Benefits
detailed information
This source-separated wastewater consists of two streams:
– highly concentrated black water stream from vacuum toilets
– warm grey water stream
The resulting treatment system allows for a more sustainable approach to wastewater management. The DeSaH concept is suitable for newly built or renovated housing districts, high-rise buildings, remote areas and areas where the sewer capacity is full. The possibility of high-quality effluent makes the system suitable for cases where reclaimed water can be sold or reused.
