3. International VDI Conference - Sewage Sludge Treatment

  • Lernen Sie Best-Practice-Beispiele namhafter Industrie-Unternehmen kennen, wie z. B. Huber, Suez, Küttner Martin, oder Remondis Aqua kennen.
  • Hören Sie Vorträge zur Erfahrung mit verschiedenen Klärschlamm-Behandlungsverfahren
  • Erfahren Sie mehr zum aktuellen Stand des kontrovers diskutierten Themas „Rückgewinnung von Phosphor aus Klärschlamm“.
  • Profitieren Sie vom Renommee des Fachleiters Prof. Dr. Peter Quicker.
Sewage Sludge Treatment - Konferenz

Die Konferenz „Sewage Sludge Treatment“ gibt Ihnen einen Überblick über heute übliche Methoden sowie künftige Strategien und Märkte. Lernen Sie innovative Verfahren der Klärschlammbehandlung sowie zur Rückgewinnung von Phosphor kennen. Auch die Rolle von Klärschlammverwertung in der Kreislaufwirtschaft spricht die Konferenz an.

Klärschlamm – Weiterverwertung statt teure Entsorgung

Die Klärschlammverwertung gewinnt vor dem Hintergrund steigender Entsorgungs- und Transportkosten sowie dem Verlangen nach Ressourcenschonung immer weiter an Bedeutung. Neben der thermischen und landwirtschaftlichen Klärschlammverwertung rücken innovative Methoden zur Rückgewinnung von Phosphor und anderen Rohstoffen zunehmend in den Mittelpunkt des Interesses. Angetrieben wird dies von politischen Entwicklungen. Dazu zählen u.a. ein langfristig absehbares Verbot der Klärschlammaufbringung auf EU-Feldern und die Einstufung von Phosphor als knapper Rohstoff durch die Europäische Kommission.

Im Fokus der internationalen Konferenz „Sewage Sludge Treatment“ stehen daher folgende Themen:

  • Thermische Behandlung von Klärschlamm
  • Phosphor-Rückgewinnung durch Klärschlammbehandlung
  • Politische Entwicklungen und die aktuelle EU-Gesetzgebung
  • Methoden zur (energetischen) Verwertung von Klärschlamm
  • Entwicklung der internationalen Märkte


The following topics will be further explored :
