Abstract
An apparatus for imparting an electric field to water travelling within a pipe. The apparatus includes a plurality of rectangularly-shaped coils of electric wire connected in an electrically parallel arrangement. Each coil is sandwiched between flexible cover sheets. The resulting assembly is applied to the outer circumference of the pipe, with the lengthwise dimension of the coil extending perpendicularly to the flow inside the pipe. A time-varying electric current is applied to the coil to produce a corresponding electric field. This, in turn, produces controlled precipitation of mineral ions from the water.
