Abstract

Un sistema de purificación de agua de alimentación por gravedad que comprende una unidad de filtración adaptada para filtrar material particulado y una unidad purificadora química que contiene un agente purificador químico, en donde la unidad purificadora química está alojada en una cámara sellada y se encuentra en comunicación fluida con la unidad de filtración, de modo que el agua tratada por la unidad de filtración se alimenta luego por gravedad hacia la unidad purificadora química y es retenida allí durante un período determinado, después del cual el agua abandona el sistema a través de un medio depurador adaptado para recuperar el agente purificador químico lixiviado. El sistema asegura la distribución de agua microbiológicamente pura de alta calidad, a la vez que mantiene la simplicidad y ventajas de los sistemas de filtración alimentados por gravedad.A gravity feed water purification system comprising a filtration unit adapted to filter particulate material and a chemical purifying unit containing a chemical purifying agent, wherein the chemical purifying unit is housed in a sealed chamber and is in communication fluid with the filtration unit, so that the water treated by the filtration unit is then fed by gravity to the chemical purifying unit and is retained there for a certain period, after which the water leaves the system through a medium scrubber adapted to recover leached chemical purifying agent. The system ensures the distribution of high quality microbiologically pure water, while maintaining the simplicity and advantages of gravity-fed filtration systems.
