1. A PEF (pulsed electric field) chamber intended for treating a flow with electric field pulses, said PEF chamber comprising:
a PEF treatment tube; and
opposite electrode units,
wherein each one of said opposite electrode units has one flow receiving end and one flow exit end,
wherein the PEF treatment tube comprises exit flow portions arranged subsequent to the flow exit ends of the electrode units in an intended flow direction, and thus functioning as an extension of the opposite electrode units in the intended flow direction,
wherein the opposite electrode units are longitudinal,
wherein the flow receiving ends are rounded in the intended flow direction into the PEF treatment tube,
wherein the exit flow portions are rounded in the intended flow direction,
wherein the opposite electrode units are arranged in the PEF treatment tube to provide a first geometrical narrowing at the flow receiving ends, and
wherein the exit flow portions of the PEF treatment tube are arranged to provide a second geometrical narrowing subsequent to the flow exit ends.
