Abstract
The device provided relates to the field of water purification and disinfection. The device for water purification works by exposing water to an hydroxyl radicals and includes a corona discharge reactor, an ejector, at least one solenoid valve, control electronics, a mixing chamber. Inside the reactor there is a group of pin discharge electrodes, an earthen solid electrode, a chamber of saturated vapors of treated water, and the reactor is interfaced to the ejector. The device allows to obtain at the output of the device water with a high degree of purification, as from biological pollution, as well as to get rid of many undesirable chemical compounds present in the source water by their oxidation to safe products.
