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 slurry tanker during application with the purpose of reducing ammonia emission, later called “field acidification”. Another effect of the sulfuric acid was the addition of sulphate to slurry. Following a successful research evaluation, the system was developed by BioCover to a pilot scale system for tests and following used in commercial slurry application. The commercial product was named SyreN. Today 120 SyreN units are operative in Denmark, acidifying approx. 5.350.000 m3 slurry/year, and do so with an acid amount that often corresponds with the sulphur need by the crops.
