EQUIPMENT FOR PURIFYING RESIDUAL WATERS FROM HORTICULTURE AND POMOLOGY CENTERS AND IN SITU PHYTOSANITARY TREATMENT
摘要
<p>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). <IMAGE></p>
