Aproveitamento das águas descartadas por aparelhos de ar condicionados para fins de reúso não potável

Abstract

The objective of this study was to determine the physico-chemical composition of the wastewater by residential air conditioners, since the use of this type of water appears as a reuse option for non-potable purposes. Resolution No. 54 of November 28, 2005, of the National Water Resources Council, establishes modalities, guidelines and general criteria for the policy of direct non-potable water reuse. For the study, eight samples of water discarded by residential air conditioners were collected in March, April and May 2019, in which physical-chemical analyzes of the parameters were performed, which are indicators of which type of water reuse be used. The physicochemical analyzes followed the procedures described (APHA, 2012) and were carried out in the Laboratory of Environmental Chemistry of the Nucleus of Industrial Technology of Ceará (NUTEC).
