<p>The device (100) comprises a first tank (110) for recovering washing water, a second tank (120) connected to the first tank by a channel (151) for gravity flow, a filter that is placed between the first and second tanks and connected with trays, a perforated basket suspended in the second tank, a drainage channel flowing into the basket, a third tank (130), units for contacting the third tank with the second tank, a water suction unit contained in the third tank, and a unit for covering an opening of a chest tank. The device (100) comprises a first tank (110) for recovering washing water, a second tank (120) connected to the first tank by a channel (151) for gravity flow, a filter that is placed between the first and second tanks and connected with trays, a perforated basket suspended in the second tank, a drainage channel flowing into the basket, a third tank (130), units for contacting the third tank with the second tank, a water suction unit contained in the third tank, and a unit for covering an opening of a chest tank. The second tank is separated, by a permeable partition, into two volumes that are vertically stacked. The filter is placed on a permeable wall, and is constituted of a polypropylene needle felt. The contacting units are located below a level of the permeable wall. A diameter of pore of the filter is 50 mu m. The second and third tanks are constituted by the chest tank comprising a partition. The channel is constituted of assembled sections to be contained in the chest tank.</p> |
