Abstract

The invention provides a composition for removing the phosphate ion content of waters. The composition of the invention contains 0.1 to 99.9 parts by mass of an iron compound, namely one or more solid hydrous Fe(II) of Fe(III) salts or the oxidized thereof, ground together with 99.9 to 0.1 parts by mass of a porous aluminium silicate containing exchangeable ions and 0.1 to 10 moles of a calcium ion source, namely calcium hydroxide, calcium oxide and/or calcium carbonate per one mole of iron compound. The invention, furthermore, provides processes for use production and use of the above-mentioned composition.
