Abstract
A 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.
Claims15
A fluid treatment apparatus, comprising:
- an elongate tubular duct having an inlet port and an outlet port at, or adjacent to, its opposite ends;
- an elongate light source extending along an axis of said elongate tubular duct;
- and,
- a guide vane extending helically along an internal wall of the elongate tubular duct between input and output ducts, with apertures being formed in the guide vane for communicating between adjacent turns of fluid flow passage defined by the guide vane.
