    Application of ornamental plants in constructed wetlands for wastewater treatment: A scientometric analysis
    (2023) García Ávila, Fausto Fernando; Guanuchi Quito, Alexandra Elizabeth; Avilés Añazco, Alex Manuel
    The application of ornamental plants in constructed wetlands (CW) is increasingly of interest to researchers, professionals actively involved in wetland management and/or wastewater treatment (WWT), so it is necessary to know the trends in this field of research. The objective of this study was to develop a scientometric study on the use of ornamental plants in CWs for the WWT during the period 2002–2022. For this, a search of the information was carried out in the Scopus database, including all the articles and reviews related to this field. The analysis of the recovered documents allowed to know key aspects of the evolution of production in recent years, the maturity of research in this field, identify the most used ornamental plants and therefore identify gaps. Likewise, it was possible to identify the countries, the most relevant authors, the main journals and the most cited articles through which knowledge in this area is disseminated. The results showed that Mexico, Brazil, USA, China and India have the highest number of publications related to the use of ornamental plants in the CWs. It was found that the most used ornamental plants are Canna, Iris, Heliconia and Zantedeschia. This analysis can help researchers to identify new research approaches in this field. It is concluded that this field of knowledge has aroused great interest since 2002; however, more research can still be carried out on the application of CWs with ornamental plants in cold climates, the influence of the substrate on the growth of these plants.

    Vertical tubular flocculator: alternative technology for the improvement of drinking water treatment processes in rural areas
    (2023) Avilés Añazco, Alex Manuel; García Ávila, Fausto Fernando; Tenesaca Pintado, Darwin Adrian; Guanuchi Quito, Alexandra Elizabeth; Tonon Ordoñez, Maria Dolores; Novoa Zamora, Carlos Francisco
    The guarantee of access to safe drinking water for rural communities is a great challenge due to the increase in contamination and deterioration of water sources. Rural areas face technological, financial, and operational limitations, having poor water quality, generally. The purpose of this study was to evaluate the efficiency of a vertical tubular flocculator (VTF) to be used as part of the purification process in rural areas where small flows are used. An experimental treatment system (ETS) implemented in the field was used. The VTF was implemented using PVC pipes and fittings. Tests were carried out with the same raw water used from a conventional treatment plant with aluminum sulfate as a coagulant. The optimal coagulant dose applied in the ETS was determined by the jar test. In the VTF, the length, turbidity, and flow of the raw water were varied. The hydraulic behaviour of the VTF was evaluated with the analysis of the time distribution curve of concentration of a tracer applying the Wolf-Resnick model. A low residence time VTF was obtained, representing a new efficient flocculation model for the reduction of turbidity and colour. The results showed that the turbidity of the raw water, the residence time, and the degree of agitation are important parameters in the operation and efficiency of a VTF. There was a predominance of plug flow in the reactor. The obtained results were compared with the efficiency of a conventional water treatment plant used in the study site. The results obtained indicated that this ETS that integrates a VTF with settling and filtration can be a useful tool for rural areas. It was recommended to replicate this study with wastewater, other dimensions of the VTF, to establish a specific methodology for the design of the VTF, to evaluate the dosage with dose bombs for improving the results of VTF, and to elaborate a hydraulic model for VTF
