Water Reuse - Treatment Technology Advances and Applications

摘要

Non-potable reuse applications of reclaimed water typically require conventional wastewatertreatment technologies that are already widely practiced and readily available in many countriesthroughout the world. Higher level uses, such as irrigation of public-access lands or vegetables tobe consumed without processing, require a higher level of treatment and treatment processreliability, than for uses such as irrigation of forage crops and pasture. As uses such as indirectpotable reuse and even direct potable reuse are being considered more widely in efforts toaddress increasing demands on water supplies, additional treatment will be required. Thus, whenconsidering treatment processes for a reuse system, the overriding concern continues to bewhether the quality of the reclaimed water is appropriate for the intended use. This presentationprovides an overview of the range of intended uses of reclaimed water and the appropriatetreatment technologies that are available to meet the treatment requirements for the production ofsafe, reliable reclaimed water for these uses. Additionally, a brief discussion of the need toconsider and evaluate additional and more advanced treatment technologies for facilitiesproviding either indirect or potentially direct potable reuse is provided.
