In the laboratory, the material from each core retained on the 250-[micro]m mesh was elutriated in supersaturated sucrose solution to remove juvenile macrofauna and sediments were sorted to remove larger macrofauna.
Organic matter in samples, including invertebrates and salamanders, was elutriated from the inorganic substrate, passed through nested 1-mm and 250-[micro]m sieves, and preserved in a 6-8% formalin solution containing Phloxine B dye to facilitate sorting.
The amounts of conditioner used average about two percent ferric chloride and ten percent lime, on a dry solids basis, for plain settled or chemically precipitated sludge; four percent ferric chloride and eight percent lime for digested sludge; two to three percent ferric chloride for elutriated digested solids, and four percent of ferric chloride only for activated sludge.
No additional process water is required until the pulp reaches the elutriated retention area
The same procedure is repeated a second time using elutriated bone ash instead of sifted ash.
Freshwater was added to a sample, and the sample was mixed so that sediments settled to the bottom and the elutriated organisms floated to the surface.
The surficial 2 cm and the deeper 3-5 cm organic matter were elutriated separately from the sediment, poured through a 1-mm sieve, collected on a Gelman AlE filter, dried, and ground.
Samples were elutriated in the laboratory and sieved through 90-[micro]m mesh to retain the smallest individual clams and to calculate abundance (measured as clams per square meter) for each sampling period and location.
Removed substrata were placed into buckets of filtered (250 [[micro]meter]) water, repeatedly elutriated, and the water poured through 250-[[micro]meter] mesh nets.
The water in each compartment was filtered, substrates removed, and invertebrates elutriated from the substrates.
The amounts of conditioner used average about two percent ferric chloride and ten percent lime, on a dry solids basis, for plain settled or chemically precipitated sludge; four percent ferric chloride and eight percent lime for digested sludges; two to three percent ferric chloride for elutriated digested solids, and four percent of ferric chloride only for activated sludge.
