LDO offers 80 % less maintenance within paper industry
For many years there has been a strong trend towards resource conserving production in order to cut water consumption in the paper industry. Nevertheless, in 2004 an average of 9.6 litres of wastewater was generated per kilogram of paper in Germany. Several paper mills, which together account for more than 75 % of the gross production volume, use biological processes to treat their wastewater. In Neuss, Germany, Procter & Gamble (TEMPO paper handkerchiefs, etc.) has Europe’s biggest factory for paper-based hygiene products. Its biological wastewater treatment plant became operational in 1994. The reliable aeration control system uses the LDO optical oxygen sensor. This H2S resistent sensor enabled the monthly maintenance time to be reduced by 80 %.
