Biodegradability of swine effluents II. Kinetics of pollutants removal

Some aspects of the kinetics of bioremoval of pollutants during biodegradation of swine‐breeding waste waters are studied and a biphasic model is proposed. The concentration of nitrogen and phosphorus compounds during the process is followed. Following a previous contribution on the same subject, the aspects of dilution of those effluents are discussed, and it is proposed to treat raw effluents, in spite of the reduction of possible biostatic actions. Dilution will be acceptable only if strong inhibitory effects are observed.
