A paper roll mill in Paperie du Rhin in France installed an MBR process based on hollow-fiber membranes (Table 19.2).The mill uses recycled (not de-inked) paper as the raw material for the production of 40,000 tons of paper rolls annually. The bioreactor (1500 m 3) is operated at an MLSS content of 12–16 g/L.The wastewater from the mill is first prescreened with drum screens; then it is .

Rolling equipment is roughly divided into three kinds; namely, hot rolling mills, cold rolling mills, and foil mills. Usually, rolling is performed by applying a load to the materials by forcing them vertically through a pair of work rolls. The work rolls are deformed by the high load during the rolling process.
