the flotation-filter unit. As the same velocities prevail in a conventional flotation unit and in a filter (5-12 m · h 1), the idea was conceived to use the lower part of the flotation unit as the top of a filter (figure 34): instead of the traditional cell floor, a filtering medium would be laid over a floor equipped with nozzles; a regulation mechanism would be fitted to the filter water ...
