Examination of Water and Wastewater 22nd Edition, section 5210B (2011) for biochemical oxygen demand/ carbonaceous biochemical oxygen demand (BOD/CBOD). •Discuss questions and concerns regarding BOD/CBOD analyses. •Discuss upcoming4

Biochemical oxygen demand, or BOD, is a chemical procedure for determining the amount of dissolved oxygen needed by aerobic biological organisms in a body of water to break down organic material present in a given water sample at certain temperature over a

vials were cleaned to remove any fingerprint before measuring COD with HACH spectrophotometer DR2800. The dissolved oxygen (DO) meter was used for BOD measurement. 1 L of diluted water sample was prepared by adding 1 mL each of phosphate buffer

CBOD or Carbonaceous BOD represents the Biological Oxygen Demand (BOD) from organic compounds and oxidation of inorganic compounds such as ferrous iron and sulfide. Any BOD from nitrifying organisms, which consume oxygen in the nitrification process of converting ammonia to nitrate, is removed by adding a nitrification inhibitor.

Disposable Plastic Test Tubes. Manufactured from polypropylene for excellent chemical and thermal resistance. Corning™ Falcon™Round-Bottom Polypropylene Tubes are tested to withstand 3000 x g centrifugation. Constructed of optically clear polystyrene for easy viewing of sample.

Tubes and vials are supplied in a range of heights, diameters, wall thicknesses, bottom shapes (round or flat), rim and closure styles in capacities from a few microlitres up to 25mL. Closures can be simple stoppers, screw-tops, push-tops, snap-tops or crimp-tops.

Add 0.5 ml to each tube using a fresh pipet for each tube. Mix by pipet- ting the solution up and down several times. (e) Incubate tubes for 1 hour in 50 C water bath. If the H-antigen is present, flocculation/agglutination may occur in 5-10 minutes but wjll occur within 1 hour.

METHOD #: 410.1. Chemical Oxygen Demand (Titrimetric, Mid-Level) COD Chemical Oxygen Demand. 1.0 Scope and Application. 1.1 The Chemical Oxygen Demand (COD) method determines the quantity of oxygen required to oxidize the organic matter in a waste sample, under specific conditions of oxidizing agent, temperature, and time.
