Ozone has been successfully applied incommercial laundry for more then 50 years.

Ozone In Commercial Laundry

Integration of ozone in laundry systems are growing due to:

High Quality washing.Reduction in chemical use.No requirement of Steam.Operational ease.Performance & efficiency.Cost benefit.Environment friendly.

Advantages of OzoneIn

Commercial Laundry

Page 4: Ozone in laundry   cost & energy saving

Odour removal

Ozone is a strong oxidizer.

It eliminates all bacteria & organics causing odour.

Eliminates use of bleach, hence no chlorine odour.

stain removal

Ozone is a strong but natural bleaching agent, hence good for whites & coloured clothes.

Breaks bonds that holds soil & stains to the linen.

Breaks down organic stains like oil & blood stains.

Ozone protects cloths

System uses cold water, avoiding fabric shrinkage, aging & deteriorations caused by using hot water/steam.

Reduced quantity of detergent used.

Eliminated the use of bleach, which makes clothes hard & brittle.

Ozone disinfection

Ozone is a strong disinfectant – about 3 times stronger than chlorine.

It kills all viruses & bacteria.

Prevents cross contamination.

Softer linen

Ozone penetrates inside linens making it fluffier.

Ozone prevents building up of residue in the weaver of the cloth leaving fibres naturally soft & resilient.

Cost of heating water cont. …..

Boiler efficiency is assumed 80%For 39,300 kcal, boiler produces 49,125 kcalHeat transfer losses @ 15% (from steam to washer)Total heat required from boiler is 57,800 kcal. 1 litre of boiler oil can produce 9,000 kcal Total 6.5 litres of boiler oil is used per wash cycleWith 12 wash cycles per day & 300 days per yearTotal oil consumed per washer is 23,400 litresConsidering rate of INR 24/- per litre for boiler oilYearly expense is INR 5,61,000/- (heating cost)

Chemical costs

Bleach (Sodium hypo chloride).

0.75 litre per wash cycle.

Cost of bleach INR 12/- per litre.

Yearly cost INR 32,400/- (Chemical cost)

Ozone costs

Running cost – power consumption – 0.6 kw per hr.Operating Hours – 20 hrs.Considering INR 10/- per kwhr.

0.6 x 20 x 10/- x 365 = 43,800/-

Yearly cost is INR 62,400/- (including Tax & maintenance cost)

Page 15: Ozone in laundry   cost & energy saving

Net saving using Ozone

Operational Cost saving : Heating cost + Chemical cost – Ozone

operational cost⇛5,61,600/- + 32,400/- ̶ 62,400/- =

Other savings & benefits :

Increased life of clothsSaving in water & detergentsCleaner effluent – no chlorine or its harmful by-productsSafer on environment – No burning of boiler oil

INR 5,31,000/-

Commercial Viability / Pay back

Capital Cost : Per system ranges from INR 2.0 lac to 4.0 lac (estimated ozonator life is 10 years)

Pay back period :Cost of net consumables in conventional laundry is INR 5.31 lac.

Capex pay back is 6 months to 8 months
