PP-Washing Process Ltd has worked for more than ten years with cleaning problems on paper machines and their wet end. During that time, PP-Washing Process has developed online cleaning solutions in co-operation with many modern paper mills. Today, it is possible to find maintenance-free, online cleaning units in storage tanks for fibre and water, dosage tanks and in wire section areas.rnCompetition in the efficiency and productivity of paper machines becomes increasingly harder, and this competition occurs also within companies, between various production units. Therefore, more and more devices for online observation and control have been installed on paper machines. However, it is quite common that the relationship between the length of production periods and frequency of shutdowns is forgotten. It is accepted that the machine is shut down every three or four weeks. These stops are either maintenance shutdowns or washing shutdowns.
