A long-time client of IFM was having difficulty meeting NPDQES regulations caused by their high effluent CBOD levels. These levels were able reach upwards of 200 mg/L with a permit level of 25 mg/L. Their single-celled lagoon WWTP and biannual discharge rate quickly encouraged anaerobic conditions to take hold. These circumstances are what caused a large increase in odor of the water source and the high CBOD levels.
An SDOX® Supersaturated dissolved oxygen injection system was used to facilitate the diffusion of large quantities of O2 through the bulk water source. The unit effectively reduced the CBOD to a level below EPA regulations. IFM continues to treat this single celled lagoon twice a year, prior to discharging, with the SDOX® unit.
