Abstract (en)
[origin: WO2021219345A1] The invention discloses a system (1) and a method for operating such system for supplying gas bubbles (500) into a fluid (300). The system comprises a longitudinal cylindrical fluid pipe (200) for the fluid (300) to pass therethrough, a turbulence inducing device (400) arranged within the longitudinal cylindrical fluid pipe (200) for generating a turbulent flow of the fluid (300) and a gas supplying device (100). The gas supply device comprises an outer surface (102) and an inner surface (104) enclosing a toroid shaped chamber (101),a gas inlet (106) configured to feed gas into the toroid shaped chamber (101) and a membrane (110) arranged at the inner surface (104), the membrane (110) being configured to allow gas to pass from the toroid shaped chamber (101) into the flow of fluid (300) as gas bubbles (500). The gas supplying device (100) is arranged upstream relative to the turbulence inducing device (400) such that the turbulent flow of fluid (300) passes a cross-sectional area (600) enclosed by the membrane (110) when passing the turbulence inducing device or immediately after exiting the turbulence inducing device (400).
