Abstract

La presente invención propone un "sistema de eliminación de metales pesados en aguas mediante microalgas", que utiliza las propiedades de estos microorganismos como material adsorbente y favorecedor de procesos de oxidación y precipitación, y una secuencia de etapas adecuadamente diseñadas para el funcionamiento óptimo del sistema. El proceso propuesto implica dos etapas claramente diferenciadas, la primera de producción en continuo de microalgas y la segunda más novedosa de puesta en contacto del cultivo de microalgas con las aguas de mina mediante sistemas de retención o recirculación de lodos. De esta forma se minimiza la cantidad de microalga necesaria, permitiendo depurar grandes volúmenes de agua contaminada por unidad de volumen de cultivo de microalgas.The present invention proposes a "system of elimination of heavy metals in waters by means of microalgae", which uses the properties of these microorganisms as adsorbent material and favors oxidation and precipitation processes, and a sequence of stages properly designed for the optimal functioning of the system . The proposed process involves two clearly differentiated stages, the first one of continuous production of microalgae and the second most novel of bringing the microalgae culture into contact with the mine waters through sludge retention or recirculation systems. This minimizes the amount of microalgae needed, allowing to purify large volumes of contaminated water per unit volume of microalgae culture.
