The unique double-flow principle of the JUWEL Bioflow filter system ensures that different flow velocities are achieved in the filter and thus contributes significantly to the exceptionally high filter performance of the Bioflow system.
A comparatively fast flow velocity is particularly advantageous for mechanical and chemical filtration in the upper filter area.
A slower flow velocity in the lower part of the filter, on the other hand, favours the optimal development of anaerobic bacteria, which are essential for biological filtration.
