New technology | Beer is mostly water, and minor ionic components have a major influence on brewing and beer quality. CapDi, a new membrane capacitance deionization technology developed by Voltea, can now offer brewers an alternative to traditional deionization treatments.
Intelligent wastewater cleaning | The development of bioelectrochemical systems for the recovery of process water permits integrated media and energy generation while simultaneously treating wastewater. This topic is addressed in a project entitled “Intelligent, hybrid, autarchic, bioelectrical systems for the generation of energy and media in the brewing industry” (I_habS).
Anaerobic wastewater treatment | A process devised by FlexBio Technologie GmbH in Einbeck, Germany, allows breweries to handle their wastewater sustainably and to exploit the energy it contains. The new generation of anaerobic wastewater treatment plants is compact and modular and provides small and medium-sized breweries especially with a solution that is economically viable.
Water worldwide | Euwa water treatment systems guarantee top water quality and economy worldwide. Its portfolio of services ranges from consulting to turnkey plants. Euwa attaches great importance to the development and use of its own technologies, the majority of which are protected by patent. BRAUWELT International spoke to Michael Eumann, managing director, and Wolfgang Winkler, technical director, about the developments in and future of water treatment.
Inactivation of bacterial contamination | Conventional disinfection methods are usually associated with high expenditure, risks and costs. This study describes use of diamond electrodes as a promising disinfection technology for inactivation of bacterial contamination in various water matrices.
Raising energy efficiency | In every brewery plant, there are places where valuable flash steam is blown off. This can principally be recovered in a simple and effective manner. Energy efficiency of a plant is thus significantly improved. This article describes various possibilities for utilising flash steam.
Sustainable solution | Good water treatment is a guarantee for good beer. Using green, resource-efficient technologies without addition of chemicals and without waste, it is possible to produce beer while simultaneously having a positive effect on the environment. Freeze crystallisation offers this exact combination for environmentally conscious beer producers.
SME compatible | The Bavarian Karmeliten Brewery in Straubing is the first German brewery to decide on a turnkey installation of a fully biological treatment plant. The carrier-based system combining anaerobic and aerobic wastewater treatment of the Dutch company Aqana completes the energy/environmental sustainability concept of a CO2 neutral brewery that has won several awards. It has been grant-aided by the German Federal Government.
USA | The Supreme Court will hear arguments in November in a major environment case concerning the Clean Water Act. Sixty craft breweries have clubbed together over the summer and told the justices in a brief that weakening the federal regulation would damage their businesses.
Flow cytometry | The risk of primary and secondary infection in beverages can be reduced if a beverage production facility is clean at all times and in all areas. Ensuring this is one of the central and cost-intensive tasks of beverage production. But how can you be sure that all pipes and equipment are always clean? How can this be monitored almost in real time?
