## Abstract

Disclosed is an electrostatic field water treatment apparatus comprising: a high voltage unit to which a high voltage is to be supplied, and an earth ground unit connected to an earth ground and used as a pipe through which water is to pass, wherein the high voltage unit is disposed at a central part of the earth ground unit and comprises a high voltage insulation cable to which a high voltage is to be supplied and an electrode case configured to cover the high voltage insulation cable and consisting of an insulator.

## Claims

### Claim 1

An electrostatic field water treatment apparatus comprising:
a water inlet fixing member coupled to a pipe into which water is to be introduced;
a turbo generator fixed to the water inlet fixing member and configured to generate electricity;
an electrostatic field water treatment unit configured to remove bacteria or scale included in the water introduced through the pipe by using a high voltage;
a fixing unit coupled to the electrostatic field water treatment unit and fixed to an output unit of the turbo generator;
a high-voltage converter configured to change a voltage generated at the turbo generator into a high voltage;
a filter disposed at a rear end of the electrostatic field water treatment unit and configured to filter the water having passed through the electrostatic field water treatment unit;
a water outlet fixing member coupled to a pipe through which the water is to be discharged, and
a main body configured to cover the turbo generator, the electrostatic field water treatment unit, the fixing unit, the high-voltage converter and the filter disposed between the water inlet fixing member and the water outlet fixing member,
wherein a direction of the water inlet fixing member and the water outlet fixing member forms a straight line,
wherein the electrostatic field water treatment unit comprises a high voltage unit comprising a high voltage insulation cable to which the high voltage is to be supplied, a pipe coupled to an upper part of a rear end of the fixing unit, through which water is to pass and which is covered by the high voltage insulation cable, and an earth ground unit disposed in the pipe, formed to have a rod shape and connected to an earth ground,
wherein a part of the pipe covered by the high voltage unit is formed of an insulator,
wherein the insulator is formed of any one of glass, polyethylene, polypropylene, PVC and Teflon,
wherein the high-voltage converter is disposed at the rear end of the fixing unit and next to the electrostatic field water treatment unit.
