USPTO Abstract
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.
