<p>The invention relates to filters for treatment of a rain outflow. A filter comprises a ferroconcrete frame (1), in which is disposed removable metal cassette (2) filled with absorptive layered load (3, 4), layers of which are portioned by metal grid with perforations (5) ¿< 1 mm, removable cover (6), metal grid with ¿ 30-50 mm (7) and < 2 mm (8), inlet pipe (9) and an outlet pipe (10). A cassette (2) is made with fenestrate sides (1/4 part) and a bottom. An upper layer of a load is made from natural mineral adsorbent (vermiculite) (3) for treatment of rain outflow from organic compounds (petrol products), a lower part of a load is made from natural zeolite (4), consisting clinoptilolite 65 - 75 % and mordenite 20 - 30 % of sorption materials of activate metal ions.</p> |
