  • Process and apparatus for the control of undesirable organisms in a water system
    Patent number: 7169310
    Abstract: There is described a process for the treatment of water to prevent the survival of unwanted organisms in said water. The process is based on the supply of gas into the water at pressures greater than 1 atmosphere, while ensuring that the mass transport of gas into the water is greater than the mass loss across the air-water (surface) interface, i.e. such that a gas super-saturated condition is established. Further, there is described an apparatus or system for the treatment of a body of water, i.e. to prevent the survival of organisms in said water. A preferable embodiment comprises a compressor which delivers a compressed gas to said water system in an amount sufficient to establish a supersaturated condition in said body of water.
