Abstract:
A novel system and method for purification and disinfection of water containing contaminates is provided. The system includes an aeration column, a first intermediate tank, a first mechanical filter, an electric discharge device, a second intermediate tank, a second mechanical filter and a sorption filter. The water is firstly aerated by continuous mixing the water with air and ozone-air mixture. The water obtained after the aeration is treated with coagulant materials in a medium of the ozone-air mixture. Further, the water is filtered from coagulated particles. Thereafter, the water is treated by electric discharges in an air medium. The water is then treated again with coagulant materials. Finally, the water is filtered from remaining contaminates.
Abstract:
A high efficiency plasma processing system for use in the generation of large quantities of gases, particularly hydrogen peroxide or ozone, for chemical commercial and industrial applications is based upon a homogeneous electrical glow discharge. In addition to the homogenous discharge, the high efficiency of ozone or other chemical production is achieved by exciting the discharge with high voltage pulses which have a voltage rate-of-rise in excess of 500 V/ns and incorporating an internal gas circulation system which maintains the temperature of the process gas to a level where the thermal decomposition of ozone, for example, is significantly reduced. A homogeneous and stable atmospheric glow discharge is developed by preionizing the discharge region with ultra-violet radiation, for example, immediately before the application of the main high voltage pulse across the electrodes of the discharge cell.
