Corrigendum to “Air-conditioning condensate recovery and applications—Current developments and challenges ahead” (Sustainable Cities and Society (2018) 37 (263–274), (S2210670717311435), (10.1016/j.scs.2017.11.032))

The authors regret that a paragraph (page 272, Section 4.1, Paragraph: 2, Lines: 1-20) in the originally published version of the article has verbatim content from the San Antonio Condensate Collection and Use Manual for Commercial Buildings (authored by Diana D. Glawe, San Antonio Water System, 2013) without citation of the source. Though this source was cited in five other places within this article, the authors admit missing this citation as an unintentional oversight. The revised content with author attribution is given below: Since the condensate is slightly acidic, it can react with metals (particularly iron and steel), creating tiny amounts of metal ions. While these traces are usually harmless, they can build up over time and become toxic, especially if condensate flows through metal pipes for irrigation. For applications sensitive to metal contamination, it is advisable to limit the condensate's contact with bare metal parts or ensure the condensate is properly treated and tested before use. Other inorganic substances such as salt and nutrients should also be checked, mainly when mixing condensate with reclaimed water. During AHU coil cleaning, the wastewater must be directed to the right disposal system to prevent metals (such as copper), dirt, microbes, and cleaning chemicals from entering the reclaimed water (Glawe, 2013). This correction does not affect the results, interpretations, or conclusions. The authors would like to apologize for any inconvenience caused.
