How Does Ozone Laundry Work?

Ozone Laundry Systems for Commercial On-Premise-Laundry (OPL)

Conventional and OLS Washer Step Comparison

CONVENTIONAL WASHER STEPS:

  1. SUDS - Hot Water
  2. BLEACH -Hot Water
  3. RINSE -Hot Water
  4. EXTRACT
  5. RINSE - Cold Water
  6. FINAL RINSE - Cold Water
  7. EXTRACT

OLS WASHER STEPS

SUDS: Alkali (soap) is added with cold water, causing the textile fibers to swell. The bonds between the soils and fibers are broken, and the soil is oxidized. The pH is raised to a slightly lower level than a conventional wash process. As a result of the fiber swelling, less water is needed to rinse out the residual alkali.

BLEACH: After soil removal, stains are oxidized by the combination of bleaching agents and ozone. As the wash cycle continues, the bleach is eventually neutralized, leaving no residual in the linens. This helps to minimize the linen damage that is often caused by residual chemicals, without a reduction in brightness or stain removal.

SOUR: Sour is still used to adjust linen pH to a proper level. The sour also allows the ozone to continue the cleansing process.

SOFTENER: Fabric softeners are no longer needed because alkali and acid do not create salt crystals. This results in a better extract, shorter drying times and more absorbent linens
