THE CHEMICAL COMPOSITION OF A BREWERY WASTE

Abstract

Detailed chemical analyses of eight composite samples and of one snap sample of a combined effluent from the brewhouse and cellars of a brewery with a total waste‐water flow of about one half a million gallons per day are described. Seven of these composite samples were collected on the different days of a typical week. Special attention is given to the extreme variations occurring in the chemical composition of the waste and to the possible deficiency in nutrients such as nitrogen and phosphorus with regard to biological treatment of the effluent. 1965 The Institute of Brewing & Distilling
