Clean and cold water with dissolved Ozone provides excellent cleaning effect in all single-color laundry operations. Ozone is most suitable in laundries at hospitals, hotels, prisons, etc., where white or single-color textile is the most frequent kind of textile. AZCO ozonation systems have been in laundry operations for many years.

  • Ozone in cold water cleans all light and medium soiling. There are great saving on the heating bill and the detergents.
  • The discharge water is so clean that it easily meets the toughest environmental regulations. The BOD reading is well below the limit and ozone does not alter the pH readings.
  • The cleaning water can be re-used as many as ten times (depending on conditions) and the final discharge is still within the regulatory limits.
  • Where the source water is soft, the washing cycle can be shortened up to 50%, This increases the capacity of the washing machines.
  • Some customers may prefer more conservative approach, especially where local regulatory requirements may be quite specific. In these cases a limited water heating (up to about 45oC) and small use of detergents will not harm the process. In warm water ozone degrades faster and this is why we can not exceed 450oC. Even at close to 0oC ozone provides much better cleaning when compared with 100oC hot water and detergents.

  • Examples from our files:

    Ramada Inn - a hotel in New Jersey - reports savings of 40% ($ 4,245.-/year) on water and sewer charges, $ 4,300.-/year on Natural Gas for heating and 54% ($ 4,380.-/year) on detergents. The investment return depends greatly on the number of washing machines, because one ozone system can serve one or many machines. It was reported that even with just one laundry machine the investment return was very good.
    2. Marriott hotels - at two locations: "Water use was reduced by 80%, chemicals reduced by more than 90%, laundering time reduced by 40%, and heating energy savings are 100%. The linen shows no staining and no bacterial reading, "better than ever before".
    3. Beachcomber hotel in Hawaii reports $ 150,000.- savings per year with $ 99,000.- installed cost of ozone system.
