Safe water reuse through a quasi-natural water cycle

Abstract Safe water reuse usually means the provision of reclaimed with its quality meeting criteria for safeguarding human health and aquatic ecology. Regarding this, people often overstress technological magic in terms hazardous substances removal by engineered processes while ignoring utilization nature's power to provide an additional barrier safety control. Based on understanding function hydrological cycle secure fact that is through a loop, author presented his viewpoint creating quasi-natural reuse. Existing data showed remarkable effects emerging pollutants associated reduction biotoxicities from during open-storage under condition. Adsorption soil particles, sunlight-induced photolysis purification life were thought be major actions contributing effective improvement manner. can thus recommendable strategy system design accordance purposes use.
