• Acid Mine Drainage Treatment

     · The next step in the treatment process is the thickening step – settling and removing the nonsoluble iron from the liquid. For optimal performance, the thickener should be sized between and GPM per square foot. It is ideal to use a variablefrequency drive (VFD) to power the rake arms, allowing you to slow the rakes down as necessary.
