Les éléments environnementaux dans la gestion durable de l'eau : L'héritage d'Infilco Degremont
La gestion durable de l'eau nécessite une approche holistique, tenant compte non seulement des infrastructures physiques, mais aussi de l'interdépendance des éléments environnementaux. Cet article explore comment les fabricants d'équipements, comme l'ancienne division du traitement de l'eau d'Environmental Elements Corporation (EEC), ont contribué à cette approche, devenant finalement partie intégrante de l'héritage d'Infilco Degremont, Inc.
Environmental Elements étaient des éléments clés dans la gestion de l'eau, englobant :
- Source d'eau : Cet élément fait référence à l'origine de l'eau, qu'il s'agisse d'eau de surface comme les rivières et les lacs ou des sources d'eau souterraine. La qualité et la disponibilité de la source d'eau influencent fortement le processus de traitement de l'eau.
- Qualité de l'eau : Cela englobe les caractéristiques chimiques, physiques et biologiques de l'eau, y compris les contaminants, la température, la turbidité et le pH.
- Demande en eau : Ce facteur prend en compte le volume d'eau nécessaire à diverses utilisations, telles que les usages domestiques, industriels et agricoles.
- Écosystème : Cet élément reconnaît l'impact des pratiques de gestion de l'eau sur les écosystèmes environnants, y compris la vie aquatique, la biodiversité et les cycles de l'eau.
La division du traitement de l'eau d'EEC s'est spécialisée dans la conception et la fabrication d'équipements innovants pour le traitement de l'eau, répondant à divers éléments environnementaux. Leur gamme de produits comprenait :
- Systèmes de filtration : Pour éliminer les solides en suspension, les particules et autres contaminants de l'eau.
- Technologies de désinfection : Pour éliminer les micro-organismes nocifs par des méthodes telles que l'irradiation UV et la chloration.
- Systèmes de déchloration : Pour éliminer l'excès de chlore de l'eau, améliorant son goût et sa sécurité pour la consommation.
- Filtration membranaire : Pour la purification avancée de l'eau, éliminant les sels dissous, les molécules organiques et les bactéries.
- Systèmes d'osmose inverse : Pour produire de l'eau de haute qualité en éliminant les sels dissous et les impuretés.
L'acquisition de la division du traitement de l'eau d'EEC par Infilco Degremont en 2008 a réuni deux entreprises leaders dans le domaine. Cette acquisition a renforcé la position d'Infilco Degremont en tant que leader mondial des solutions de traitement de l'eau. L'expertise et la technologie combinées leur ont permis d'offrir une gamme complète de services, de la conception et de l'ingénierie à la construction et à l'exploitation des usines de traitement de l'eau.
Perspectives d'avenir :
L'héritage de la division du traitement de l'eau d'EEC continue de vivre à travers Infilco Degremont. Leurs produits innovants et leur expertise ont contribué au développement de pratiques durables de gestion de l'eau dans le monde entier. En comprenant et en traitant les éléments environnementaux par le biais de solutions intégrées, des entreprises comme Infilco Degremont font progresser un avenir où l'eau propre et potable est accessible à tous.

Exercise:
Scenario: A small town is experiencing water quality issues due to high levels of iron in the water supply. The town council has decided to invest in a water treatment system to address this problem.
Task: Based on the information provided about Environmental Elements Corporation (EEC) and their product line, suggest two specific technologies that could be used to effectively remove iron from the town's water supply. Explain why these technologies are suitable for this specific situation.
Exercice Correction
Two suitable technologies for removing iron from the town's water supply are: 1. **Filtration Systems:** Specifically, a **sand filter** or a **multi-media filter** could be effective in removing iron. These filters use layers of sand or other media to trap suspended particles, including iron. 2. **Oxidation and Filtration:** This process involves adding oxidizing chemicals like chlorine or potassium permanganate to the water, which converts dissolved iron into insoluble particles. This allows for the removal of iron through a subsequent filtration step, such as a **sand filter** or a **membrane filter**. These technologies are suitable for this specific situation because: * **Sand and multi-media filters** are effective at removing suspended iron particles. * **Oxidation and filtration** are efficient in removing dissolved iron by converting it into a form that can be easily filtered. By implementing these technologies, the town can effectively address the iron issue in their water supply, ensuring clean and safe drinking water for their residents.
