Filtering method for swiming pools with water flow rate multiplying unit

Abstract

This invention relates to a filtration process for swimming pools, to a water flow multiplier for the implementation of this process and to the swimming pools thus designed. According to this invention, at least a portion of the return water flow of the circulation pump (10) is sent in at least one flow multiplier (30), consisting essentially of a convergent tuyere followed by a divergent tuyere with, at the intermediary location, an admission (29) of said return water flow of the pump, of which the entrance on the side of the convergent tuyere communicates with at least one admission (23) of the water to be filtered coming from the swimming pool and which goes through a filter (31) suitably set upstream from this entrance, and of which the exit on the side of the divergent tuyere opens to the pool forming return (33).
