YOUR HALLMARK FOR EXCELLENCE IN HYGIENE & ODOUR DESTRUCTION

OZONE is the Most Powerful Natural Oxidising Agent that Can be Used to Destroy Allergens, Pathogens and Other Harmful Bio-Contaminants. It is Known to be >3000 times More Effective Than Chlorine as a Disinfectant. OZONE Cannot be Contained or Transported, It has to be Generated at the Point of Use.
Thus, We Developed a Methodology, aka the O'Klean Method, by Generating OZONE Onsite and Controlling the Duration (Hrs), Concentration (ppm) and Distribution Rate (CMH) of OZONE GAS, to Specifically Target Large Scale Destruction of Bio-Contamination in a Controlled Space Volume, Where Conventional Disinfectant Methods Are Ineffective, Inapproriate or Too Risky for Manual Cleaning
This Type of Shock Treatment, Must be Carried Out Without the Presence of Humans, is Tested and Proven to Achieve > 99.9999% Destruction of Bio-Contaminants (more than 8.00 LOG Reduction Value) for Both Airborne and On Contact Surfaces. Swap Tests can be Taken to Verify the Killing Results.
Immediate Human Occupancy in the Treated Room After Treatment is Possible Due to the Auto Removal of Excess OZONE GAS That was Generated in The Process of Treatment
Our Sense of Smell is an Excellent Indicatior of Odour Pollution. Thus, Upon Completion of the Treatment By Our Trained Specialists, One Will Instantly Detect the Marked Improvement in Air Quality and this Effect Is Sustainable Because the Root Cause of Odour Would Have Been Destroyed, Not Masked
Harnessing this Killing Power of OZONE Comes the Responsibility of Ensuring Safety Because Not Only Can OZONE Kill the Dangerous Strains of Viruses and Bacteria, It is Also Deadly to Us If We Inhale OZONE at these Concentrations. Thus, Safety Precautions Taken to Prevent Human Exposure to OZONE during The Shock Treatment are Extremely Vital
OZONE Self-Disintegrate into Harmless Oxygen Molecules After a Half Life Period of 20-30 Minutes
Treament Process is Chemical-Free and Environmental Friendly
O'Klean Method: Tests on Bactericidal Killing
Agar spread plates were prepared using varying concentrations of 4 strains of microorganisms, namely
1. Escherichia coli - represents contamination by gram negative microorganisms
2. Staphylococcus aureus - represents contaminations by gram positive microorganisms
3. Pseudomonas aeruginosa - represents contamination by biofilm forming organisms and
4. Salmonella entericarepresents - infectious contaminants in food industry
The test methodology is adapted from the ASTM E 2315 – 03 standard of anti-microbial activity using a time-kill procedure.
These plates used in the study were placed on top of a 1m tall shelf for the bacterial cell density and used to represent various degrees of surface test in a sealed enclosure (simulating a bedroom size), measuring 2000mm(L) by 1800mm(B) by 1800mm(H). Average ambient conditions measured were 25.4oC and 64% RH.
The ozone generator was operated over a range of timings (5mins, 10mins, 30mins, 45mins and 3 hours) producing a bactericidal killing efficiency of 99.9999% for the 4 strains tested.
A final test where the ozone generator was operated for 3hrs in an actual office to represent an actual working environment produced a comparable bactericidal killing efficiency of 99.9999% for the 4 strains tested.
Below shows a summary of the antibacterial efficiency of the ozone generator on the four strains tested. The log reduction value (LRV) is calculated from the number of viable colonies grown in the treated and control (untreated) samples

The effect of 5mins, 10mins, 30mins and 45mins (from left to right column) ozone exposure on the four representative strains of bacteria. The spread plates below display the dilutions at which less than 5 colonies were observed to grow after treatment when compared to an untreated control.

Placements of the Test Plates in the Test Enclosure

Ozone is toxic and can be a health hazard! Yes, that is why it is such an effective weapon against germs and bacteria. But we are not exposing human beings to Ozone during a shock treatment
The WHO has an average Air Quality Guideline of 0.05 - 0.06ppm measured over an eight hour period
The Occupational Safety and Health Administration (OSHA) requires that workers not be exposed to an average concentration of more than 0.10 ppm for 8 hours
US Environmental Protection Agency (USEPA)’s National Ambient Air Quality Standard for ozone is a maximum 8 hour average outdoor concentration of 0.08 ppm
Our trained personnel carrying out the shock treatment using the Activo machine and together with its in-built auto backwash cycle will comply with all above safety exposure standards by certifying (with a calibrated O3 analyzer) that the residual O3 in the treated room will be <0.050 ppm (Air Quality Recommendation by NEA, Singapore) before the room will be made available for human occupancy
