Gas Nature Effect on the Destruction of Various Microorganisms Under Cavitation Action

Abstract

The disinfection of water from Diplococcus, S.lutea, B.cereus, and Ps.fluorescens bacteria types and the yeast Sacch.cerevisiae via the joint action of gas/US has been investigated. The investigated microorganisms were identified in natural water and wastewater in dominant amounts. The relative ranges of effective cell destruction by combined gas/US action have been established. The most efficient microorganism destruction has been obtained using Ar/US compared to Не/US, СО2/US and О2/US and is accounted for by those gas properties able to affect sonochemical activity.
