An apparatus for conditioning an aqueous liquid includes at least one inlet, at least one liquid treatment device for the treatment of liquid by ion exchange including a cation exchange material of which at least a portion is in the hydrogen form, a membrane filtration device and a section arranged to process filtrate produced by the membrane filtration device. This section includes a liquid treatment device for dissolving at least one mineral contributing to carbonate hardness in water into at least some of the liquid passing through the section. At least one of the at least one inlets is connected to an inlet of the membrane filtration device via at least one of the at least one liquid treatment devices for the treatment of liquid by ion exchange.

Apparatus and method for treating an aqueous liquid

A container for the filtration of liquid is described, which has a cup and a cover mounted on the cup. The cup is at least partly filled with a filter material and has at least one outlet window for the liquid. The cover has at least one inlet window and at least one outlet window for air, wherein at least the windows have lattice-like structures with lattice openings. The air outlet window has at least one recess extending inward from the plane of the window, which is provided at least partially with at least one lattice structure.

Container for filtering liquid having an outlet aperture for air

A device for sterilizing water, comprising a UV lamp, at least one vessel through which water flows, an inlet and an outlet, a reaction chamber being arranged in said vessel. The outlet of the container forms a free down spout. The UV lamp and the vessel are arranged in a cartridge, the cartridge comprising at least fixing means for detachable fixing to a connection device, and connection means for supplying the current and water from a connection device.
