Analysis of a High Andean River's Behavior at Loads of Organic Matter Through the Use of Mathematical Models with Experimentally Determined Kinetic Rates

Using models of organic matter degradation and dissolved oxygen consumption, the concentrations these compounds are analyzed in two stretches a river after discharge raw sewage. The has low drafts widths, so velocity is high aeration coefficient kr calculated with Covar method high, this indicates rapid recovery from water consumed by processes, been instrumented to measure flows at various points calibrate model. hydraulic parameters section three control points, each one sample taken analyze consumption nitrification through laboratory tests determine adjust kinetics processes (kd; knit). This have used development quality model verify its adjustment, obtaining higher RMSE results than secondary sources. It observed that an excellent capacity for self-purification due income oxygen, > 9 d-1.
