MadTree Brewing Craft brewer to incorporate Veolia’s Sirion™ Mega technology to produce high purity water

ast growing and critically acclaimed Cincinnati craft brewer MadTree Brewing has chosen Veolia Water Technologies’ Sirion Mega technology solution to ensure water quality control as the brewer undergoes a planned expansion.

MAINTAIN PRODUCT QUALITY

The 100 GPM (gallons per minute) RO unit produces high purity water, removing up to 97% of dissolved inorganic and more than 99% of large dissolved organic material, colloids and particles—providing consistent water quality for MadTree’s beer production process. Any excess output from the RO will be directed to the boiler as water make-up thereby further delivering increased water & energy eﬃciency in operations. Currently producing approximately 25,000 barrels of beer a year, the brewery expansion will increase production to 35,000 barrels annually. Furthermore there is enough room to support future growth by adding potential capacity to boost output to 180,000 barrels. According to co-founder Jeﬀ Hunt, maintaining product quality was the brewer’s over-riding objective when it contemplated expanding production to meet increased customer demand. "Since water makes up 95% of beer, water quality plays an important part influencing our beer’s flavor profile. As we planned for our new, expanded production facility it was critical to us to be able to control the incoming water of our brewing process to insure we maintained

consistent quality and taste of the beers. As such, we didn't want a standard RO unit.” Hunt continued: “What we found most appealing about Veolia's RO technology was its ability to provide feedback, which will allow us to fine-tune the incoming water as needed to be able to produce the high quality of beers our customers expect. Moving ahead we are fortunate to be able to call upon Veolia's industry experience and technological expertise to help make sure we maintain the high quality standards that have fueled our growth.” As part of the largest water company in the world, Veolia Water Technologies enjoys a commanding presence in the beer brewing industry with more than 150 – and growing – brewery customers globally. Veolia’s more than 350 proprietary technologies support its solutions and service value across the entire spectrum of the brewing process – from product & process water, to water recycling and wastewater solutions. “We’ve seen the explosive growth in the craft brewing sector of the market, particularly in the U.S.,” said Ted Lawson, Marketing Director for Veolia Water Technologies, “and we recognize the growing needs these brewers have for improving both process water and wastewater treatment. We are committed to leveraging our technical knowledge and experience to add value by helping emerging brewers grow and succeed.” ●

Paulaner brewery

Environmentally friendly wastewater treatment

he Paulaner brewery is one of the bestknown German breweries, with a long tradition of the finest Munich art of brewing. The annual production exceeds 2 million hectoliters. The popularity of Paulaner beer has always extended beyond the city limits of Munich, both nationally and internationally. Paulaner beer is enjoyed in more than 70 countries worldwide.

The challenge Due to the increasing popularity of Paulaner beer the existing production site Nockherberg in the center of Munich reached its limits. In order to secure ample capacities for future growth, Paulaner decided to move the production to Munich-Langwied. The new site has suﬃcient space as well as excellent connections to the highway. The new brewery had to be built with an emphasis on modern and environmentally friendly brewery technology as well as an energy and emission-optimized infrastructure.

The solution The beer production process generates organically loaded wastewater streams which are easily biodegradable. With conventional biological treatment, biological degradation is

achieved by using aerobic organisms. These, however, need to be fed with oxygen, resulting in high operating costs and CO2 emissions. Paulaner selected an environmentally friendly anaerobic treatment. The degradation process does not need oxygen, so the energy consumption is considerably reduced. Another advantage is the production of energy-rich biogas, which can be used on site in the boiler house. To ensure a high level of operational reliability for their future wastewater treatment, Paulaner chose the proven Biobed® system supplied by Aquantis, a German subsidiary of the leading Veolia Water Technologies group. ●
