Abstract
Abstract
Plasma based treatments are found to be effective in water cleansing. For this purpose, we employed a plasma jet that is extracted at the exit of a flexible plastic tube remotely from its main source. This plasma jet is generated using a gas mixture of argon and oxygen for the sake of producing reactive oxygen species in the solution when submerged safely under water to perform a treatment in the suspension volume. The treated samples consist of distillated water that is contaminated with bacterial cells of Pseudomonas aeroginosa, this bacteria can present extreme threat to the human body and may lead to death. Our study reports the effect of both treatment time and the introduced ratio of the gas mixture introduced to ignite the plasma discharge. Results illustrate that full water decontamination can be obtained after about 12 minutes of treatment using 1.5 slpm of argon gas flow in addition to 2.5±0.2% of oxygen.
