An object of the invention is to provide a method for preventing scale deposition that can prevent deposition of calcium fluoride scale without increasing phosphorus concentration in a fluorine-containing water system. The added chemicals separate the silicone emulsion waste into silicone oil and an emulsion-free water. \u201cI\u201d core coil may be driven by AC power, pulsed andor DC power or audio power. The energy recovery unit is coupled between the X-side of the panel capacitor and the Y-side of the panel capacitor for charging and discharging the panel capacitor. The systems and methods may compress the filtered signal with a first compressor, process the signal with a graphic equalizer, and compress the processed signal with a second compressor.
