(Main)Wastewater treatment plants - Part 12: Control and automation
Wastewater treatment plants - Part 12: Control and automation
This document specifies general requirements for instrumentation and specific requirements for process control and automation systems on wastewater treatment plants for more than 50 PT.
NOTE 1 Because of the rapid rate of development of sensor and control equipment, this document is intended as an overview and uses examples and general requirements, not detailed equipment specifications. Detailed information additional to that contained in this document can be obtained by referring to the Bibliography.
NOTE 2 Although EC directives become matters of law in member states of the EU and some other situations, this standard is intended for wider use and hence those directives with clear technical guidance of a type that would generally be appropriate in a standard are referenced in the text and listed in the Bibliography. The alternative of listing requirements copied from directives would potentially create unacceptable conflict when directives are revised.
Kläranlagen - Teil 12: Steuerung und Automatisierung
Dieses Dokument legt allgemeine Anforderungen an die Instrumentierung und spezifische Anforderungen an die Prozesssteuerungs- und Automatisierungssysteme von Kläranlagen für mehr als 50 EW fest.
ANMERKUNG Aufgrund der raschen Entwicklung von Sensoren und Steuerausrüstung ist dieses Dokument nur als Überblick gedacht und enthält Beispiele und allgemeine Anforderungen, jedoch keine detaillierten Spezifikationen für die technische Ausrüstung. Die in den Literaturhinweisen aufgeführten Unterlagen enthalten Einzelheiten und Hinweise, die im Rahmen dieses Dokuments verwendet werden können.
Stations d'épuration - Partie 12 : Régulation et automatisation
Le présent document spécifie des exigences générales concernant l’instrumentation et des exigences spécifiques concernant les systèmes de régulation et d’automatisation des procédés mis en œuvre dans les stations d’épuration de plus de 50 EH.
NOTE 1 En raison de l’évolution rapide des équipements de détection et de régulation, le présent document est destiné à donner une vue d’ensemble et présente donc des exemples et des exigences générales, et non des spécifications détaillées des équipements. Des informations complémentaires de celles contenues dans le présent document sont disponibles dans la Bibliographie.
NOTE 2 Bien que les directives CE aient force de loi dans les États membres de l’UE et dans certaines autres situations, la présente norme est destinée à une utilisation plus large et, par conséquent, les directives comportant des recommandations techniques claires qui seraient globalement appropriées dans une norme sont référencées dans le texte et listées dans la Bibliographie. L’alternative consistant à répertorier les exigences reprises des directives pourrait potentiellement engendrer des conflits inacceptables lors de la révision des directives.
