Pollutant in the rivers made the oxygen dissolved in the water decrease. It is because the dissolved oxygen absorbed by microorganism forxorganic waste degradation process. It’s called deoxygenation. Deoxygenation made dissolved oxygen decrease. Ones of river pollution modelling based on dissolved oxygen is influence by deoxygenation process. Rate of dissolved oxygen that used for deoxygenation proportional with biochemical oxygen demand remain. Thus, mathematics modeling of rivers pollutant based on dissolved oxygen given: (1) where is amount of dissolved oxygen at t time (mg/L), k is constant, Qw is rate of rivers flow (m3/s), Qr is rate of water pollutant flow (m3/s), Lw adalah rate biochemical oxygen demand of rivers (mg/L), Lr is rate biochemical oxygen demand of water pollutant (mg/L). Based on the equation (1), the level of pollutant will known from amount of the dissolved oxygen in the water at t time.
