Low frequency waveforms are emitted through two coiled wires attached to the outside of the water pipe. As a result of
these waveforms, the two coils are constantly inducing a voltage into the water in the area of the ClearWave™. When
one coil induces a positive voltage the other coil induces a counteracting negative voltage. This electric field causes the
calcium or magnesium to remain in solution or suspension and the treated water continues to dissolve scale as it flows
downstream. Over time, the ClearWave™ treated water helps solve hard water problems in the entire system, including
pipes, water heaters, showerheads, and appliances. The ClearWave™ is the state-of-the-art in electronic water
conditioning. The ClearWave™ microprocessor-controlled technology continually varies its frequency, affecting the
widest range of mineral concentrations and other variables that cause “hard water” problems.
The length of time required to alter the characteristics of the lime scale is dependent on the mineral makeup of the water
being treated. The mineral makeup of the water can impact the operation of the ClearWave™’s electrical field. A high
concentration of iron (soluble and insoluble) causes a disruption and weakening of the electrical field, reducing the
effectiveness on scale reduction. Under these conditions an iron removal system is required to filter out the iron prior the
ClearWave™. Additionally, if the water is excessively hard (greater than 25 grains), the ClearWave™ is often less
effective.
TESTING FOR HARDNESS AND IRON LEVELS
High Iron Concentration
A high concentration of iron (soluble and insoluble) causes a disruption and weakening of the ClearWave™’s electrical
field, reducing its effectiveness on scale reduction. Under these conditions an iron removal system is required to filter out
the iron prior to the ClearWave™. We recommend an iron removal system for total iron levels above 0.3 ppm (parts per
million). Contact your local health department or water authorities for testing your water
Water Hardness
On hardness levels above 250 ppm or 15 gpg, two ClearWave™ units should be mounted in series on the incoming water
pipe. The maximum hardness level the ClearWave™ will effectively work on is 425 ppm or 25 gpg. Above these levels,
the ClearWave™ should be used in conjunction with a tradition ion exchange water softener to remove hardness and
condition the water. This allows you to minimize the salt used to remove the hardness and maintain the cost saving
benefits of the ClearWave™ water-conditioning system.
