ABSTRACT:
A unitary package for water treatment for attachment to a home hot water heater which is adapted to be easily serviced and readily monitored by the homeowner. The water treatment device is an electrical device especially adapted for separating magnetic particles such as iron particles in feed water pipes to home hot water heaters and the like. The basic structure comprises an electromagnetic coil energized by household line voltage which completely encircles the inlet pipe. The inside of the inlet pipe is fitted with special bearings which support a solid helical impeller which rotates only when water flows through the pipe. The helical impeller is made of ferromagnetic material and is fitted to a very close tolerance to the wall of the inlet pipe thereby sweeping in a broom fashion the inner wall free from particles which tend to deposit on the wall. The electromagnetic unit is a separate part of the package and is completely contained within a housing. The helical impeller with its shaft traverses the entire length of the electromagnetic coil. The shaft of the impeller is supported on long life bearings mounted within the inlet pipe at each end of the electromagnetic coil so as to produce a high flux density and field intensity surrounding the blades of the helical impeller. The package unit and pipe can be easily fitted by the homeowner into the city water line.
