Abstract
Med oppfinnelsen tilveiebringes en sammensetning for fjerning av fosfationinnholdet fra vann. Sammensetningen ifølge oppfinnelsen inneholder 0,1 til 99,9 vektdeler av en jernforbindelse, nærmere bestemt ett eller flere faste vannholdige Fe(II)- eller Fe(III)-salter eller de oksiderte former derav, oppmalt tørt sammen med 99,9 til 0,1 vektdeler av et porøst aluminiumsilikat inneholdende utbyttbare ioner og O, l til l O mol av en kalsiumionkilde, nærmere bestemt kalsiumkarbonat sammen med enten kalsiumoksid eller kalsiumkarbonat eller begge, pr. ett mol jernforbindelse. Med oppfinnelsen tilveiebringes det også en fremgangsmåte for fremstilling og anvendelse av den ovennevnte sammensetning.The invention provides a composition for removing the phosphate content from water. The composition of the invention contains 0.1 to 99.9 parts by weight of an iron compound, in particular one or more solid aqueous Fe (II) or Fe (III) salts or the oxidized forms thereof, milled dry together with 99.9 to 0 1 parts by weight of a porous aluminum silicate containing exchangeable ions and 0.1 to 10 moles of a calcium ion source, more specifically calcium carbonate together with either calcium oxide or calcium carbonate or both, per one mole of iron compound. The invention also provides a process for the preparation and use of the above composition.
