In this research project the Klass spiral filter was tested for the purpose of separating manure and fermentation residues. The main focus was on the relief of the area through a high degree of separation of nutrients, such as phosphorus and the achievable biogas yield from separated pig manure. For this purpose, a comprehensive series of studies with scientific support was carried out. In the first step, manure with different settings was separated on an agricultural pig fattening farm with the aim of a maximum phosphorus separation. In addition, fermentation tests were carried out to determine the possible biogas yield of the separated phases and compare it with the raw manure.
