Summary on Grant Application Form |
To allow process industries to recirculate/reuse their process water, it is intended to use and underwater plasma in a specially designed vessel to inactive bacteria and yeast contaminants and break down organic molecules by a combination of UV emission, pressure pulsations and cavitation. A repetitive discharge will be operated underwater to produce a high temperature plasma emitting in the shortwavelength UV. By employing short duration pulses the plasma is confined by the water and high pressure waves are generated. The pressure pulses lead to declumping of yeasts and bacteria cels allowing more penetraction of the UV, and cavitation results in pyrolysis like conditions within the cavities, leading to breakdown of organic bonds. The combination of these effects will results in enhanced pourification. Other possible areas of water treatment where the system could be used efficiently or be used to increase the efficiency of conventional downstream treatment units will also be investigated. The unit is expected to be compact, to require around 200J of energy per litre of liquid treated, will not require regular cleaning and will have low maintenance requirements as a result of the absence of moving parts and fixed light source.
