La technologie prim\u00e9e d'extraction s\u00e9lective des contaminants (SCE) de Gradiant est l'un des syst\u00e8mes de traitement les plus robustes et les plus fiables sur le march\u00e9 pour les eaux us\u00e9es industrielles et la r\u00e9utilisation de l'eau. La SCE est une m\u00e9thode de traitement \u00e0 plusieurs \u00e9tapes qui peut \u00eatre adapt\u00e9e \u00e0 vos besoins afin de cibler une vari\u00e9t\u00e9 de contaminants \u00e0 des charges variables. - tels que l'huile et la graisse, le sulfure d'hydrog\u00e8ne, les COV et les COV semi-volatils, et les ions sp\u00e9cifiques.<\/p>

La plateforme SCE int\u00e8gre diff\u00e9rentes technologies de traitement physique et chimique afin d'\u00e9liminer de mani\u00e8re strat\u00e9gique et efficace les contaminants cibl\u00e9s. La plateforme SCE est propos\u00e9e comme traitement autonome ou en compl\u00e9ment des plateformes ROI, CGE ou FRO pour le pr\u00e9traitement ou le post-traitement.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

Cristallisation en lit fluidis\u00e9 de Gradiant (FBC)<\/strong> est l'une des technologies brevet\u00e9es de Gradiant dans la plate-forme SCE. Le FBC r\u00e9cup\u00e8re des min\u00e9raux pr\u00e9cieux tout en \u00e9liminant une s\u00e9rie de contaminants, en utilisant des sables silicat\u00e9s comme mat\u00e9riau porteur. Les ions inorganiques sont \u00e9limin\u00e9s en formant des cristaux stables de sels m\u00e9talliques avec le sable porteur, qui eux-m\u00eames sont \u00e9limin\u00e9s afin de r\u00e9duire les d\u00e9chets . Le FBC est le plus souvent utilis\u00e9 pour l'\u00e9limination du calcium, du fluorure, de l'ammoniaque, du phosphate, du cuivre et du nickel.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
