Abstract
To restore the filtering properties of kieselguhr, which has been used, for example, in the treatment of sugar liquors, it is agitated in a boiling solution of hydrochloric or other mineral acid, the mixture being then separated in a filter and the cake formed washed with hot water and dried by means of steam while still in the filter. In a modified process the acid is separated from the kieselguhr by decantation, the kieselguhr being passed with wash-water into the filter.ALSO:To restore the filtering properties of kieselguhr, which has been used, for example, in the treatment of sugar liquors, it is agitated in a boiling solution of hydrochloric or other mineral acid, the mixture being then separated in a filter and the cake formed washed with hot water and dried by means of steam while still in the filter.
