In the present work, a pulsed pin-to-plate corona reactor has been used for phenol removal from water. The main advantage of the present reactor is the presence of electrospraying of water drops at the tip of the discharge pin simultaneously with cor

In this paper, emission spectra of both positive column (PC) and negative glow (NG) regions of the dc glow discharge have been measured at different pressures and currents. The intensity of the lines in the NG is in the order of five times of that co

A silent discharge ozonizer has been constructed with a design that enables the study of ozone concentration behaviour as a function of different parameters when oxygen used as a working gas. The behaviour of ozone concentration as a function of disc
