Abstract
Fremgangsmåte til fjerning av fosfor, som ortofosfat, fra en vannholdig strøm innbefattende å innføre i strømmen en effektiv mengde kalsiumioner som fortrinnsvis er gips- avledet, justere pH til 5-8, innføre strømmen i et reak- sjonskar hvor den bringes i kontakt med et svakt rørt sjikt av finpartikulær magnesiumoksid i en mengde som er tilstrekkelig til å feste det dannede kalsiumfosfatet, anvende en pH på 8-12 i strømmen som er i kontakt med magnesiumoksidet, og fjerne en strøm fra karet som er fosforfortynnet.A process for removing phosphorus, such as orthophosphate, from an aqueous stream including introducing into the stream an effective amount of calcium ions which is preferably gypsum-derived, adjusting the pH to 5-8, introducing the stream into a reaction vessel where it is contacted with a gently stirred layer of fine particulate magnesium oxide in an amount sufficient to adhere the calcium phosphate formed, apply a pH of 8-12 in the stream which contacts the magnesium oxide, and remove a stream from the vessel which is phosphorus diluted.
