Manure storage and field application

DANETV offers verification of technologies and products for storage of manure and digested biomass from biogas plants. Examples are monitoring systems for slurry tanks to reduce the risk of leakages and pollution of lakes and streams. In addition it could be technologies for treatment of manure and digested biomass during storage in order to reduce ammonia emission. AgroTech performs verifications of such technologies.

Completed verifications:

Reduction of ammonia emission from field application of slurry
A slurry acidification system developed by Harsø Maskiner A/S has been verified. The system is used for addition of acid to slurry in storage tanks under controlled conditions. The aim is to lower the pH of the slurry thereby reducing the ammonia emission during field application of slurry. The verification was done for both pig slurry and cattle slurry. Verification Statement, Verification Report and Test Report.

Online monitoring of slurry storage tanks
The Danish company PlusTec has developed an electronic monitoring system for slurry storage tanks, LevelTec. In case of leakage or overflow the LevelTec-system is generating a SMS-alarm message, which is sent to the owner or employees at the farm. Thereby, immediate action can be taken to stop the slurry release and to avoid or minimize pollution of nearby streams or lakes. LevelTec can also be used for improved management and planning of slurry application and distribution on the different fields. DANETV has undertaken a verification to document that LevelTec is functioning as claimed and that an alarm is actually generated and received when it is supposed to. In addition, it has been verified that LevelTec is robust and reliable under typical environmental conditions for places where the system is normally installed.  Statement of verification, Verification report and Test report.

Reduction of odour from application of slurry on fields
A verification has been undertaken for the product SyreN, which is a new technology for slurry application on fields. Additives are mixed into the slurry during application in order to reduce emissions of both ammonia and odour. The main purpose of the DANETV-test is to verify the size of the odour reduction. The verification task was undertaken for the company Biocover, which has developed SyreN. Verification Statement, Verification Report and Test Report.
