Abstract

This study assessed the use of pilot- and commercial-scale ammonia stripping systems within the context of a proposed sequential manure treatment system of anaerobic digestion, coarse fiber separation, fine solids separation, and ammonia stripping. The study results point to the need for additional work to support the development and implementation of ammonia stripping as a viable nutrient recovery technology for dairies. However, it may be the case that ammonia stripping, with its focus on nitrogen removal, may be most likely to be adopted in poultry facilities than on dairies because of the susceptibility of anaerobic digestion of poultry litter to ammonia inhibition.
