Applications of Nanozymes in Wastewater Treatment

Abstract

Hazardous waste containing wastewaters should be treated with efficient and economically feasible methods for sustainable water management. Adaptations of novel wastewater treatment methods are required to protect the environment and to provide a high level of health protection. Conventional methods need to be combined with advanced methods to remove the toxic contaminants from wastewater. Treatment of wastewater with enzymes has been shown to improve the treatment efficiency with reduced sludge volume and reduced odour. High cost and stability of the enzymes are major limitations for the implications of enzymes in wastewater treatment. Nanomaterials with an enzyme-like activity, which are called nanozymes, are emerging as potential alternatives for natural enzymes in wastewater treatment.
