Water treatment and reuse in breweries

Physicochemical Characterization of Asmara Brewery Effluents

“…The brewing industry is water intensive and consequently produces huge volumes of wastewater despite of the beer is fifth most consuming alcoholic beverage in the world and brewing is a multibillion-dollar industry that creates jobs, generates taxes, supports agriculture and attracts tourism [3,4]. Beer brewing also characterized by the use of highquality fresh water due to public perception about the deterioration in quality of beer [3,5]. It was mentioned in several reports that for every 1 L of beer production, approximately 6 to 10 L of water is used [3,6,7].…”

Water in any brewery used typically for brewing, cleaning and cooling processes [7].…”

“…Water in any brewery used typically for brewing, cleaning and cooling processes [7]. Usually, wastewater is pre-treated within the brewery before being discharged into the waterway or municipal sewer system [3]. However, most of them dispose their effluents without adequate characterization, quantification and pre-treatment due to economic and technological constraints, which may have adverse effects on the municipal treatment plant by reducing the efficiency of waste treatment plant and overloading the system [6].…”

“…The quantity and characteristics of brewery wastewater can differ significantly from time to time and location to location as it depends on several different processes that occur within a brewery such as malting, mashing, wort processing, fermentation, filtration, bottle cleaning and packaging. [3,7]. Commonly, the effluents of the brewery are characterized by high organic load and high acidic content [3,6,7].…”

Brewing with fractionated barley

“…Several sustainability analyses have been performed on the process (Cimini & Moresi;Cordella, Tugnoli, Spadoni, Santarelli, & Zangrando, 2008;Hospido, Moreira, & Feijoo, 2005) and studies have been aimed at the re-use or prevention of by-product streams to minimize water and raw material losses and energy use (Aliyu & Bala, 2013;Köroğlu, Özkaya, Denktaş, & Çakmakci, 2014;Pérez-Bibbins, Torrado-Agrasar, Salgado, Oliveira, & Domínguez, 2015;Simate & Hill, 2015;. Even though it does not take into account every aspect of sustainability, exergy analysis is based on the second law of thermodynamics and, therefore, is considered as an objective method to compare material and energy losses occurring in a system both quantitatively and qualitatively (Dincer & Ratlamwala, 2013).…”
