Overview: A North Carolina company seeks to minimize pumping frequency and expense for solids removal from hog lagoons.
Solution: Install MBD Aeration based on lagoon volume. Systems tested have an average sludge reduction from 5’ to 3.5’ over a 60 day period. Electrical cost to reduce BOD from 400 feeder pigs in this test is about $2.50 per day, or $0.04 per pound of waste reduced or less than $0.01 per gallon of sludge. In addition, odor is reduced.
