The treatment of sludge, liquid manure and fermentation residues from biogas production, comprises supplying the sludge, the liquid manure, and the residues into a fine sieve vacuum separator, manufacturing and collecting a filtrate and a separated solid, supplying the filtrate into a vibration shearing force filter, and manufacturing and collecting a primary permeate and a primary retentate. The separator consists a vertical-lifting coil, cylinder enclosing the coil that exhibits sieve sections with a mesh size of 30-300 mu m, and the cylinder surrounds a low-pressure housing. The treatment of sludge, liquid manure, and fermentation residues from biogas production, comprises supplying the sludge, the liquid manure, and the residues into fine sieve vacuum separator, manufacturing and collecting a filtrate and a separated solid, supplying the filtrate into a vibration shearing force filter, and manufacturing and collecting a primary permeate and a primary retentate. The separator consists a vertical-lifting coil, cylinder enclosing the coil that exhibits sieve sections with a mesh size of 30-300 mu m, and the cylinder surrounds a low-pressure housing. The filtrate is supplied into a further fine sieve vacuum separator before the supply of the filtrate into a vibration shearing force filter. The further fine sieve vacuum separator exhibits sieve sections with a smaller mesh size than the first vacuum separator. The primary permeate from the shearing force filter is subjected to a reverse osmosis. The filtrate and/or the permeate are acidified. The separated solid is used as a soil conditioner, fertilizer, fuel, fermented substrate, mineral fertilizer, cellulose filler and a component of the same or used for the production of the same. The produced retentate is used as fertilizer, and/or processed as a commercial fertilizer. The produced permeate is used as operating water in a biogas facility, cleaning or cooling water or agricultural production water and/or supplied in a receiving stream, brook, watercourse or canalization. An independent claim is included for a device for carrying out the treatment of sludge, liquid manure and fermentation residues from biogas production. |
