Abstract: An apparatus for treating a liquid; such as water or a beverage, in order to improve the quality of the liquid, and in order to ensure that the minerals and nutrients which are naturally present in the liquid are assimilated in a living organism consuming the liquid to the maximum extent. At least two pipe segments are twisted about a common axis in such a manner that each of the pipe segments at least substantially abuts said common axis. Each pipe segment has an inlet opening and an outlet opening, and the pipe segments forms parallel flow paths between a common inlet and a common outlet. The liquid performs spiraling movements when flowing through the pipe segments, and thereby the minerals in the liquid are forced to be in a more absorbable form.
