Did you know that Ozone means a Chemical-free Laundry?

Ozone application in commercial laundering was first introduced in the United States in the late 1970s-early 1980s. There are several advantages to use an ozone generator system in laundry, not only economic benefits as well as microbiological and environmental advantages.

Ozone laundry systems reduce cycles times, water, energy, sewer costs and chemicals, because of the ozone properties. Ozone is a highly disinfecting and oxidizing agent able to eliminate efficiently organic and inorganic compounds.

Ozone replaces many of the chemicals normally used in a traditional laundry process. Ozone is dissolved into water, replacing chemicals. This is one of the major aspects of textile care that serves to improve the efficiency and to reduce operating costs of a laundry machine. Ozone laundry systems greatly decrease the environmental impact compared to traditional laundry service operations.

It will be important to realize that high-quality standards could be achieves without using hot water and chemicals. Ozone is a highly effective oxidizer that delivers many cleaning factors to the laundry process using only cold water. Also, ozone is a powerful bleaching agent and improves textile life and quality. Shorter cycle times and cooler temperature water means less wear and tear on textiles.

This system is used in commercial laundries but also in hotels, households and hospitals. Ozone washing increases textile life, reduces energy costs, allows faster fill rates, shorter wash cycles, and even shorter drying times. Whiter, softer, sanitized and fresh smelling clothes result in huge savings.

Common Ozone Laundry Applications

  • Commercial laundries – to lower costs of energy and water, and provide clean, fresh and sanitized clothes to the customers;

  • Hotels – to lower costs with chemicals, water and energy;

  • Nursing homes – to reduce cross contamination of illness and infections;

Economic Benefits

  • Chemical savings – Ozone replaces many of the current chemicals used and saves amounts of about 21%;

  • Water savings – Ozone wash systems normally require fewer rinse steps, thus reducing water usage by an estimated 30–45%. In the other hand, these systems recover most of the water (reductions in water use can reach 70–75%);

  • Electrical savings – Less rinsing lowers rinse cycles;

  • Natural Gas savings – Ozone is more efficient with cold water, lowering the energy necessary to heat the water (Energy savings range from 86-90%);

  • Labor savings – With less rinsing, wash loads can be completed faster (labor savings of 39%).

Microbiological Benefits

  • Ozone will reduce all bacteria and virus that may be in any clothes: linens, wiping cloths, towels;

  • Reduction of cross contamination of illness has been documented in nursing homes and hospital facilities using ozone laundering;

  • No hazardous waste as ozone quickly decomposes to oxygen;

  • Does not release halogenated organic compounds (AOX) in wastewater.

Environmental Benefits

  • Less chemicals used in the laundering process means fewer chemicals discharged with the wastewater;

  • Less chemicals discharged in the environment;

  • As ozone oxidizes organic soils on laundry, the oxidized materials become more easily biodegradable by microorganisms in sewage treatment plants and/or receiving waters;

  • Lower COD (Chemical Oxygen Demand) levels in discharged water.
