Abstract

An apparatus and method for electrolytically treating water which can include the influent inlet arrangements for cavitation and one or more pairs of electrodes. The electrodes can be suitable for a continuous anodic and cathodic operation for treating water. The pressurized influent premixed with oxidant gas, such as, but not limited to, Ozone or Oxygen can be pumped into the reactor vessel through the mixing nozzles preferably arranged radially along the circumference. A power source for each reactor provides voltage and current to the electrodes. The controller maintains the voltage and current to the electrode. The duration of each voltage polarity applied to each electrode can be preferably the same. The polarity of the voltage to the electrode can be periodically reversed at a set interval.
