Abstract

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.
