Biochemical Oxygen Demand (BOD)
By: Nathan Hathaway and Alison Arling Published: October 24, 2019 One of the principal concerns in America’s waterways is oxygen deprivation due to wastewater discharge from industrial facilities. If wastewater is not adequately treated before discharge, the remaining organic constituents can exert an oxygen demand on the receiving waterway. This oxygen demand can have widespread […]The Eight Growth Pressures of Wastewater Treatment: #1 BOD Loading
Industrial wastewater treatment involves physical, chemical, and biological approaches. Physical treatment removes suspended solids, settleable solids, and oils and grease. Chemical treatment is often required for effective or enhanced removes dissolved and colloidal solids, nutrients, heavy metals, and oils and grease. And biological treatment removes biodegradable organics and nutrients. For biological processes, EBS focuses on […]Running the Biochemical Oxygen Demand (BOD) Test
The biochemical oxygen demand (BOD) test is a measurement of the quantity of oxygen required by bacteria to biologically oxidize organic material under aerobic conditions. Biochemical oxygen demand (BOD) is usually expressed in mg/L but can also be expressed in lbs/day. The organic matter serves as food for the bacteria and the cell receives energy […]Subtleties of the Biochemical Oxygen Demand Test
Biochemical Oxygen Demand (BOD) is a procedure used to measure the biodegradable organic material in a given water sample. This is one of the most commonly permitted parameters due to the drastic negative effects BOD laden water can have on natural streams. Bacteria rapidly degrade organic material through the process of aerobic respiration; which in […]
