This process can take up to two days. Therefore, there are two such biodigesters where the daily incoming sludge is transferred alternately. For further dewatering, the sludge is then transferred to open sludge drying beds which are connected to percolation pits so that the last of the liquid drains out.

As this activated sludge is about 97% water, sand drying beds or machines are used to remove water. The dried sludge is now used as manure, thereby returning the organic matter and nutrients to the soil. The treated water has a very low level of organic and suspended matter and is hence discharged into seas, rivers or into the ground.
