The designing of plants for brewery waste water treatment is seriously hampered by the fact that published figures for the biochemical oxygen demand (B.O.D.) of brewery waste are so discordant that no generally applicable averages can be extracted from them. Even in an operating brewery it is a costly and time‐consuming affair to procure representative figures by direct measurements, owing to the intricacy of the sampling problems and the inaccuracy of the analytical methods. In an effort to meet this need it is suggested that an objective and sufficiently exact basis for planning treatment plants and for costing treatment is obtainable by estimating the volume and B.O.D. of brewery waste by calculation. It is demonstrated by reference to a practical example how such calculations may be made by keeping account of all materials going into or leaving the brewery.
