In this paper process conditions of debromination are investigated and equilibrium concentration of Br2 is analyzed at normal temperatures and pressures for brine waste of desalination plants. Effects of equilibrium concentration of Br2 on different temperature and pressure have been studied by process simulation. The results show air feed rate has an impact on the removal rate of Br2, the greater flow rate of air; the shorter time to achieve the balance of debromination is needed. On the other hand, the smaller flow rate of air needs the more time. It's no effect of flow rate of air on the equilibrium concentration of Br2 in brine. The higher operation temperature, the lower equilibrium concentration of Br2 can be achieved, so high temperature is good for debromination of brine waste. The lower the operating pressure is in favor of removal of Br2, however, the operating pressure has less affected on equilibrium concentration of Br2 than the operating temperature.
