Reuso de água proveniente de aparelhos de ar condicionado para fins de irrigação em microescala.

Abstract

Water scarcity in arid and semi-arid regions is becoming more frequent and more remains for longer periods of time. In this sense it is necessary to search for alternatives of reuse of water originating from different sources, provided that their quality aspects can be monitored to guarantee production in the rural environment of family origin. The objective of this work is to present an alternative use of water generated by air conditioning devices commonly used in school, commercial, industrial and residential environments in tropical regions as a way of replacing the use of well water for microscale irrigation. The quality of the water collected through the air conditioners is better than the water from the well used for irrigation of the experimental area of the CDSA/UFCG. The estimated amount of water is enough to irrigate an area of 500 m² with a daily 5mm. The idea can and should be applied in any environment, because it favors the reduction of water consumption, strengthens the concept of water sustainability, reduces the environmental impact on the soil that will have a longer time of use without risk of salinization, maintaining its structure and function preserved, in addition to bringing the involvement of the academic community on the need to save water resources that are increasingly scarce.
