EQUIPO DE DEPURACION DE AGUAS RESIDUALES DE CENTRALES HORTOFRUTICULAS Y TRATAMIENTOS FITOSANITARIOS EN CAMPO

Un depósito filtro donde se realiza una etapa de pretratamiento. El depósito es un decantador aque se puede añadir floculante, mezclandose uniformemente con un agitador. Los fangos se extraen enviándolos a una bolsa filtrante pasando los permeados a un depósito de recogida, de donde se bombea al mismo depósito que recibe al agua clarificada. De este depósito se trasiega, pasando por un filtro de seguridad, a una batería de columnas de carbón activo donde se depura por absorción hasta alcanzar los valores límites establecidos. Said equipment includes a tank-filter (1, 15) in which a pretreatment stage is carried out. The tank (1) is a decanter to which a flocculant that is uniformly mixed with an agitator (3) can be added. The sludge is removed by delivering it to a filter bag (5). The permeates are then fed to a collecting tank (6) and pumped to the same tank (7) receiving the clarified waters. The permeates are then decanted from said tank (7) through a safety filter (8) to a battery of activated carbon columns (9) where they are purified by adsorption until the established threshold values have been reached. In another embodiment, the reservoir-filter (15) is a polypropylene bag filter with diatomaceous earth, wherein the liquid passes directly to the decanting tank and is then pumped to the battery of activated carbon columns (9).
