1. A method for producing from a first fluid having particles of a substance suspended or dissolved therein with a first concentration of said substance, a second fluid having a second concentration of said substance lower than the first concentration and a separated-fluid product, in which concentration of said substance is greater than that in the first fluid, the method comprising:
providing a separation duct having a geometry suitable to receive and pass therethrough a fluid including aggregates of a predetermined range of sizes so as to produce from said fluid said second fluid and said separated-fluid product, said separation duct including a bay portion extending at least partially along a curved central line defining a fluid flow direction, said bay portion comprising a main channel and at least one bay channel at least partially coextensive with the main channel, the at least one bay channel having, in a cross-section of the bay portion taken perpendicularly to said central line, an area which is smaller than an area of the main channel in said cross-section;
producing a pre-treated fluid comprising aggregates of said sizes formed from a part of said particles and a remaining part of said particles, by pre-treating said first fluid;
feeding said pre-treated fluid into said separation duct and letting said pre-treated fluid pass therealong so as to produce from said pre-treated fluid said second fluid and said separated-fluid product;
wherein producing said separated-fluid product comprises accumulating at least some of the remaining part of said particles within the at least one bay channel.
