Membrane technology is a promising candidate for producing mineral fertilizers from animal slurry. This paper presents a combination of membrane technologies for processing digested slurry, lists retentions of nitrogen (N), phosphorus (P) and potassium (K) and evaluates the economic and technological potential of the processes presented. To increase the content of plant nutrients in mineral concentrates substantially, improved RO (reverse osmosis) or additional technology is required.
