Abstract

PURPOSE: To eliminate the irritating odor like that of NH3 and an amine from the titled waste, and to impart a taste resembling the stock of a fish or shellfish to the waste, by saturating the waste with carbon dioxide, adjusting the pH to a given range with a mineral acid, and by electrodialyzing the waste with an ion exchange membrane.
CONSTITUTION: Steffen's waste with the total solid content of 5W10% (pH about 13) is saturated with CO2 to pH about 10, concentrated to B× about 25W45°, and then adjusted to pH 4W10 with a mineral acid. The treated waste is then electrodialyzed with an ion exchange membrane, and preferably concentrated in a vacuum evaporator to B×60W80°. The precipitate formed in the saturation with CO2 is removed to give a treated solution comprising about 30% an ash, about 70% an organic substance, 15W20% an amino acid and 10W15% betaine. The waste after electrodialysis is concentrated to the betaine content 1.5W2.0 times and the amino acid content about 1.2W1.5 times those of the waste after CO2 saturation per the solid content. The concentrate formed on the electrodialysis concentration side is rich in potassium, and can be utilized as a potassic fertilizer.
