Metso has developed a new technology with which municipal and industrial wastewater plants are able to improve their performance and reduce the amount of chemicals used in sludge drying process by even up to one third. The potential users of this innovation include all large wastewater treatment plants in the world. The new technology features an advanced online measurement system for processing sludge, which is an integral part of wastewater treatment.
Thanks to a measurement system based on LED and laser technologies, it is now possible to separate dry solids and water from each other more accurately and efficiently than before. In this way, the amount of water treated at a plant can be significantly increased and the amount of chemicals used in the sludge drying process can be decreased by 30%.

In addition to higher capacity and lower chemical costs, savings are gained as the transportation costs of the dry solids separated from sludge decrease. The further use of the dewatered sludge in energy production is also significantly more efficient, as dewatered sludge contains less water than before.
