January 1, 1972By J.C. Burns
Swine (Sus scrofa domesticus ) production in confinement requires economical and environmentally safe waste management systems. Anaerobic lagoons require periodic removal of effluent for land...
Aeration with ORP [oxidation-reduction potentials] control to suppress odors emitted from liquid swine manure systems
January 1, 1971
An oxidation ditch, a method of extended aeration, was adapted to hog confinement systems to stabilize the manure in the pits beneath the animals (Day et al. 1969). The oxidation ditch adds enough...
