www3.epa.govPhosphorus removal is also less effective than in facultative lagoons because of more stable pH and alkalinity conditions. 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.
