Significantly reduced sludge volume with SOLITAX highline sc

The agricultural utilisation of dried sludge from municipal sewage treatment plants is becoming more difficult and therefore more expensive. The costs of sewage sludge disposal in Europe are estimated at 2.2 billion euros, provided the current high level of utilisation for agricultural and landscaping purposes is maintained (60%). If thermal disposal becomes mandatory, the costs will rise by 40% to more than 3 billion euros*. The volume of sludge can be significantly reduced with the help of the SOLITAX highline sc solids probe. This has been demonstrated at the sewage treatment plant in Papenburg (PE 48,000; Fig. 1).
