PATENT-ANSPRUCH : EMI2.2 chemische Zusätze und Filter aus Kanalwässern von Städten, Schlachthofabwässern in Kanalsystemen und Klärbecken gewonnenen Schlammassen, darin bestehend, dass man dieselben mit einer zur Herbeiführung einer Filtrationsfähigkeit nötigen Menge Schwefeloder Salzsäure versetzt, erwärmt, durch Filterpressen oder ähnliche Vorrichtungen die abgeschiedenen festen Massen von ihrem Wasser befreit und nun entweder direkt oder unch einigem Vortrocknen in geeigneten Apparaten mit fett1ösenden, flüchtigen Stoffen behandelt, wobei das gewonnene Fett zur Seifen-, Stearinsäure-, Oleinsäure-Bereitung ce. Verwendung finden kann, während die entfettete Masse als Dünger oder nach Absiebung des feinen Staubes zur Papier-und Pappefabrikation benutzt wird. EMI2.3 PATENT CLAIM: EMI2.2 Chemical additives and filters from sewer water from cities, slaughterhouse wastewater in sewer systems and clarification basins, consisting of adding an amount of sulfuric or hydrochloric acid necessary to bring about a filtration capacity, heating them, and removing the separated solid masses from their water by filter presses or similar devices and then either directly or without some pre-drying in suitable apparatus, treated with fat-dissolving, volatile substances, the fat obtained for the preparation of soap, stearic acid, oleic acid. Can be used, while the defatted mass is used as fertilizer or after filtering the fine dust for paper and cardboard production. EMI2.3
