  • Acidification of slurry in barns, stores and during application: review of Danish research, trials and experience

    Abstract Acidification is recognised as a method for reduction of ammonia volatilisation of manure. During the last two to three years acidification of slurry has become common in Denmark. In 2012 it has been estimated that about 11 % of all applied slurry in Denmark was acidified, and in 2013 it is expected that up to 20 % will be acidified. In all cases sulphuric acid is used for ...

  • Experiences with 7 years of acidification in Denmark - SyreN system, a commercial method to fertilize with sulphate while reducing animal slurry ammonia emission

    Abstract In 2009 a group of companies were assembled (Aarhus University, SEGES, BioCover A/S and Grundfos ) and committed to a joint development project “SyreN” - technology for field acidification of slurry, with support from the Danish ministry for development and innovation. The group defined and created a demand specification for using sulfuric acid together with a ...

  • Ammonia sanitization of blackwater for safe use as fertilizer

    Source-separated blackwater from low-flush toilets contains plant-available nutrients and can be used as a fertilizer. The aim of the study was to evaluate the impact on pathogen inactivation when treating blackwater with urea and/or lime. Blackwater was spiked with Salmonella typhimurium, Escherichia coli O157, Enterococcus faecalis, and Ascaris ...

  • In-situ comparison of phosphorus losses between organic and inorganic fertilizers

    Phosphorus (P) is one of the limiting factors of eutrophication. P added to soil from fertilizer application could pose a threat to water quality. According to agricultural habits, swine manure (SM), oil cake (OC), biogas slurry (BS), commercial organic fertilizer (OF) and compound fertilizer (CF) were selected to compare their P losses on a slope-land under natural rainfall. The results showed ...

  • Phosphorus distribution in untreated and composted solid fractions from slurry separation

    Received for publication May 7, 2009. The distribution of phosphorus (P) (water-soluble inorganic P [Pi], acid-soluble Pi, and residual P) was determined in 40 samples of solids from solid–liquid separated slurry. These were collected from separation plants using different technologies, separating by simple mechanical means, by flocculation as pre-treatment before mechanical separation or by ...

  • Poultry Food Short

    This facility processes, seasons, cooks, and flash-freezes poultry products and wanted to increase their production. The existing wastewater system could not meet the discharge requirements to the local POTW (city) and more stringent limits were imposed as a condition of their expansion. The facility was looking at a tremendous capital improvement cost to increase the size of their wastewater ...
