摘要

A device for filtration of a liquid substance, comprising: - at least one filter element (8), through which liquid is intended to be sucked from the liquid substance in order to obtain a filtrate; - at least one vacuum generating fall tube (12), through which filtrate is arranged to fall in order to generate an underpressure required for sucking liquid from the liquid substance through said filter element (8); and - a turbine (17) provided in a lower part (18) of the fall tube (12), this turbine (17) being configured to be driven by the filtrate falling through the fall tube (12) in order to recover energy.
