dnr.wi.govBNR is the biological reduction of nitrogen and/or phosphorus in the final effluent using microorganisms. (Standard Method 5210B) The cBOD test is used to measure the oxygen demand of carbonaceous organic material in a wastewater sample as cBOD (mg/L). This test includes the use of a nitrogenous demand inhibitor to exclude the oxygen demand of

ipcbee.comThe general purpose of phosphorus removal from wastewater is to eliminate excess phosphorus content discharge to receiving waters and then utilize this excluded phosphorus load in the way which is the most proper for the natural phosphorus cycle in nature. Usually, phosphorus is present in wastewater in soluble form.
What is Phosphorus?
www.ohiowea.orgPhosphorus occurs naturally at low levels in water, plants, and animals. Phosphorus occurs unnaturally in fertilizers (used in agriculture), cleaners (used in industry) and wastewater (from household sewage). Phosphorus is found in water, solids (detritus), and in the bodies of biological organisms.

Phosphorus removals of about 15 to 25 percent can be expected with aerated lagoons. Removal of coliforms and fecal coliforms can be effective, depending on detention time and temperature.
