Abstract

The paper presents the dependence of copper and silver ions formation on the duration of voltage pulses of diaphragm electric discharge and on the pH of treated liquid medium. Knowing it allows one to create an automatic control system to control bactericidal agent's parameters obtained in diaphragm electric discharge reactor. The current-voltage characteristic of the reactor with a horizontal to the diaphragm membrane water flow powered from the author's custom pulse voltage source is also presented. The results of studies of the power consumption of diaphragm electric discharge depending on temperature of the treated liquid medium are given.

Highlights

Electric discharge water processing technologies both in industry and in everyday life are increasingly used
The Diaphragm electric discharge (DED) water treatment technology described in [8] consists of the special switching power supply (SPS) and the reactor [9] divided by a diaphragm membrane into two chambers, each of them being equipped with metal electrodes and nozzles
The current-voltage characteristics (CVC) of the DED reactor powered by the SPS with bipolar pulses are highly nonlinear and has a crescentshaped character
