EC238 Lecture Notes - Lecture 10: Oxygen Saturation, Meat Packing Industry, Eutrophication
Document Summary
Degradable degrades or breaks into components parts within the water. Organic residuals that are attacked and broken down by bacteria in the stream. Degradable wastes will break down in water; process uses oxygen. All higher life forms in watercourses are aerobic; require oxygen for survival. Oxygen level can become low enough that even aerobic bacteria may die. Large amounts of degradable pollutants can consume enough oxygen to turn an aerobic stream into an anaerobic stream. Without oxygen, aquatic life forms will die. Controlling the waste load required monitoring the ambient conditions in the watercourse and monitoring the magnitude of emissions. Dissolved oxygen (do) measure used to monitor ambient conditions. Biochemical oxygen demand (bod) measure of oxygen demand placed on a stream by any particular volume of effluent lomoar cpsd| 5490467. The amount of dissolved oxygen in a body of water is a function of ambient conditions, stream flow and waste load.
