Abstract

Hydro-cyclone for oxygenating water is driven so that an underpressure is established in the cyclone. This sucks in air so it mixes with water in the cyclone. Preferably the cyclone is an inverted cone with air being sucked in through its narrow end. Also claimed is a water recycling facility including a hydro-cyclone as above.
