    Determinación de las características físicas de sustancias reactivas: carbón activado, piedra caliza, turba, de origen ecuatoriano para el tratamiento de agua

    The present technical work has the purpose of provide information on the physical and chemical properties of substances of Ecuadorian origin for water treatment and the presentation of plans for a permeability measurement system. In the first place, a bibliographic research of the properties of actived carbon, limestone and peat because of these substances have been used for the water treatmet by filtration thanks their efficiency and lower cost in relation to conventional treatment systems such as screening and sedimentation. Laboratory tests were carried out following their respective regulations, which helped us to determine the granulometry, maximum nominal size of particles, coefficient of uniformity, coefficient of curvature, coefficient of compactness, porosity, sphericity and permeability. For the preparation of the permeameter plans, the AASHTO T 215 – 70 standard was followed, wich refers to permeability of granular soils, and the Autocad 2019 program was used both for presentation of plans and 3D modeling.

    Diseño de un sistema experimental de pruebas en columna para el análisis de sustancias reactivas en condiciones dinámicas para el tratamiento de aguas residuales

    For the accomplishment of this project, we identify the type of reactive material for the media filter, considering the nominal and critical size of sand, as a starting point to determining the design of the length and diameter of the column, obtaining the minimum length of the thickness for the reactive material in the filter based on preliminary studies, for the system to works at its maximum capacity; subsequently, where all the necessary information for the column design was collected, the corresponding necessary flow calculations were made based on the filtration rates, recommended by several authors, and therefore we use the design parameters of a rapid filter due to a greater efficiency obtained in pollutants removal and shorter system operating time. In order to validate the design of the experimental column test system, a filter medium maintenance system was incorporated when required, for which a pumping and piping system was selected to guarantee its cleaning. After the design stage, the column test system was modeled using SolidWorks software due to the ease of generating accessories and materials necessary for assembly and showing in detail the process that leads to the construction of the system.
