A BIOPROCESS FLUID MIXING SYSTEM
Abstract:
A bioprocess fluid mixing system (3; 3′; 3″; 103; 103′), said fluid mixing system (3; 3′; 3″; 103; 103′) comprising: —at least two fluid inlets (5a, 5b, 5c, 5d, 5e), configured for providing a first fluid into the fluid mixing system through a first fluid inlet (5a) and for providing a second fluid into the fluid mixing system through a second fluid inlet (5b); —at least one valve arrangement (13a, 13b, 13c, 13a′), where a first valve arrangement (13a; 13a′) is in fluid communication with at least both the first fluid inlet (5a) and the second fluid inlet (5b); —at least two pumps (11a, 11b, 11c, 11d, 11e), where a first pump (11a) is in selective fluid communication with at least both the first and the second fluid inlets (5a, 5b) via the first valve arrangement (13a; 13a′) and a second pump (11b) is in fluid communication with at least one of the first and second fluid inlet (5b); and —a common fluid outlet (14) which is in fluid communication with both an outlet (15a) of the first pump (11a) and an outlet (15b) of the second pump (11b), wherein pump rates of the at least two pumps (11a, 11b) and valve positions in the at least one valve arrangement (13a; 13a′; 13b, 13c) are configured to be controllable by a control system (21) such that mixing of at least a first fluid from the first fluid inlet (5a) and a second fluid from the second fluid inlet (5b) can be performed to a requested mixing of the at least two fluids and to a requested combined fluid flow rate at the common fluid outlet (14).
