<p>The subject of the invention is a biofilm support component intended to be immersed in a biological water purification reactor, comprising a tubular envelope having two end openings that communicate with each other via a channel, said envelope having an inner surface delimiting said channel and an outer surface, said envelope having a series of corrugations that form deformations of said inner surface and of said outer surface, characterized in that said envelope has a length less than or equal to 15 mm and in that the volume of said corrugations that form deformations of said inner surface (131) and the volume of said corrugations that form deformations of said outer surface (132) each represent between 20 % and 29% of the total volume of said envelope.</p> |
