Abstract:
1. An improved electrocoagulation (“EC”) treatment process, for treating waste water, comprising: providing a variable power supply that outputs an alternating current (“AC”), the variable power supply being adjustable from 0 to 480 volts alternating current (“VAC”) in response to the EC treatment process; connecting a variable step down transformer with a multiple tapped secondary winding to the variable power supply; using the variable step down transformer to pass the AC current output provided by the variable power supply to a rectifier, the variable step down transformer being independently adjustable in response to the EC treatment process; rectifying the output of the variable step down transformer from AC to direct current (“DC”); delivering the rectified DC current to at least one EC treatment cell having a plurality of sandwiched plates, for use in inducing electrocoagulation in the waste water; using the rectified DC current delivered to the EC treatment cell to create alternating positive and negative charges on the sandwiched plates; and passing the waste water across the sandwiched plates within the cell and periodically reversing polarity of the sandwiched plates as waste water is passed across the plates.
