Abstract

A measurement apparatus for dewatered sludge comprises a conveyor with a reception section and a measurement section. The conveyor receives continuously or repeatedly dewatered sludge from a dehydrator at the reception section, and conveys the dewatered sludge toward a measurement section, which comprises at least one sensor. The measurement section and the conveyor together compress the dewatered sludge at the measurement section. The at least one sensor measures the dewatered sludge at the measurement section. The conveyor causes a push force to the dewatered sludge at the measurement section based on feed of the dewatered sludge from the reception section for discharging the dewatered sludge from the measurement section back to the sludge process.

Dependent claims

A measurement apparatus for dewatered sludge of wastewater treatment, wherein the measurement apparatus comprises a conveyor with a reception section and a measurement section;

the conveyor is configured to receive continuously or repeatedly dewatered sludge from a dehydrator at the reception section limited by walls, and convey the dewatered sludge toward a measurement section which comprises at least one sensor;
the measurement section and the conveyor together are configured to remove air and/or gas from the dehydrated sludge by compression of the dewatered sludge at the measurement section;
the at least one sensor is configured to measure a property of the dewatered sludge at the measurement section, the property being at least water content;
and
the conveyor that is configured to receive the dewatered sludge is configured to cause a push force to the dewatered sludge at the measurement section based on feed of the dewatered sludge from the reception section for discharge of the dewatered sludge from the measurement section back to the sludge process.
