Flocculant settling
แปลว่า(Environmental Engineering) Settling in which particle concentrations are sufficiently high that particle agglomeration occurs. This results in a reduction in the number of particles and an increase in average particle mass. As agglomeration occurs higher settling velocities result.
Denitrification
แปลว่า(Environmental Engineering) The anoxic biological conversion of nitrate to nitrogen gas. It occurs naturally in surface waters low in oxygen, and it can be engineered in wastewater treatment systems.
Sulfate Attack
แปลว่า(Concrete Engineering) Deleterious chemical and/or physical re-action between sulfates in ground water or soil and certain constituents in cement, which result in expansion and disruption of the concrete.
Plastic Consistency
แปลว่า(Concrete Engineering) Condition in which concrete, mortar, or cement paste will sustain deformation continuously in any direction without rupture.
Trace contaminants
แปลว่า(Environmental Engineering) Contamination found in trace (very low) levels.
Cybernetic
แปลว่า(Environmental Engineering) Systems which change in response to feedback.
Base Metal Contamination
