PENGHILANGAN KANDUNGAN MIKROORGANISME PADA AIR DENGAN MENGGUNAKAN SISTEM PLASMA RADIOFREKWENSI SECARA KONTINYU

Abstract

Abstract

Radio Frequency (RF) Plasma System is one of Advance Oxidation Process (AOP) and it is used to remove microorganisms in water. RF plasma radiation can generate the active compounds such as H⁺, OH^-, H₂O₂, and O₃. Radio frequency (RF) can be used to remove of microorganisms and organic pollutans due to high chemical activity, low temperature and short time treatment.The applied frequency was set at 3.0 MHz and flowrate at 30 mL/minutes to see the effect of diameter plasma reactor at 1, 2 and 3 inch. The results indicated that in all runs the removal efficiency of Fecal Coliforms waslower than Total Coliforms. Kinetic of death (k_D) of Fecal Coliforms in the range  is 46 % higher than Total Coliforms, while the k_D decreased with increasing of diameter reactor.
