Abstract
173,255. Hepburn, G. G. July 24, 1920. Liquids, purifying.-Water is softened by filtering it through a mass consisting of or containing insoluble or difficultly-soluble salts of alkali metals with humic or ulmic acids, so that similar insoluble salts of the alkaline-earths are formed, and remain in the filter, in which they can be regenerated into the salts of the alkali metals for further use. For example, a hard water is treated with raw peat or peat which has been treated with a solution of alkali salt, such as sodium chloride; alternatively, humic or ulmic acid substances are used in combination with quartz, sawdust, or other inert diluents. The peat may be enriched with these substances. Used peat is regenerated by treatment with a solution of an alkali salt, such as sodium or potassium chloride, the anion of which can form an easilv-soluble salt with the metal to which the hardness of the water is due. When humic or other peaty acid is used it is preferable to convert it into an alkali salt by means of caustic or other alkali such as caustic soda or sodium carbonate. According to the Provisional Specification. the peat may be treated with magnesium or aluminium salts to prevent it from discolouring the water, or with calcium hypochlorite, chlorine, or other bleaching-agent.
