Purpose of research: Experimental development

The subject of this project reaches from the optimisation of system technology for an efficient intense separation of solid material from fresh slurry to a fully functional separator with a broad range of applications. By optimising the existing technology and upgrading it, the systems efficiency and its marketability can be improved significantly. This makes it possible to process existing nutrition surplusses in slurry and fermentation residues into fertilisers cost-effectively and energy-efficiently. Due to the transportability gerenrated this way, these products can be transported into further distant regions and be used as needed there. Due to the necessary finer working mechanics, the separation of coarser substrates is not readily possible. Therefore the upstream extension of a deliberately coarse separating technology is implemented in this project. After a preselection of possible Separators trials for the integration of this coarse separation into the existing system module will be carried out for this purpose. With this extension the overall module will therefore be able to perform results that are competetive with significantly more complex technologies at lower expense for maintenence and upkeep, investment costs and energy demand. The trials with the separation base module also showed a stronger tendency of filtrate sedimentation. The precise filtration's particular separation results allow the follow-up treatment method by means of filtrate sedimentation in the first place, which was not possible before due to the systems slower sedimentation. In order to integrate a highly efficient lamella separator laboratory experiments and prototype trials will also be planned and carried out.
