FLORIDA – CLEARWATER ENVIRO TECHNOLOGIES has a cost-saving, non-polluting alternative to costly chemical de-scaling of large-diameter pipelines, valves, pumps and other mining equipment exposed to hard water. It has added seven new models to its ScaleBlaster line of electronic de-scalers. They can handle standard diameters of non-steel pipe from 12 to 40 inches and steel pipe from four to 26 inches.

Industrial ScaleBlaster units operate like those designed for commercial- or residential-size pipe. A microprocessor in the control unit sends out a square-wave current that rapidly sweeps a range of select frequencies. Carried by signal coils that wrap multiple times around an upstream pipeline, this current induces a dynamic electromagnetic field perpendicular to the water stream that forces calcium carbonate (the mineral mainly responsible for scale) to come out of solution as soft, non-adhesive, submicron particles. These remain suspended in the water and flow harmlessly through the system.

Removal of already-existing scale comes as the necessary byproduct of this scale-prevention process. The radical reduction in calcium-carbonate hardness yields a corresponding increase in water solvency, so that existing scales of calcium carbonateand now other mineralswear away and do not return.

Test results and technical information for the ScaleBlaster is available at www.ScaleBlaster.com. Or contact Rodney Janelle at 800-756-7946 or h2ospace@aol.com.
