BACTERIAL CONTROL MEASURES WORLD PULPPAPER60 Long-term control of bacterial spores on a board machine requires special competence to select the best control strategy for each individual machine in the world. We have seen numerous machines where this one-size-fits- all strategy has failed and when subsequently called in to help we have been able to correct the situation by applying a different philosophy and understanding to control spore formation. Kemiras toolbox to combat spores in food-packaging board is unique and the most comprehensive on the market. It includes patented products and treatment concepts such as FennoClean D patented Global annual production of hygienic board is approximately 14 million tons of which liquid packaging board LPB makes up about 5.5 million tons. Depending on end-uses of the board grades these machines have different hygiene specs and targets. Machines with the strictest targets follow the Dairyman standard with aerobic bacteria content of max. 250 CFUg of dry board. This is also the maximum accepted level according to FDA legislation for milk packages in the US market. The most common target setting in food- packaging grades is aerobic bacteria content of max. 1000 CFUg of dry board. FennoClean qSpore FennOx and CorrStrix are trademarks or registered trademarks of Kemira Oyj or its subsidiaries. diagnostics such as qSpore and patented on-line monitoring tools such as Kemira FennOx and CorrStrix. When applied correctly these can help you take the mystery frustration and costs of contamination out of your food packaging board machine. a Slime on frames b - c Clean headbox however if unaware of potential corrosion risks the intense biocide usage can create costly corrosion issues d Corrosion damages.
