Extraction of nutritious materials from acidic sludge waste solids by adsorption |
摘要 |
Nutritious materials, including proteins, are separated from acidic waste-activated sludge in a process which comprises: (A) converting by physical means active bacteria in said sludge to an inactive form; (B) subjecting the acidic sludge to an adsorbent material which is capable of adsorbing said proteinaceous material in an uncharged state from said sludge; (C) extracting said proteinaceous material from said adsorbent material by contacting it with an alkaline material having a cationic species to form a mixture of said separated proteinaceous material and said alkaline material; and (D) separating said proteinaceous material from said cationic species and other cations by contacting said mixture with a cation exchange resin.
