Ozone laundry system has distinct advantages over conventional chemical and hot water laundry. Commercial and industrial laundries use tremendous amount of water, chemicals and energy. They also produce hazardous waste water which needs to be further treated before reuse or disposal.
Hotels, hospitals, railways, defense have very large in-house laundries. The cost of operating these laundries is high due to labor cost, energy cost & requirement of fresh water. Along with this they also face stringent safety, health and environmental norms. Due to considerable savings in energy, water & chemical, many commercial and Industrial laundries have shifted to ozone laundry system.
Advantages of ozone laundry systems:
There are distinct multiple advantages of using ozone in laundry system.
1) Savings in Energy Cost :
Ozone at lower water temperature is more effective in regular lightly soiled linens and other clothes. This property significantly reduces or eliminates the use of steam or hot water. For heavily soiled cloths, hot water may be required to efficiently break down greases and oil. Under these conditions ozone enhances the effect and efficiency.
A typical reduction in hot water or steam generation can be 60-100 % and energy saving can be 40 – 80 %. Ambient water washing also increases the life of the linen and reduces carbon foot print and earns significant point in LEED rating.
2) Saving in chemical consumption :
Ozonated laundry system requires less amount of detergent as ozone has a property of dirt oxidation and breaking of chemical bonds holding dirt particles. Also ozone significantly reduces the bleach demand since it has bleaching property. There is an addition of PH reduction chemical demand unlike advantage in chlorine bleach because ozone works on wide range of PH.A typical saving due to reduction in chemical consumption is 20-60%.
3) Saving in fresh water demand / consumption:
Since ozone laundry uses less chemicals and bleach it can reduce water quantity as well reduce one or two rinse operation. During rinse operation ozone works in four ways. During rinse cycle it not only rinses the detergent but also sanitizes the linen, oxidizes odor and bleaches the fabric.A saving in water quantity of 10-25% the conservation of water also earns lead points in green certification.
4) Reduction in operation and labor :
Since hot water is not required, the operation and maintenance cost and time is saved. Less labor is required because of reduction in rinse operation of heavily soiled as these cloths demand rewashing. Due to high efficiency of ozone laundry rewashing, it can significantly reduce this demand by 70-90%.General reduction of operation and labor can be typically 10-20% .
5) Increased life of linen due to lower :
Life of linen is naturally increased due to three factors. One, due to lesser use of strong chemicals like detergent and bleach. second use of ambient temperatures and third, shortened operation of washing and drying. The significant reduction in broken lint is immediately observed and indicates extended life.A typical extension of linen life in hotel industry is 15-50% and in hospital is 25-65% .
6) Some additional advantages :
Ozone washed lines are more fresh and free from any odor.
Linens are noticeable soft and fluffier.
Reduction in waste water quantity.
Less waste water treatment is required for reuse or disposal. This is mainly due to insignificant by products, ozone keeps treating waste water and any residual ozone reverts back to harmless oxygen.
Absence of hot water reduces the overall temperature of the facility and surroundings.
Fabrics are more sanitized due to high ozone property.
7) Lower return on investment :
Lastly due to saving in energy, labor, chemical, extended linen life gives rapid return on investment.
The typical ROI can be 12 to 18 months.
