Discusión del artículo: Situación actual y perspectivas futuras de la reutilización de aguas residuales como una fuente de recursos hidráulicos

[ES] El artículo indicado es una revisión excelente del tema de la reutilización, pero creemos que determinados conceptos deberían aclararse ligeramente y actualizarse, puesto que en la literatura especializada figuran de otra forma.Salgot, M.; Folch, M.

Residence time distribution and disinfection of secondary effluents by infiltration percolation

ABSTRACT Infiltration percolation is used as a tertiary treatment in order to meet the WHO's microbiological standards applying to unrestricted agricultural wastewater reuse. Faecal coliform removal, ∆fc, was investigated in laboratory columns and on a 565 m 2 pilot plant. ∆fc observed in laboratory columns was shown to be closely related to water detention time distribution, DTD. The relationship between ∆fc and DTD, which has been determined from column tests, allowed a good prediction of the disinfection performances of the pilot plant for hydraulic loads of 0.54 and 0.66 m/d. For 0.82 m/d, the maximum load that could be tested on the plant, the mean faecal coliform removal was more than 1 log. unit higher than predicted. These unexpected good performances, though calling for more comprehensive explanation, speak for the widespreading of a reliable and cost-effective extensive technique

Criteria for wastewater treatment and reuse under water scarcity

Water scarcity and water availability put significant constraints on social and economic development, as well as deteriorate the quality of life. Today, the problem of water scarcity is the adverse result of ineffective water resources management and policies, as well as the unavailability of water in arid and semiarid countries. The causes for water scarcity can be institutional, socioeconomic, and climatic physical. The scope of this chapter is to provide a general overview of the status of wastewater treatment and reuse trends and practices under potential drought and water scarcity conditions. Although the background information on wastewater reuse and the recommendation for further research identified in this study are applicable throughout the world, the primary focus is on the implementation of reuse in regions under water scarcity. At the present time, several studies have been conducted on wastewater quality and for different purposes; however, there are no regulations of water reuse at the international level. With the development of tourism and global food markets, there is a need for sharing a common rationale for developing water reuse criteria. The overall objective of recycled water use is to lead to greater allocative and distributive efficiency of water resources and include this nonconventional measure in the technical solutions to combat drought and water scarcity to be finally adopted in the areas concerned. © 2016 by Taylor & Francis Group, LLC
