PROCESS FOR PREPARING AN ADSORBENT FOR PHOSPHATE IN AQUEOUS MEDIUM
It relates to a process forproducing an adsorbent for adsorbing phosphate from aqueous medium comprising polynuclear iron (III) oxy-hydroxidestabilized by at least one constituent that inhibits ageing of the iron (III) oxy-hydroxidewhich is based on carrying out the desalinization step process by ta...

| description | It relates to a process forproducing an adsorbent for adsorbing phosphate from aqueous medium comprising polynuclear iron (III) oxy-hydroxidestabilized by at least one constituent that inhibits ageing of the iron (III) oxy-hydroxidewhich is based on carrying out the desalinization step process by tangential-flow filtration using tubular filtration membranesto remove salts from the system in the permeate and where the retentate is recirculated to the feed tank. Recirculation of the retentate improves salt separation effectiveness.
L'invention concerne un processus de production d'un adsorbant pour l'adsorption de phosphate à partir d'un milieu aqueux comprenant du fer polynucléaire (III) oxy-hydrodéstabilisé par au moins un constituant qui inhibe le vieillissement du fer (III) oxy-hydroxidelequel est basé sur la mise en œuvre du processus de l'étape de dessalement par filtration tangentielle à l'aide d'une membrane de filtration tubulaire pour éliminer les sels du système dans le perméat et où le rétentat est remis en circulation dans le réservoir d'alimentation. La recirculation du rétentat améliore l'efficacité de séparation de sel. |
