Valmet, a global developer and supplier of process technologies, automation and services for pulp, paper and energy industries, has launched the sixth generation of its Valmet Residual Measurement, called Valmet Polarox6. This update aims at further optimization of the bleaching process by optimizing bleaching chemical reaction, protecting process equipment and improving measurement and control accuracy.

The sixth generation update is equipped with the Valmet Bridge user interface, a touchscreen control platform commonly used with Valmet sensors. The user interface provides intuitive access to transmitter operation and Valmet’s remote services with comprehensive diagnostics and Valmet industrial internet ready capabilities.

“This update ensures the longevity and advanced connectivity of our industry standard Valmet Residual Measurement for all pulp bleaching applications,” says Timo Laurila, Business Manager, Pulp and Energy Analyzers, Automation Systems, Valmet.

Technical information

Valmet Residual Measurement provides immediate 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 accurate feedback for chemical dosage control and process equipment protection.

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, resulting in chemical savings and better-quality fibers. Additionally, the operation is safer due to no excess residual.

2023 promises an interesting ride for print in India

Indian Printer and Publisher founded in 1979 is the oldest B2B trade publication in the multi-platform and multi-channel IPPGroup. While the print and packaging industries have been resilient in the past 33 months since the pandemic lockdown of 25 March 2020, the commercial printing and newspaper industries have yet to recover their pre-Covid trajectory.

The fragmented commercial printing industry faces substantial challenges as does the newspaper industry. While digital short-run printing and the signage industry seem to be recovering a bit faster, ultimately their growth will also be moderated by the progress of the overall economy. On the other hand book printing exports are doing well but they too face several supply-chain and logistics challenges.

The price of publication papers including newsprint has been high in the past year while availability is diminished by several mills shutting down their publication paper and newsprint machines in the past four years. Indian paper mills are also exporting many types of paper and have raised prices for Indian printers. To some extent, this has helped in the recovery of the digital printing industry with its on-demand short-run and low-wastage paradigm.

Ultimately digital print and other digital channels will help print grow in a country where we are still far behind in our paper and print consumption and where digital is a leapfrog technology that will only increase the demand for print in the foreseeable future. For instance, there is no alternative to a rise in textbook consumption but this segment will only reach normality in the next financial year beginning on 1 April 2023.

Thus while the new normal is a moving target and many commercial printers look to diversification, we believe that our target audiences may shift and change. Like them, we will also have to adapt with agility to keep up with their business and technical information needs.

Our 2023 media kit is ready, and it is the right time to take stock and reconnect with your potential markets and customers. Print is the glue for the growth of liberal education, new industry, and an emerging economy. We seek your participation in what promises to be an interesting ride.
