Abstract
A method as well as a liquid mixing system provide a liquid-foam mixture by mixing water with at least one additive. The liquid mixing system includes a water pressure source, an additive reservoir unit, an air compressor unit with a compressor and a drive device, a first and second mixing device, a discharging unit, and multiple different line networks for the respective media. The drive device is formed by a water engine or a water turbine, the water inlet of which is line-connected to the water pressure source.
