Effect of Nitrification on Phosphorus dissolving in a Piggery Effluent treated by a Sequencing Batch Reactor
Posted in: Environment by admin on | No Comments
Trials using modified sequencing batch reactors were performed to study the influence of the amount of nitrified nitrogen on pH (and thus solubility of the phosphorus) and determine whether the pH was the main cause of the increased phosphorus dissolving. It was determined that the modified sequencing batch reactor process management (hydraulic retention time and anaerobic/aerobic step duration) did allow the control of the amount of nitrogen nitrified in one cycle and hence the amount of the phosphorus dissolved.

Natural crusting of slurry storage as an abatement measure for ammonia emissions on dairy farms
Posted in: Environment by admin on | No Comments
Observations provided information on the impact of a range of factors on the potential for crust
formation. The most important factors were slurry solids content (crusting increasing with
dry matter (DM) content), volume:surface area ratio of the storage (influencing nature of
the crust and rate of formation), livestock diet (crusting more likely with grass silage),
slurry management (agitation). Of particular importance, were weather conditions with
evaporation increasing crusts and rainfall having the opposite effect.
