<p>The equipment has an enclosure (2) extending parallel to a level of water surface (L). The enclosure has an accumulation screw (5) for partitioning contiguous portions of water and fluid. The screw has an axis equipped with a central core (5a), where the axis is located at the level. The screw has an external diameter decreasing gradually from an inlet (A) to drains (E, O) to reduce a free surface of the partitioned portions. Each partitioned portions are locked up in a U shape channel of which a free surface of partitioned portions separate volume of water into two parts.</p> |
