Application of Hydrothermal Carbonization, Membrane Distillation, and Algae Cultivation for Sustainable Dairy Manure Treatment
Dairy production has grown more efficient as the number of cows on each facility increases; however, this expansion has also increased the concentration of localized manure that can lead to environmental concerns such as greenhouse gas emissions or eutrophication. This dissertation investigates a …

Microwave-based Pretreatment, Pathogen Fate and Microbial Population in a Dairy Manure Treatment System
… precipitation are two effective ways of treating dairy manure for recovering biogas and phosphorus. Anaerobic digestion of dairy manure is commonly limited by slow fiber degradation, while one of the limitations to struvite precipitation is the availability of orthophosphate. The aim of this work …

Comparison of Dairy Manure Anaerobic Digestion Performance in Gas-lift and Bubble Column Digesters
… one of the most promising management options for dairy manure treatment. Manure wastewater from dairy farms has been used for methane production for decades. However, performance failure due to inadequate mixing is routine. In general, the mixng of anaerobic digester is achived throguh mechnical …

Optimization of Biological Nitrogen Removal From Fermented Dairy Manure Using Low Levels of Dissolved Oxygen
… ammonia nitrogen (TAN) from solids-separated dairy manure. An anaerobic fermenter, upstream of the N removal reactor, produced volatile fatty acids (VFAs), to be used as an electron donor to fuel denitrification, and TAN at a COD:N ratio of 18:1. However, sufficient amounts of non-VFA COD was …
