DEVICE AND SYSTEM FOR FILTERING EFFLUENTS FOR HORTICULTURE OR MARKET GARDENING

摘要

The invention concerns a device for filtering (1) polluted effluents, comprising an inlet (2) for receiving the polluted effluents to be treated and an outlet (3) for delivering the effluents filtered by the device (1), the filtering device (1) including a series of successive filters. Said device comprises a first filter (4) whereof the cut threshold is of the order of 1 micron, a second filter (5), having a filtering medium whereof the cut threshold ranges between 1 and 0.5 micron and a third filter (6), the cut threshold of that third filter being less than 0.5 micron, said filtering device (1) thereby enabling elimination of all traces of threadworms or pathogenic microscopic fungi contained in the polluted effluents derived from the soilless cultivation of horticultural or market gardening operations (7) by means of three filters (4, 5, 6) having substantially homogeneous life spans.
