Positive and ncgative effects of dilution of raw effluents from swine breeding are discussed, as to the treatability of those waste waters. Its effects on oxygen consumption and on the variation of inhibitory actions possibly observed, are studied and quantified. Using BRADENDER and VANDE-FUTTE techniques based on peptone degriidation, and determining PIiELPS'S equation parameters for different Consumption curves observed, the advantages of diliition VCWLIS treatment of raw effluents is studied. Receiyed June 25, 1984 * The consumption of 0, in the peptone solution (28 g N 1-l) is expressed by the equation: Lf = 259.4 X 10-o.233f
