Measure paper strength potential with greater precision


N


ew capabilities have been added to the FS5 fibre image analyser offered


by Valmet, enhancing a paper maker’s ability to measure paper strength potential. These features are said to take the laboratory testing of pulp and paper fibre samples to a new level. Launched in 2013, more than


60 Valmet FS5 analysers are now in use, continuing Valmet’s 30- year fibre analytics history with more than 1,000 fibre property measurements delivered. Fully meeting the ISO fibre


length measurement standard requirements, the analyser is said to be simple to use with no lengthy training needed. Easily measuring the fibre properties of 100 samples in an eight-hour


shift, the automatic consistency adjustment eliminates operator error by allowing samples to be inserted without any special preparation. Analysers are individually


customisable, equipped with only the required measurements and easily programmable for analysis and reporting. Maintenance requirements are minimal and no on-site calibration is required as each unit is calibrated with an accredited calibration tool at Valmet’s production centre at Kajaani in Finland. The strength potential of the pulp can now be predicted easily from the process samples. Better understanding of the characteristics of the fibres helps paper makers to manage the process and get targeted end


product quality by optimising the blend and using less energy, for example, in grinding. “The new gravimetric


coarseness feature in FS5 has been accepted very well by our customers,” says Tuomo Kälkäjä, product manager for Valmet FS5. “The true coarseness value is an important value which predicts the paper structure and now it is possible to get this result easier and faster than ever before without tedious and time-consuming sample preparation. Based on user feedback


Valmet has implemented improvements to the operator interface, including customisable


measurement templates and reports. Valmet FS5 is now easier than before to use in regular mill testing, and it also meets the requirements of research laboratory use. The increased capabilities offered by these new measurements and improved interface are also available as upgrades for existing users.


Dry cake measurement improves dewatered sludge quality in wastewater treatment


A device for measuring dry cake solids for dewatering control in waste water treatment complements Valmet’s wastewater control range. The Valmet DS’s low-power


microwave technology enables stable and accurate measurements, which can be utilised by the feedback control to optimise polymer dosage and centrifuge. This decreases energy consumption through better torque control. “The Valmet Dry Solids


Measurement helps our customers take their performance forward,” says

Internet functionalities allow full access to the measurement data, alarms and diagnostics that are all remotely accessible. The TZ Osbourne wastewater


Jarmo Havana, product manager at Valmet. “Remarkable polymer and


energy savings can be achieved through continuous and reliable solids measurement. By maximising drying efficiency to a target dry cake solids content, additional savings can


be achieved through reduced transportation costs and fuel consumption during incineration.” Valmet DS is typically located in the downfall section of the dry cake with a screw conveying the sample to the microwave sensor chamber before it is returned to the process. The Industrial


treatment plant in Greensboro, North Carolina, USA, has achieved a reduction in polymer of up to 25 per cent, says Valmet. The Viinikanlahti wastewater treatment plant in Finland is also providing good results. “Valmet DS is a reliable online measurement. We can now really see how well the centrifuge is operating,” says Sami Ilomäki, operations engineer at the Tampere Water plant.
