SURFACE WATER POTABILIZATION SYSTEM BY MEANS OF A COMPACT COAGULATING/FLOCCULATING-SETTLER TANK HAVING RECIRCULATION OF FLOCS, A BATTERY WITH CLOSED FILTERS AND A TANK HAVING AN AUTOMATIC BACK-WASHING PROCESS BY A SIPHON

The present invention refers to a complete surface water potabilization system for disinfecting and removing colour and cloudiness from water. The invention simplifies and reduces the processes provided by common systems intended for the aforesaid purposes, the same including a low energy consumption; the use of a reduced number of equipments; a simplified automatic operation. The invention is a novel and totally different system from those currently available on the market, which also includes a quick mixing system, coagulation, flocculation, setting, a recirculating process in a single compact equipment without requiring engine mechanical elements; a water flow passing through filters by means of gravity and a back-washing process by gravity as well. Esta invencion se refiere a un esquema completo para la potabilizacion de agua superficiales para la eliminacion del color y turbiedad, seguida de una desinfeccion. Compacta y simplifica los esquemas comunmente usado para este tipo de tratamiento en los siguientes aspectos. - Muy bajos costos de energia; - Utilizacion de un minimo de equipos; - Operacion automatica muy simplificada. Se trata de un esquema novedoso y totalmente diferente a los que actualmente se utilizan. De la misma forma son parte integrante del esquema y contribuyen a su simplicidad y abaratamiento de costos: - El sistema de mezcla rapida, coagulacion, floculacion, sedimentacion, recirculacion en un solo equipo compacto, sin elementos mecanicos movidos por motores. - El paso a traves de los filtros por gravedad; - El retrolavado igualmente por gravedad.
