Abstract: A floating cell with a floating macrophyte filter that can be installed in a chamber containing a volume of fluid to be filtered. The cell has: a layer with a floating macrophyte filter between a perimeter and a centre of the island; supporting means with peripheral structural means for defining a periphery; internal structural means for defining a framework; a central node; peripheral connecting means; internal connecting means; central flotation means and peripheral flotation means.

Abstract: The invention relates to a floating assembly structure with independent support, intended for securing containers or substrates for floating plant species crops. The structure is shaped like a flat polygon with at least three sides and has at least two elements for assembly with other floating assembly structures, such that a meshed system can be formed on the surface of the water by assembling multiple structures to one another. Furthermore, the structure includes a plurality of coupling bars for securing the aforementioned containers and is configured to withstand the forces and moments generated by the movement of the water and by the growth of the plants.
