Central Disinfection System


Dissolved ozone solution for continuous water disinfection in infection control

Major Functions:

  • Continuous Water Distribution Disinfection
  • Biofilm and scale prevention
  • Enhanced sanitation for medical environment
  • High quality water for each point-of-use through out entire facility

Biofilm/bioslime is a complex, dynamically interactive multicellular community protected within a heterogeneous exopolysaccharide matrix. Its formation results in the genesis or perpetuation of infection, enhancement of inflammation, and tissue damage or death. Industrial financial losses result from biofilm/bioslime formation; however, the consequences in the medical realm are equally devastating. General anti-infective strategies are aimed at rapidly killing planktonic forms of microorganisms without specifically targeting the sessile forms that perpetuate their planktonic brethren.

The ultimate prevention of infections is to completely eradicate the reservoir sources of biofilm formation. Ozone’s molecular oxidation capabilities, effective for microdestruction, can be employed in a CIP process of a water distribution system and is the best approach against biofilm buildup and prevention of microbial colonization, the source of biofilm.

While heat disinfection is costly, chemicals can leave residual and UV cannot be reliable, ozone has provided the economically lasting solution to sustain risk-free water supply system for medical operations.


An optimal technology for assured safety of water treatment and infection control

Quality assurance of water supply in medical environments is a critical factor to overall patient care as well as the on-site infection control. Any missteps in cleaning and disinfection procedures or improper functioning of equipment can put patients at great risks.

Mother Nature's Sanitizing Solution

Ozone Creation: Singlet Oxygen (O) - Oxygen (O2) = Ozone (O3) Ozone Dispersion Ozone (O3) - Bacteria, odor, pesticides = Oxygen (O2)

Ozone (O3) is Mother Nature’s gift for safer, more effective sanitation. Ozone is the most powerful naturally occurring agent – the same element that cleanses the Earth’s atmosphere, balancing the bacteria population and neutralizing harmful chemicals.

Ozone exhibits a short 20 minute half-life and it reverts to oxygen rapidly because it is simply oxygen (O2) with an extra oxygen atom. Thus it quickly kills pathogens and does not build up on surfaces the way detergents and chemicals can. In 1991, the US Environmental Production Agency (EPA) confirmed that ozone is the most effective primary disinfection available for drinking water.


Ozone's Bacterial Disinfection Mechanism

Ozone’s bactericidal action prevents superbugs from developing by destroying the drug resistant genes

Ozone oxidizes bacteria cell wall and membrane, allowing water and additional ozone to enter the cell.

The sudden flood of ozone (O3) and hydroxyl (OH- ) dissolved in water (H20) causes cell lysis, and as it bursts, the genetic material and enzymes are released into the ozonated water.

In the ozonated water, the unleashed cell components are attacked by the ozone so that it cannot recover and no resistance is built up.

After contact with the various cell components, ozone (O3) reverts back to its stable oxygen (O2) state. Therefore, there are no residues and no final rinse required.


Biowell Electrolytic Ozone Generation Technology

Biowell uses the world’s leading ozone generation technology, Biowell Electrolytic Ozone Generation (EOG) technology.

Electricity is applied to water and produces high purity, high concentration ozone (O3) and oxygen (O2). It is unlike traditional ozone generators that use air as the source of oxygen.

Biowell’s patented EOG technology generates ozone directly from tap water that is purified within a patented Pure Water System. No other substance besides water is used in the electrolysis, so only pure ozone without any harmful by-products (such as NOx) is produced. In addition, patented dissolving technology uses high-pressure nebulization to achieve superior ozone dissolution efficiency.

  • Meets US OSHA off-gas safety standards
  • Requires only tap water and electricity
  • Environmentally friendly operation
  • Free of toxic by-products

Highly Dissolved Ozonated Water

Ozone Can Be The Solution!

Ozone is the most powerful oxidizing agent that is not a chemical, and formed from oxygen through an on- site generator. Dissolved in water, ozone will eradicate any existing microorganisms and biofilms without residual. As stated by Association of Medical Instrumentation (AAMI) in 2004, ozone is the most effective means for reducing and removing biofilms to enhance qualtity assurance and safety of patient care.


Outperforming To Chemical Disinfection

Chemical disinfection is the most typical method used, commonly employing chemicals such as bleach (chlorine), peracetic acid/hydrogen peroxide mixtures, and formaldehyde. The uncertainties and concerns with this method are incomplete disinfection or incomplete flush where residuals and trace chemicals remain in the system. There have been many documented reports of adverse reactions and casualty due to residual chemicals after sanitation.


Enhancement For Filtration System

Most filtration systems with activated carbon remove biological contaminants along with chlorine, therefore no residual disinfection remains. This undesirable side effect of filtration systems will facilitate the growth of biofilm in the pipeline.


Superior To Ultraviolet Lamp Disinfection

Many problems arise in the operation due to the lack of residual disinfection after water filtration systems. Activated carbon filtration removes chlorine but leaves all water supplies prone to contamination risks. By replacing these disinfection systems with ozonated water, there is continuous disinfection throughout the whole facility.
UV disinfection uses a specific wavelength to disrupt bacteria cells, however, there are certain difficulties associated with this method:



Biowell Solutions CDS - Central Disinfection System

The CDS seamlessly integrates into back-room central water supply of any operation to provide point-of-use (POU) water disinfection and maintain optimal water quality through an entire facility.

The system requires only municipal tap water and utilizes Biowell’s patented EOG technology for safe and efficient ozonated water production.

The CDS can provide ozone sanitized water up to 3,000 litre/hr to multiple outputs, without any other external equipment, including all water taps and faucets.

The system is as simple as follows:


Ozone Delivery
High purity ozone gas generated by the ozone generator is delivered to the dissolving device for dissolution in water and distributed in the supply system. Oxidation starts to take place immediately on microbes, organics, bacteria and viruses.


Contact & Mixing
Along the pipeline the retention time allows a sufficient contact and mixing. The pipeline is maintained free of bacteria and biofilm.


Residual ozone is delivered throughout the water distribution system anytime to allow the system and pipeline are free of bacteria and biofilm.

We Do What Others Can't

Biowell makes the application of ozone in treatment of water supply and the distribution system available and reliable for integration with any existing facility setup.


Low variability with environmental factors

Biowell’s patented EOG technology generates pure, high concentration ozone directly from municipal water purified within our ozone systems. Operation and performance is independent of operating environment factors, such as air quality and humidity, which are common causes of failure in traditional Corona Discharge Systems. (Corona Discharge is the majority type of the traditional ozone generation technology that is known to be highly dependent to the environments for reliable operations).


Nitrogen / NOx and associated algae problem

No other substance besides water is used in the generation process. Therefore, only pure ozone is produced, free of any by-products (such as NOx) and without additional substances in the output (such as nitrogen). Any presence of nitrogen promotes microorganism’s growth, including algae, which are the main reason for system failure and a significant shortcoming in applications of medical water treatment using traditional Corona Discharge.


Easy auto control, optimizing daily self-maintenance & CIP process
