Attached growth reactor

(Environmental Engineering) A reactor in which the microorganisms are attached to engineered surfaces within the reactor. Examples of attached growth reactors are the trickling filter and the rotating biological contactor. See suspended growth reactor.

Alkali-Aggregate Reaction

(Concrete Engineering) Older terminology for Alkali-Silica Reactivity (ASR).

Reversible reaction

(Environmental Engineering) A reaction in which the reactant(s) proceed to product(s), but the products react at an appreciable rate to reform reactant(s).

Suspended growth reactor

(Environmental Engineering) A reactor in which the microorganisms are suspended in the wastewater. Examples of suspended growth reactors are activated sludge reactors and anaerobic digesters. See attached growth reactor.

Elementary reaction

(Environmental Engineering) A reaction in which the rate expression corresponds to the stoichiometric equation.

Irreversible reaction

(Environmental Engineering) A reaction in which the reactant(s) proceed to product(s), but the products react at an appreciable rate to reform reactant(s).

ASR - Alkali-Silica Reactivity

(Concrete Engineering) The reaction of aggregates, which contain some form of silica or carbonates with sodium oxides or potassium oxides in cement, particularly in warm, moist climates or environments, causing expansion, cracking or popouts in concrete.

Reactive waste

(Environmental Engineering) A waste which; 1) reacts violently with water, 2) forms potentially explosive mixtures with water, 3) is normally unstable, 4) contains cyanide or sulfide in sufficient quantity to evolve toxic fumes at high or low pH, 5) is capable of exploding if heated under pressure, or 6) is an explosive compound listed in Department of Transportation (DoT) regulations. One of EPA's four hazardous waste properties.

Reaction:

(english) A reaction is a force exerted by a support on an object: sometimes called support reaction. Using this definition, a reaction is an external force.
