Ozone and Laundry
Ozone in Laundry Applications: Summary of Benefits
Economic Benefits
- Chemical Savings - Ozone replaces many of the current chemicals used (Chemical savings amount to about 21%).
- Water Savings - Less rinsing of laundry during the cycle saves water.
- Electrical Savings - Less rinsing lowers rinse cycles reducing electrical costs.
- Natural Gas Savings - Cold water can be used when laundering with ozone, lowering the energy necessary to heat the water (Energy savings range from 86-90%).
- Labor Savings - Lower chemical usage lowers the necessary rinse cycles, this in turn lowers necessary labor (labor savings of 39%).
Microbiological Benefits
- Ozone will reduce all bacteria and viruses that may be on any linens, wiping cloths, or clothing.
- MRSA and Clostridium difficile are rapidly eradicated by ozone laundering within 3-6 minutes.
- Reduction of cross contamination of illness has been documented in nursing home and hospital facilities using ozone laundering.
Environmental Benefits
- Less rinse water used reduces the overall discharged water.
- Less chemicals used in the laundering process means fewer chemicals discharged with the wastewater.
- Lower COD levels are found in discharge water when using ozone.
Common Applications of Ozone
- Hotels use ozone to lower costs and save money.
- Nursing homes use ozone to reduce cross contamination of illness and infections.
- Hospitals use ozone to reduce cross contamination of deadly diseases, improve patient health, and lower costs.
- Coin operated laundry facilities use ozone to lower costs and provide a value added benefit to their customers.
- Direct Injection - Ozone can be dissolved directly into the wash water as it enters the laundry machine
- Diffusion - Ozone can be diffused into the bottom of the laundry machine during the entire laundry cycle
- Recirculation Injection -- Ozone is injected into the rinse water outside of the washer, this water is constantly recirculated through the washer throughout the cycles
- No major modifications of the current laundry machines are necessary to incorporate ozone
