In the food and beverage industries, spent process water streams containing very different levels of contamination are combined and routed to the mixing and equalizing tank where problems in biological wastewater treatment occur. It could be shown that the treatment of the partial streams for differ

An integrated membrane filtration process was developed to produce water of drinking quality out of polluted process water from small and medium-sized enterprises in the food and beverage industries. It comprised a membranesupported bioreactor and a combined nanofiltration/UV disinfection stage. The

In this study, it could be shown that, drinking water consumption in the food industry could be drastically reduced by water reuse. Boiler make-up water or warm cleaning water could be economically produced from lowcontaminated process water (electrical conductivity below 3000 µS/cm and COD below 70

Within the framework of our new technological concept for the desalination of surface water to industrial water, the production of a mixed acid and a mixed base by electrodialysis with bipolar membranes (EDBM) from effluents was one main objective of the study. After optimized pretreatment, reverse
