Aquaritrol : Optimiser le traitement de l'eau grâce à un contrôle automatisé de la coagulation
Introduction
Un traitement efficace de l'eau repose sur un contrôle précis des processus de coagulation. Traditionnellement, cela impliquait des ajustements manuels basés sur l'expérience de l'opérateur et des tests de laboratoire périodiques, conduisant à une qualité d'eau inconstante et à des inefficacités opérationnelles potentielles. Aquaritrol, un système révolutionnaire de contrôle des coagulants développé par USFilter/Microfloc, utilise des contrôleurs programmables pour automatiser le processus de coagulation, garantissant une qualité d'eau optimale tout en réduisant les coûts opérationnels.
Qu'est-ce qu'Aquaritrol ?
Aquaritrol est un système sophistiqué qui intègre une technologie avancée pour automatiser le dosage des coagulants dans les stations de traitement de l'eau. Ce système utilise un automate programmable (PLC) pour analyser les données en temps réel de la qualité de l'eau, telles que la turbidité, le pH et le débit, et pour ajuster dynamiquement le débit d'alimentation du coagulant en conséquence.
