Depending on its size, a filtration process may consume thousands of filter cloths per year. By gathering information with radio-frequency identification (RFID) technology, this application can analyze the performance of filter cloths and filters.
 
The company says it is able to use information on cloth lifetimes, the reasons for cloth removal and cloth consumption to optimize the whole filtration process. In addition, this information helps process operators to better monitor the filter itself.
 
Valmet's application is based on special equipment and RFID tags that submit information to be used in the follow-up and analysis of the whole filtration process. RFID technology has been in use for decades, but Valmet is the first to utilize it for filter cloths.
 
Valmet has developed the application in co-operation with customers and filter manufacturers. The application is initially being used in the mining industry.
