Contrary to conventional COD control methods, which emphasize the treatment of effluent in the wastewater treatment plant, the Cleanase™ COD Reduction technology focuses on preventing the generation of dissolved COD during the pulping stage. The patent-pending technology combines enzymes and nanomaterials to reduce the degradation of raw materials and induce crosslinking of certain colloidal materials on the fiber surfaces. Therefore, the novel technology attempts to solve the problem from the root causes. In addition to reducing COD discharge, it provides a high utilization efficiency of resources.
