Abstract
1. A process for the treatment of acid waste water containing aluminum and iron, wherein (a) the acid waste containing small amounts of colloidal silicic acid is heated to just below boiling point so as to precipitate aluminum hydroxide and hydrated iron (III) oxide and is neutralized with calcium oxide and/or calcium hydroxide ; (b) the resultant aluminum hydroxide iron (III) hydroxide precipitate is trated with sodium hydroxide until dissolution of the aluminum hydroxide as aluminate ; (c) the remaining hydrated iron (III) oxide precipitate is separated from the sodium aluminate solution, washed dried and the hydrated iron (III) oxide is pelletised for use as a gas-purifying medium or is converted by thermal treatment into iron (III) oxide suitable for use as pigment ; (d) and the sodium aluminate solution is converted into a crystalline zeolite by reaction with a water glass solution.
