Aufbereitung von Brauereiabwasser bis zur Wiederverwendbarkeit

The buffering and balancing basins of a brewery have been developed to an aerobic wastewater treatment plant. The procedures have been adapted on the demands of the further treatment. One- and two stage membrane-plants have been piloted, a cleaning concept has been developed and filtrates and permeates produced have been analysed.It became evident that the two stage plants and a flat membrane reverse osmosis plant were suitable in technical respect. Chemical and physical properties met the demands of German drinking water law. In microbiological respect some further treatment is necessary. Ceramic and submerged hollow fibre ultra filtration membranes were as well suitable for pre-treatment of biologically treated and clarified wastewater for reverse osmosis as micro filtration membranes in pressure tubes. By taking the waste water directly from the bioreactor used as an MBR even more advantages seem to be available. That is the reason why the decision for investment was made for that kind of technology that can be developed to an complete MBR-plant. The side stream MBR of Wehrle might be a feasible alternative to the tested systems, but another Piloting would have taken too much time. Wherever MBR-technology is practised the option to recovery of wastewater seems to be within easy reach.Wherever wastewater treatment has to be reengineered MBR-technology specially as side stream system constitutes an interesting option providing the possibility of recovering water.
