21 WATER CONSUMPTION DE Filtration Water in a DE filter is used for flushing out the DE, cleaning and sterilization Consumption depends on run volumes Typical consumption is hl/hl Membrane Filtration Water in a BMF is used for periodical back flushing with cold caustic and regeneration of the membranes Consumption depends on achieved run volumes Typical consumption is 0.2 hl/hl, lower for beers produced with adjuncts and use of extra enzymes PENTAIR The role of a beer membrane filter in an environmental friendly brewery 21

22 SOLID WASTE STREAM Typical solid waste stream of a brewery is 0.8 kg/hl DE is responsible for 50% being 0.4 kg/hl For a brewery with an annual output of 1,000,000 HL it means the following: DE Filter: 400,000 kg/yr BMF: 180 kg/yr(replacement of membranes) PENTAIR The role of a beer membrane filter in an environmental friendly brewery 22
