Gravity Aerator - The Scientific Basis

The Newton Gravity Aerator is based on over 20 years research by Claude Dyson and a team of researchers at John Moore University in Liverpool. The research focused on air entrainment and oxygen transfer in a Co-Current Downflow Contactor (the technical name for this type of aerator). Two PhDs have been awarded for research peripheral to the design of this aerator for which patents have been granted and others applied for in Europe and USA.

This aerator utilises the impact of a relatively slow speed jet of water flowing down the wall of a tube standing in a greater expanse of water to encapsulate air as discrete bubbles, and to carry the mixture down to the lower end of the tube. Oxygen and nitrogen dissolve from the bubbles into the water during their descent.
