A system for treating high concentration textile wastewater and sludge by supercritical water oxidation and its economic analysis

The advantages in treating high concentration textile wastewater and sludge by supercritical water oxidation are briefly introduced. An originally designed supercritical water oxidation process with the innovational design of the reactor is presented. The determination of supercritical water oxidation conditions for textile pollutants treatment and selection for reactor material are highlighted. The investment and the operational cost of this system are also calculated, respectively. The results show that the supercritical water oxidation technology for treating high concentration textile wastewater and sludge is economically feasible.
