Method and Apparatus for Treatment of a Biological Suspension

Simple SummaryContent extracted from patent full text and abstract with AI.

The invention describes a method and apparatus for treating biological suspensions, such as sewage sludge or manure, by exposing them to ozone and heating them to at least 50°C. This process significantly reduces the viscosity of the suspension, which aids its further processing and handling.

Use CasesContent extracted from patent full text and abstract with AI.

• Treatment and conditioning of sewage sludge at wastewater treatment plants
• Processing manure in agricultural operations for easier handling or disposal
• Processing fermentation residues from biogas plants to improve downstream processing
• Pretreatment in facilities that recycle or dispose of organic waste materials

BenefitsContent extracted from patent full text and abstract with AI.

• Reduces viscosity of biological suspensions, making them easier to pump and handle
• Improves efficiency of sludge dewatering and separation processes
• Potentially reduces costs and energy usage related to sludge and waste treatment
• Enhances overall effectiveness of biological waste management processes

Patent Abstract

Es wird ein Verfahren zur Behandlung einer biologischen Suspension angegeben. Dabei wird die biologische Suspension mit Ozon behandelt und auf eine Temperatur von mindestens 50 °C erwärmt. Das Verfahren kann insbesondere zur Verringerung der Viskosität einer biologischen Suspension verwendet werden, um die Aufbereitung von zum Beispiel Klärschlamm, Gülle oder Gärresten zu verbessern. Ferner wird eine Vorrichtung zur Durchführung des Verfahrens angegeben.
