Sludge disposal
During treatment, the solid substances contained in the sludge water are separated out as a concentrate. The constituents of the concentrate exceed the threshold values of Appendix 31 of the Waste Water Directive for channelling into the public sewerage system, so they must be disposed of separately.
The rule of thumb here is that approx. 1‰ of the quantity of recycled sludge water must be disposed of as sludge.
We recommend the following methods for dealing with the concentrate:
- Storage in the sludge water storage tank and direct disposal
- Interim storage in a container
- Thickening in a centrifuge and interim storage in a container
Storage in the sludge water storage tank and direct disposal
If the sludge water storage tank has sufficient capacity to take at least the quantity of sludge generated in six months on top of the greatest anticipated sludge water volume, it is usually not worth installing your own sludge treatment system.
Interim storage in a container
If the sludge water storage tank is just large enough to take the sludge water, a container is an inexpensive solution for continually removing the sludge. The container is designed in such a way that it can be taken from the disposal company directly to the landfill site. Transferring the contents is not necessary. After emptying, the container is directly reconnected.
Thickening in a centrifuge and interim storage in a container
Depending on the specific disposal costs, it can make good economic sense if you anticipate sludge quantities of more than 50,000 m³/a to dehydrate the sludge on site. If you use a fully automatic centrifuge, you can reduce the disposal quantity by about 50%.
