Sewage Treatment Plant Handewitt

Project description

The community of Handewitt, as well as their surrounding area is growing steadily, therefore the wastewater treatment plant in Handewitt has to be extended and optimized.
As part of the preliminary planning, various procedures and expansion options were developed. Among others, the existing solar drying for the sewage sludge should be adjusted in the process of expansion.
There were proposed solutions with correspondingly large sludge storage, which drain the sludge as needed with its own mechanical sludge dewatering in the container, but also the construction of a stationary machine sludge dewatering was proposed.

Furthermore, it was advisable to supply the solar drying with an additional waste heat flow, gained by a natural gas cogeneration plant which needs to be installed. That would secure the achievement of needed degree for drying even in the winter months, in order to dry up the increased sewage sludge volume safely over the year.

The supply of additional heat in the existing solar dryer, proved to be uneconomical, as the dryer consists only a single glazing and therefore the additional spent energy would have high losses especially in the winter months.
It results in the extension of the solar drying by a covered mud storage facility to store the sludge build-up in front of the solar dryer to provide safe sludge management throughout the year. The dried sewage sludge then goes on to a newly built granulate warehouse. Both facilities ensure sludge treatment required over the year very economically. Machine sludge dewatering is ensured by an additionally installed mobile device in the container, which can also be installed on other treatment plants within the association area if required, but will essentially be available for the wastewater treatment plant in Handewitt in the future.
