Abstract
Objectives: Report the exploratory study results of the performance of a conventional solar still prototype using seawater and brackish water (river and well) at three locations in northern Chile at different geographical heights. Materials and methods: A solar still with an effective distillation area of 0.54 m2 was used. Three tests were performed with seawater, 1 with river water and 1 with well water. The temperatures and environmental parameters were measured every 10 minutes for 36 continuous hours. The efficiency was evaluated in terms of seawater and the capacity to remove natural contaminants from brackish water. Results and discussion: The productivity in the three selected areas was 3 and 4 L/m2 for seawater and brackish water, respectively. The removal of boron and arsenic complies with the regulations of the country. Conclusion: The results obtained are of exploratory character for the zones, where the geographic height and the total dissolved solids are factors that determine the performance of a passive solar still, which is higher when water is used with low concentrations of solids.
期刊介绍:
Our journal''s main objective is to serve as a medium for the diffusion and divulgation of the articles and investigations in the engineering scientific and investigative fields. All the documents presented as result of an investigation will be received, as well as any review about engineering, this includes essays that might contribute to the academic and scientific discussion of any of the branches of engineering. Any contribution to the subject related to engineering development, ethics, values, or its relations with policies, culture, society and environmental fields are welcome. The publication frequency is semestral.
