A fluid handling apparatus includes a body, which comprises a fluid handling structure, and a flexible membrane attached to the body and formed to interact with a fluid in the fluid handling structure, wherein the membrane comprises a first actuation component. A second actuation component is provided, wherein the first and the second actuation component are formed such that the same attract or repel each other in a first positional relationship, in order to actuate the flexible membrane. A driving means is provided to move the body relative to the second actuation component, in order to bring the first and the second actuation component into the first and out of the first positional relationship.

Fluid handling apparatus and method of handling a fluid

A particle sedimentation apparatus includes a rotation body rotatable about a rotation axis and a separation chamber formed in the rotation body, to cause sedimentation of particle suspension in the separation chamber upon rotation of the rotation body. The particles accumulate in a radially outward region of the separation chamber. A flow-rate-determining inflow channel having azimuthal path length with an inflow channel inlet and an inflow channel outlet is formed in the rotation body, the inflow channel inlet being arranged radially further inwardly than the inflow channel outlet, the inflow channel outlet being fluidically connected to the separation chamber and formed to introduce particle suspension into the separation chamber upon rotation of the rotation body. Furthermore, an outflow channel is formed in the rotation body with an outflow channel inlet and an outflow channel outlet, to at least partially drain supernatant liquid formed by sedimentation from the separation chamber.
