Abstract

The efficacies of gaseous ozone and sodium hypochlorite as an oxidizing agent for cleaning were compared in a laboratory model system using stainless steel particles fouled with proteins. Exposure of the protein-fouled stainless steel particles to 0.5% (v/v) gaseous ozone for 30 min enhanced the removal of the various proteins during subsequent alkali cleaning with NaOH solution to the same degree as the NaOH solution containing sodium hypochlorite at 0.2 to 0.4 g/l. The effect of ozone pretreatment on the removal of the proteins depended on the concentration of gaseous ozone. Pretreatment with a highly concentrated gaseous ozone of 20% for 30 min resulted in the almost complete removal of the proteins from stainless steel particles.
