AWI : Le héros méconnu du traitement de l'eau et de l'environnement
AWI, qui signifie "Injection d'Eau Activée", est une technologie souvent négligée mais pourtant cruciale pour les applications de traitement de l'eau et de l'environnement. Bien que le terme puisse paraître technique, son principe est simple : injecter de l'eau activée dans différents systèmes pour obtenir les résultats souhaités.
Comment fonctionne AWI ?
AWI consiste à utiliser de l'eau qui a été "activée" par un processus spécifique, généralement impliquant l'application d'électricité ou un traitement chimique. Cette activation modifie les propriétés de l'eau, améliorant sa capacité à :
- Oxydation des contaminants : L'eau activée peut décomposer les polluants comme les matières organiques, les pesticides et les métaux lourds.
- Neutralisation des odeurs : AWI combat efficacement les odeurs désagréables en oxydant les molécules à l'origine.
- Contrôle de la croissance microbienne : L'eau activée peut inhiber la croissance des bactéries, des algues et d'autres micro-organismes.
- Amélioration de la filtration : L'eau activée peut améliorer l'efficacité des processus de filtration en aidant à éliminer les particules fines.

AWI Exercise:
Task: Imagine you are a manager at a small farm. You are struggling with a recurring issue of algae growth in your irrigation pond. Explain how AWI could be a solution to this problem and why it might be preferable to traditional algaecides.
Exercice Correction
AWI could be a solution to the algae problem by effectively controlling microbial growth. Activated water can inhibit the growth of algae, potentially eliminating the need for chemical algaecides. This approach has several advantages:
- **Environmentally Friendly:** AWI uses a more natural process, minimizing the introduction of harsh chemicals into the pond ecosystem.
- **Improved Water Quality:** AWI can enhance the overall water quality by removing other contaminants alongside algae control, making the water safer for irrigation.
- **Long-Term Solution:** While traditional algaecides provide temporary relief, AWI can offer a more sustainable solution by preventing future algal blooms.
