Metso technology lowers chemical costs at wastewater treatment plants

The new Metso technology features an advanced online measurement system for processing sludge. With the new measurement system, which is 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. As a result, 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%.

“The new technology developed by Metso offers the world’s water treatment plants an opportunity to improve their performance and thus gain major cost savings. A large North American wastewater treatment plant has calculated that it saves even up to 30% in its annual US$2.5 million chemical costs,” said Timo Rantala, product manager at Metso’s Automation business line.

Metso believes that the new technology will initially interest large wastewater plants in Western Europe and North America with high levels of automation. “It is these plants that often have major capacity issues and are under pressure to save costs. Interest in these kinds of solutions is growing in Asia, too,” added Rantala.
