Natural Sciences >> ChemistryEvaporation of Volatile Organics from Basins in Seriesby John Correa
Submitted : Spring 2013 A water treatment plant uses large mixed basins in series in order to remove volatile pollutants from inlet water. The flow rate of water entering the basin system is Q = 100 m3/hr containing the benzene at a concentration of C0 g/m3. The concentration of benzene in the water immediately drops to C1 in the first basin. Benzene evaporates in the first basin at a rate of r1and the water is sent to a second basin where the benzene concentration drops to C2 and benzene evaporates at a rate r2. For the two basins in series the concentration of benzene as a function of time for the period from 0 to 1 hour was determined, as well as the maximum concentration reached in the second basin and the time at which this occurs. A graph of the concentration as a function of time was created and it was observed from this that the concentration never exceeded the 1g/m3 level. Related Links:
