PCT No. PCT/GB94/02178 Sec. 371 Date Apr. 5, 1996 Sec. 102(e) Date Apr. 5, 1996 PCT Filed Oct. 6, 1994 PCT Pub. No. WO95/09815 PCT Pub. Date Apr. 13, 1995A water sterilization system comprises an electrostatic water treatment apparatus (10) having its outer duct (13) connected to an ultraviolet treatment apparatus (11). The outlet duct (14) of the ultraviolet water treatment apparatus (11) is connected to an apparatus (12) which aerates the treated water with ozone gas. The electrostatic field of the apparatus (10) varies along the axis of the flow duct, so as to increase the speed at which dissolved minerals precipitate out of solution. The ultraviolet treatment apparatus (11) has a slotted helical guide vane, which creates a turbulent flow of water and ensures that large clumps of microorganisms are broken up. The ozone gas is generated in an apparatus (15) by exposing water vapor and air to shortwave UV radiation. |
