Experimental Facility

Abstract

Several experimental installations have been developed at the IEE RAS for investigation of the PED parameters in water and the WDN electrophysical and chemical properties. Installations for electrodischarge treatment of water are various both in characteristics of electric pulses and in their productivity (maximal productivity of such installations is 50 l/min). Each installation includes generator of high-voltage pulses, electrodischarge chamber, and some of them has control system. Control system ensures the smooth operation of the installation for the time due to the presence of the consumable electrode material (wire). These installations are bases for the experimental test bench arranged with the diagnostic devices and necessary ancillaries both for investigation of the PED and for study of properties of the WDN of various metals and their oxides. During the research were developed several high-voltage pulse generators for electrodischarge treatment of liquids with various specific electrical resistivity ranging from distillated water to weak water solutions of salts (2–55 μS/cm). Electric discharge chambers are usually monoblocks of polycarbonate (Lexan) with openings for water inlet and outlet and a pair of electrodes located coaxially. Axis of the electrodes is perpendicular to the flow of water.
