Clarifier (sedimentation basin)

(Environmental Engineering) A tank in which quiescent settling occurs, allowing solid particles suspended in the water to agglomerate and settle to the bottom of the tank. The solids resulting from the settling being removed as a sludge.

Biochemical oxygen demand (BOD)

(Environmental Engineering) The amount of oxygen required to oxidize any organic matter present in a water during a specified period of time, usually 5 days. It is an indirect measure of the amount of organic matter present in a water.

Brinell Hardness Test

(english) A common standard method of measuring the hardness of materials. The smooth surface of the metal is subjected to indentation by a hardened steel ball under pressure. The diameter of the indentation, in the material surface, is then measured by a microscope and the hardness value is read from a chart or determined by a prescribed formula.

Blue Annealing

(english) Heating hot rolled ferrous sheet in an open furnace to a temperature within the transformation range and then cooling in air, in order to soften the metal. The formation of a bluish oxide on the surface is incidental.

Dry Rodded Weight

(Concrete Engineering) The weight of dry aggregate rodded into a cylindrical container of diameter approximately equal to the height, each of 3 layers rodded 25 times, and the excess aggregate struck off level with the top of the container

Strength:

(english) A very general term that may be applied to a material or a structure. In a material, strength refers to a level of stress at which there is a significant change in the state of the material, e.g., yielding or rupture. In a structure, strength refers to a level of level of loading which produces a significant change in the state of the structure, e.g., inelastic deformations, buckling, or collapse.

Mixed liquor volatile suspended solids (MLVSS)

(Environmental Engineering) The volatile suspended solids concentration in the activated sludge tank.

Jacking Equipment

(Concrete Engineering) In prestress concrete, the device used to stress the tendons.

Mixed liquor suspended solids (MLSS)

(Environmental Engineering) The total suspended solids concentration in the activated sludge tank.

Stability:

(english) Stability is best defined as the opposite of instability, which is the occurrence of large structural deformations which are not the result of material failure.

Discrete settling

(Environmental Engineering) Settling in which individual particles settle independently, neither agglomerating or interfering with the settling of the other particles present. This occurs in waters with a low concentration of particles.
