Abstract
The present invention is an oxidative reaction that converts organic content in the wastewater into harmless CO2 and H2O. The heat produced by the oxidative reaction evaporates the water, thereby concentrating the remaining solids in solution. The final product from the process is the crystal form of sodium carbonates and other oxidized salts carried in by the raw wastewater.
