layer reaches 30 percent solids by weight ..., it is called "mature fine tails". 1, record 3, English, - mature%20fine%20tail
