    Obtención de coagulantes/ floculantes orgánicos a partir de extractos naturales y evaluación de su potencial como coadyuvante en el proceso de tratamiento de agua
    (Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Maestría en Química, 2022) Poveda Ocaña, Rebeca Abigail; Villasana Aguilera, Yanet Tibaire
    The scarcity of drinking water in several countries and areas represents a problem on a global scale, where conventional methods with polyaluminum chloride are used in the coagulation and flocculation processes in water treatment. These processes generate residual sludge, which may contain high levels of aluminum and cause harm to humans and the environment. It is currently important to generate new ecological and easily accessible alternatives to improve water quality. For this reason, the purpose of this research was to obtain organic coagulants, and to evaluate their usefulness as a coadjuvant for polyaluminum chloride in the water treatment process. The project was developed through biomass extraction processes, which was evaluated through partial- total substitution tests and physical-chemical analyzes of the water samples treated with this chemical-organic combination. The results were processed with statistical analysis tools to determine the requirements to be used as an co-adjuvant, such as: yield percentage in the extraction process, its availability in the medium, removal percentage, economic yield. Considering the current environmental regulations in the country, detailed in the Unified Text of Secondary Environmental Legislation.
