A lot should be considered when you open your brewery like craft brewing tech, brewery equipment cost and price,find a location for brewery, license and regulation of a brewery. This article column Let's take about blending water for brewing.An example of such blending systems in use can be found in the treatment of water for the brewing industry. The taste and quality of a beer is highly dependent on the quality of the brewing water. It is no coincidence that large and small breweries alike have flourished in locations that have a natural supply of especially suitable water. These days, in order to maintain a characteristic beer taste – and meet standards of quality – breweries must use water treatment plants. The decisive parameter in such cases is the degree of hardness. Soft water is needed to allow the beer aroma to develop – a fact well known by the master brewers of the traditional Swiss Egger brewery in Worb near Bern. The company’s origins go back more than 150 years. Michael Egger, Production & GL Manager, explains: “We are fortunate in that even before we started using a water treatment plant, our well water was already very pure and of high quality. In the past, our main problem had to do with the relatively high calcium content in the raw water. This led to scale buildup, especially in parts of the plant using hot water, as well as equipment malfunctions and therefore a lot of extra maintenance work.”
The task facing the plant engineering company, Veolia Water Technologies Deutschland GmbH, was to implement a tailored water treatment plant with regulated blending in the brewery as a stand-alone solution. This plant was to operate independently of the production control system, producing brewing water of the required quality, with precision and reliability, for the subsequent production processes.
These requirements were attained by means of a blending unit, which we supplied. The Veolia treatment plant splits the raw water into two separate streams: one remains untreated and one provides the infeed for the reverse osmosis process. The raw water is then fed into the salt-free permeate from the reverse osmosis process in a constant proportion, which can also be adjusted. As the quality of the raw water is stable, this fixed proportional setting suffices to meet the quality requirements. The blending proportions are controlled by means of a Type 8611 compact controller. In addition, the fast-response Type 8011 and Type S030 flow meters measure the flow rates of each stream. This produces the right blend of brewing water, reliably and with the desired quality.
Good brewing water and optimised operating costs
The blending system ensures that no more permeate is used than is necessary. This saves money in the reverse osmosis process and means longer maintenance intervals for the plant, which also has a longer lifespan. As a result, the Egger brewery not only increased the quality of its products, but also improved its cost effectiveness. “The new system means significantly less outlay for cleaning, descaling, maintenance and repairs. In addition, the energy consumption is lower because the heat transfer performance of the plate heat exchangers has improved,” adds Michael Egger.
As the plant also operates on a batch basis – in other words, it periodically replenishes a tank that is used to supply the continuous production of beer – it was also possible to install the system without interrupting the production process. As a consequence, there is now a supply of water for brewing whose quality remains constant. This in turn ensures that each recipe delivers a consistent taste for the type of beer concerned; and all achieved without modifying the existing plant.
