<p>The invention concerns a water circulation device for decorative ponds. Said device is designed to create in the pool favourable conditions for producing a sustainable biological balance and for contributing to the mechanical cleaning of the pond so as to prevent clogging. The device consists of various elements, some of which are integrated in the pond structure: a network of galleries (7) for distributing the collected deep water, one or several collecting compartments (9), overflow channels (10) for cleaning the surface of the water body, a biological filtration pond (1), a drainage network (3) located in the filtration pond under a filtering mass (2), a pumping section (4) connected to a pumping device (5).</p> |
