Cellulose Assisted Dewatering of Sludge (CADoS)

The object of the CADoS project is to develop and to build a prototype of the Cellulose Assisted Dewatering of Sludge (CADoS) water treatment concept at the Ulrum sewage-treatment plant. The CADoS principle will be applied to use a new sieving technology innovatively within an existing wastewater treatment process. Wastewater carried via sewers to the treatment plant contains solid matter that includes a large proportion of cellulose. The cellulose stems from the use of toilet paper. The project will separate the solid matter containing cellulose that is present in the sewage water by means of a fine sieve and will use the separated solid matter for the dewatering of sewage sludge. The CADoS principle is being applied to attempt to reduce significantly the use of chemicals at the treatment plant, to consume less energy and to lower sludge processing costs. CADoS will also increase the energy yield from biogas in the fermentation of sludge.
