Valmet releases the sixth generation of its Residual Measurement

Valmet released the sixth generation of the Valmet Residual Measurement (Valmet Polarox6). The new features will further optimize the bleaching process by optimizing bleaching chemical addition, protecting process equipment and improving measurement and control accuracy.

The updated Residual Measurement is reportedly equipped with the Valmet Bridge user interface, a touch screen control platform that is today a standard with Valmet sensors.

Valmet Residual Measurement provides information about bleachability when installed before the bleaching tower. It is based on pre-chemical consumption (feed-forward), allowing for a fast response to adjust chemical addition controls.

When installed after the bleaching tower, it measures the residual bleaching chemical, providing feedback for chemical dosage control and process equipment protection.

According to Valmet, the sensor improves measurement and control accuracy by eliminating under- or overdosing of bleaching chemicals. It ensures the exact chemical dosage for lignin removal and brightness control.
