Introduction of Fine Bubbles to Aqueous Washing Processes

Abstract

Fine bubble (“FB” hereafter) water, an aqueous solution containing gases such as ozone and oxygen, is able to contain more gas when it is in the supersaturated state. This characteristic lends promise as a revolutionary kind of functional water with applications in the washing field. In particular, ozone FB water, which reported to provide powerful antiseptic effects, has entered real-world use to replace chlorine-based agents for washing vegetables and cleaning toilets. The present report explains the detergency effects of FB water by measuring cleanliness and detergency rates of the selected model soiling, using the removal of ATP (adenosine triphosphate) as an index, as part of efforts to advance the application of FB water to water-based washing. In addition, we will introduce the effects of varying ozone concentrations and effects when combined with surfactants and the soil removal capacity of ozone FB water. In addition, we will introduce the effects of varying ozone concentrations, and effects when combined with surfactants and compared the soil removal capacity of ozone FB water.
