The BOD bottle is a narrow mouth bottle with a ground glass stopper and a funnel rim around the seal. Before the bottle is put into the incubator, water is added to the funnel neck around the seal to insure that there is an air-free seal. The top of the bottle is often further covered with foil or plastic wrap to prevent evaporation from the water seal.

The use of acclimatized organisms is one of the major weaknesses in using BOD as a regulatory measurement parameter. When industrial effluents are sampled, and where those effluents contain biologically resistant or unusual compounds, it is virtually impossible to obtain an accurate BOD measurement because the "seed"organisms have not developed extracellular enzymes that will permit them to degrade the compounds in the industrial effluent. As a consequence, the BOD measurements will be disproportionately low and unrepresentative of the true strength of the waste system.

For air flows of around 1000ft3/gallon, in a 24ft tower, a comparison of 1:5redwood slats was made against plastic truss bars at South Lake Tahoe WWTP, and the redwood slats showed virtually 100% ammonia removal versus 75% for the truss bars. The truss bars never did reached the same level of effectiveness that the slats attained even for air flows up to 4000, the ammonia removal was only 90%. The reasons are somewhat obvious-surface area being a significant factor. See Slechta, Culp. JWPCF 1967, Vol. 39, No 5., pp. 787-814.

CEEP is a working group within the Central European Chemical Industry Council, located in Bruxellex, Belgium. Their publications have analyzed the character and performance of phosphate detergents and found that phosphates are not as harmful to the environment as was first thought, and that they are a very effective detergent builder, outperforming their substitutes. The other findings include the fact that phosphate detergents account for about 25% of the total P in the influent of the wastewater treatment plant (the balance is from human sources), and the overall volume of wastewater sludge generated when phosphates are used is significantly lower than when other forms of detergent substitutes are utilized.

Many of the current microfiltration systems are being installed with pore sizes of 0.4 microns. The definition of suspended solids uses a 0.45 micron filter so the TSS is zero. It is also important to remember that when modeling a process using the ASM models, the definition of soluble materials is anything that passes 0.2 micron.
