The authors computed, for the effluents discharged by some food industries (meat processing, dairy and brewery), the pollution coefficients expressed in units of BOD 5, COD, suspended solids, organic nitrogen and total phosphorous. The theoretical evaluations of COD equivalents exerted by each components of the organic load (Kjeldahl N, etc.) agreed with experimental data. For BOD 5 only, the pollution coefficients were in good agreement with literature data. The tests carried out with Warburg apparatus showed that the organic loads of the wastewaters are likely to undergo sequential multicomponent biooxidation. Moreover, a good agreement was found between biological (Warburg) oxygen consumptions and total initial COD reductions. In connection with brewery wastes, experiments were make with the T(b)OD test, with very interesting results regarding the oxidizable fraction of COD and the minimum amount of oxygen for metabolic requirements.
