Automatized control systems for paper industry microbiology are coming.

IM read good news from international, net-based paper industry newsletter: oxidative agents can be measure automatically today!

Next step is obviously automatic measurement of microbial activity. A couple of analytical methods are available for this purpose. Forecast by IM is that some of them are in practical use already before the end of this decade.

This kind of automatized control needs rapid methods (like PMEU incubations and combined analytical methods to achieve fast results) for frequent evaluation of biocide alternatives, solving of trouble shooting situations and detection of harmful microbes (Bacillus cereus, Deinococcus geothermalis, Klebsiella and Burkholderia species, Sphaerotilus natans, Legionella pneumophila, amylolytic and cellulolytic microbes etc.).

Now it is the right time to start rapid control methods of paper and board machines. Colony count analyses take too much time to be a real HACCP alternative, and they are very laborous.

"NAPERVILLE, Ill., USA --June 23, 2008-- After successful trials that created improved product quality, operating cost savings and environmental and safety performance benefits for papermakers, Nalco Company (NYSE:NLC) has launched OxiPRO(tm) Deposit Control technology to the global pulp and paper industry. This novel, patent-pending control technology combines measurement, data analysis and precise dosing with proprietary chemistry to prevent unnecessary downtime and product defects. Real-time measurement of changing surface deposition, microbial activity and process conditions triggers proprietary data analysis software and on-site application experts to ensure that feed points, dosing strategies and the proper proprietary chemistries continuously optimize papermaking performance. "This new technology offers invaluable benefits to our customers - targeted to their unique application requirements - by controlling costly variability in microbial growth and surface deposits. Real-time control allows Nalco to help customers reduce operating costs and use chemistry only as needed, which reduces safety hazards and the potential for upsets to the health of the wastewater treatment plant," said Michael Meier, Nalco's Global Program Manager for Deposit Control Expertise Center.
