Le d\u00e9fi<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Le Moyen-Orient est l'une des r\u00e9gions les plus difficiles au monde pour le dessalement de l'eau de mer. La salinit\u00e9 \u00e9lev\u00e9e et les mati\u00e8res organiques pr\u00e9sentes dans l'eau d'alimentation limitent l'enveloppe de conception pour un flux et une r\u00e9cup\u00e9ration \u00e9lev\u00e9s dans les syst\u00e8mes d'osmose inverse.<\/p>

\u00a0<\/p>

SAWACO est le principal fournisseur d'eau potable municipale et industrielle du Royaume d'Arabie saoudite. La soci\u00e9t\u00e9 a connu une demande d'eau sans pr\u00e9c\u00e9dent, mais n'a pas \u00e9t\u00e9 en mesure d'augmenter la capacit\u00e9 de production de son usine de dessalement de Store City en raison de contraintes li\u00e9es \u00e0 la prise d'eau de mer et aux capacit\u00e9s d'\u00e9vacuation de la saumure. Une production suppl\u00e9mentaire d'eau douce \u00e9tait n\u00e9cessaire dans un d\u00e9lai court de moins de 6 mois.<\/p>

\u00a0<\/p>

Face au manque d'options pour augmenter la capacit\u00e9 et au co\u00fbt \u00e9lev\u00e9, en temps et en argent, de la construction de nouvelles infrastructures d'admission et de d\u00e9charge, Gradiant avait la solution.<\/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\t<\/div>\n\t\t<\/section>\n\t\t\t\t

La solution<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Pour r\u00e9soudre ce probl\u00e8me, SAWACO s'est tourn\u00e9 vers Gradiant, qui a effectu\u00e9 une d\u00e9monstration \u00e0 long terme de la technologie RO Infinity CFRO \u00e0 l'usine de Jeddah Corniche Sud de SAWACO. Le processus RO Infinity CFRO de Gradiant fonctionne en appliquant de l'eau saline au c\u00f4t\u00e9 perm\u00e9at de la membrane, r\u00e9duisant ainsi la diff\u00e9rence de pression osmotique et permettant le dessalement de flux \u00e0 forte salinit\u00e9 \u00e0 une pression relativement faible. Tous ces proc\u00e9d\u00e9s utilisent des membranes et des \u00e9quipements d'osmose inverse standard, disponibles dans le commerce.<\/p>

\u00a0<\/p>

Le proc\u00e9d\u00e9 RO Infinity a \u00e9t\u00e9 valid\u00e9 dans le cadre d'une d\u00e9monstration prolong\u00e9e de 3 ans chez SAWACO, afin de prouver un fonctionnement continu avec une disponibilit\u00e9 du syst\u00e8me de 99,8%, une r\u00e9cup\u00e9ration de 50%, tout en utilisant moins d'\u00e9nergie que les technologies concurrentes.<\/p>

\u00a0<\/p>

Le succ\u00e8s de la d\u00e9monstration de RO Infinity a conduit \u00e0 l'attribution d'un contrat \u00e0 grande \u00e9chelle. Gradiant concevra et livrera un nouveau syst\u00e8me de concentration de saumure utilisant la technologie RO Infinity, qui s'int\u00e9grera dans l'empreinte de l'usine de dessalement d'eau de mer conventionnelle existante de SAWACO \u00e0 Store City. SAWACO, avec l'aide de Suido Kiko Middle East, construira l'ensemble de l'installation. Le syst\u00e8me de Gradiant ne sera aliment\u00e9 que par de la saumure, rien d'autre, \u00e0 75 000 mg\/L de TDS, provenant de l'usine de dessalement conventionnelle existante - l'eau qui aurait autrement \u00e9t\u00e9 gaspill\u00e9e sera transform\u00e9e en un nouveau perm\u00e9at de haute qualit\u00e9. La concentration finale en TDS de la saumure sera de 150 000 mg\/L.<\/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\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Les avantages<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

The combined new Gradiant RO Infinity brine concentration system and existing conventional SWRO desalination facility will have an overall recovery rate of 80% – which nearly doubles current production, without increasing the feedwater or pretreatment requirements. Further, there will be reduced brine concentrate flows that would require discharge and disposal.<\/p>\n

\u00a0<\/p>\n

Outre les \u00e9conomies de co\u00fbts d'investissement \u00e9vit\u00e9es, puisqu'aucune nouvelle infrastructure ne sera n\u00e9cessaire, la solution de Gradiant permettra \u00e0 SAWACO de r\u00e9aliser d'importantes \u00e9conomies en termes de co\u00fbts d'exploitation et de co\u00fbts totaux de l'eau. La consommation d'\u00e9nergie sp\u00e9cifique de la technologie RO Infinity est une fraction de celle de la concentration de la saumure \u00e0 l'aide de technologies thermiques conventionnelles.<\/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\t<\/div>\n\t\t<\/section>\n\t\t\t\t
