Abstract: A system comprises a water purification system having an electrolytic cell to receive a flow of waste water. A power source supplies power to the electrolytic cell. The power source at least comprises an H-bridge controller to apply power to the electrolytic cell. A device senses an amount of current being supplied to the H-bridge controller. An analog-to-digital device outputs a digital signal representative of the sensed current. A processor processes the digital signal and outputs a plurality of pulse width modulated control signals for the H-bridge controller. The control signals control the H-bridge controller to apply the power during a first period of time with a current in a first direction to maintain an average for the sensed current, and to apply the power during a second period of time with the current in a second direction to maintain the average.
