แปลว่า(Environmental Engineering) A device which uses an electric field to trap particulate pollutants.
Total suspended solids
แปลว่า(Environmental Engineering) (TSS) is the amount of suspended (filterable) matter in a water.
Reactive waste
แปลว่า(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.
Secured landfill
แปลว่า(Environmental Engineering) A landfill which has containment measures such as liners and a leachate collection system so that materials placed in the landfill will not migrate into the surrounding soil, air and water.
Corrosive waste
แปลว่า(Environmental Engineering) A waste that is outside the pH range of 2 to 12.5 or a waste that corrodes steel at a rate greater than 6.35 mm (0.25 in) per year. One of EPA's four hazardous waste properties.
Coagulation
แปลว่า(Environmental Engineering) Particle destabilization to enhance agglomeration.
Clarifier (sedimentation basin)
แปลว่า(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.
Hydrocarbon
แปลว่า(Environmental Engineering) Any organic compound composed entirely of carbon and hydrogen. Two examples are methane gas and octane.
Chemical fixation (or stabilization/solidification)
แปลว่า(Environmental Engineering) A term for several different methods of chemically immobilizing hazardous materials into a cement, plastic, or other matrix.
Deoxygenation
แปลว่า(Environmental Engineering) The consumption of oxygen by the different aquatic organisms as they oxidized materials in the aquatic environment.
Composting
แปลว่า(Environmental Engineering) The controlled aerobic degradation of organic wastes into a material which can be used for landscaping, landfill cover, or soil conditioning.
Respiration
แปลว่า(Environmental Engineering) Energy production in which oxygen is the terminal electron acceptor, i.e. oxidation to produce energy where oxygen is the oxidizing agent. See fermentation.
