Presentation
BIOTRADE designs and manufactures in France a complete range of fine-bubble diffusers and associated aeration grids/frames for efficient oxygenation of wastewater.
BIOTRADE diffusers, fine and medium bubble, are designed to oxygenate and mix wastewater in treatment basins. Compressed air is injected into air headers, then released through diffusers, tubes, discs or panels positioned at the bottom of the basin. The bubbles rise to the surface, ensuring oxygen transfer to micro-organisms and homogenisation of the basin.
Our solutions are suitable for all types of basins, whether new or under rehabilitation, and provide optimal energy efficiency.
