To increase the strength and diminish the bulk of, as of a liquid or an ore; to intensify, by getting rid of useless material; to condense; as, to concentrate acid by evaporation; to concentrate by washing; -- opposed to dilute.

feed that is high in energy, low in fiber content, and highly digestible.

Material to be filtered. Also referred to as feed, influent, intake, liquor, mud, prefilt, pulp, slimes or sludge.

A feed high in digestible energy and low in fiber.

The undiluted form of a dilutable cleaning product.

A feed high in nitrogen-free-extract (NFE) and total digestible nutrients (TDN) and low in crude fiber (less than 18 percent). Included are cereal grains, soybean oil meal, cottonseed meal, and by-products of the milling industry such as corn gluten and wheat bran. A concentrate may be low or rich in protein.

A product that results from copper-bearing rocks being crushed, ground into a slurry, and processed by froth flotation so that copper-rich mineral particles are separated from “gangue” or waste particles. The process is designed to selectively upgrade copper sulfide minerals into a concentrated form that is suitable as a smelter or other process feed.

A product that is intended to be diluted with water.

A liquid dosage form that should be further diluted with food or liquid when administered.

Raw water (or liquid) that does not pass through the membrane barrier. The concentrate stream contains higher total dissolved solids or suspended solids than the feed stream.

In crossflow filtration, the portion of a feed stream which does not permeate the medium but retains and is increased in the amount of ions, organics, and other particles which are rejected by the medium.

A feed used with another to improve the nutritive balance of the total and intended to be further diluted and mixed to produce a supplement or a complete feed.
