IWC 23-76: Upgrading of Lagoon Treatment to Meet New Ammonia Limits using MBBR
Chandler Johnson, World Water Works, Inc., Oklahoma City, OK USA; Scott Langner, DemKota Beef, Aberdeen, SD
A slaughter house in South Dakota needed upgrade its lagoon treatment system to meet new effluent ammonia limits of < 20 mg/L. A new single-stage closed top MBBR followed by DAF for solids separation was chosen since its capable of treating wide ranges of loadings, operate under wide temperature ranges with a consistent effluent quality in a small footprint. Within 8 weeks after start-up, the system was under the effluent limit.
