The invention relates to a process and a device for enriching water, in particular drinking water, with magnesium ions. In order to enable enrichment of water with magnesium ions in exchange for calcium ions and/or heavy metal ions during treatment of water, and in particular of drinking water, it is proposed according to the invention to pass the water through an ion exchanger which contains a weakly acidic ion exchange material, wherein at least a part of its ion exchange capacity is loaded with magnesium ions.

A liquid purification system includes a system raw liquid feed unit and a filtration unit, which includes a liquid concentration device having an internal partition dividing a variable volume collection cavity for raw liquid coming from an initial stage of liquid filtration and for mixing therein concentrate and a raw liquid displacement cavity. The cavity is connected to a secondary line that supplies raw liquid to the cavity to displace concentrate from the collection cavity and to recycle raw liquid from the displacement cavity through the secondary line under pressure exerted by concentrate and raw liquid in the collection cavity. A filtration unit provides long-term contact between raw liquid and concentrate in the variable-volume collection cavity to provide smooth increase in the concentration of liquid supplied to a liquid purification device.

An aerator for treating wastewater is configured to produce air bubbles to mix and circulate wastewater within a treatment facility. Additionally, the aerator is configured to inject additive into the wastewater at the same time as the air bubbles are being produced, so that roiling of the air bubbles and/or circulation induced by the air bubbles rising within the water column facilitates mixing of the additive with the wastewater.
