Add drinking-water and out comes softened and disinfected water of drinking water quality– how?

Most people do not think about that drinking water contain minerals as NaCl (salt), but it does – and this is the secret to inline electrolysis and disinfection. When the water enters our system, it first undergoes a filtration process to remove calcium carbonate and other impurities. A flowmeter measures the water volume, and an adequate number of electrons is led through the water using a set of special designed electrodes adjusted according to flow and salts in the water. This process generates active chlorine in form of hypochlorous acid and hypochlorite – a very powerful oxidant that kills bacteria and other potentially harmful microorganisms similar to the hypochlorous acid production in our body’s immune system. To receive extreme high degree of disinfection bacteria is caught in our biozone reaction filter that secures full effect of the active chlorine. Thus, the water comes out softened, disinfected and of drinking water quality – but still containing a residual of active chlorine ensuring biofilm control in the water system.

Adept Water Technologies is the manufacturer of medical equipment class-I drinking-water disinfection systems, for both stand-alone and build-in applications.

The Ugly Duckling – The perfect environment for biofilm formation

How many times a day do you encounter biofilm without knowing? Probably many! Biofilm surrounds us in our daily life. If we leave out the fact that biofilm formations can occur inside the human body, we are still in contact with biofilm regularly. Where? – you may ask. You can find biofilm on your toothbrush or inside your yellow rubber duck in your bathroom. You might also find biofilm on your teeth or in water pipes. The list is endless. 

The conditions found in a bathroom causes the perfect environment for many microorganisms with higher temperature and increased humidity.  Tap water can comprise microbial communities and in some cases also opportunistic pathogens, such as Pseudomonas aeruginosa, Legionella pneumophila, and Mycobacterium avium. However, the nutrients in tap water will normally not contribute to excessive microbial growth.

On the picture a rubber duck has been split in half and the biofilm formation is visible for the naked eye. The polymeric material in contact with drinking water releases substantial amounts of organic material that microorganisms can use as a source of nutrition. The picture emphasizes the need to be able to control and limit the microbial communities in potable water. At Adept Water Technologies we specialize in systems disinfecting potable water.

The 3 kill-zones in a dental treatment center

For decades dentist and dental manufacturers has struggled to keep bacteria out of their units. It has been a losing battle, using various filters, or dosing of various chemicals. The picture below shows the inside of a water container that is part of a dental unit water line with bacterial growth.

None of it has proven a steady functional effectiveness, nor any sign of hygiene management that works on an everyday basis. Dentist are obliged to test for bacteria counts and to provide clean water with low counts of colonizing forming units (CFU) to the patient, having oral procedure.

The Hygowater© devices from Dürr Dental and the ActiveAqua© from Planmeca has changed all that.

Both systems provide a triple kill-zone for incoming bacteria and virus.

  • The integrated electrolysis chamber kills instantly most of all incoming bacteria and virus by producing a controlled amount of free chlorine in the water.
  • Ultrafiltration holds back bacteria and virus such as legionella and E-Coli and kills them. At the same time the free chlorine, produced by the electrolysis is keeping the ultrafilter clean.
  • The surplus of free chlorine produced, kills and eliminates the pre-existing bacteria and virus in the dental unit. Keeping the water clean from microorganisms such as Legionella, all the way to the patient.

The entire system provides “Peace-of-mind” to the dentist, the assistance and the patients.

Is pathogenic waterborne microorganisms a threat in the western world?

A question we often get at Adept Water Technologies is – why are you doing water disinfection, is it at all a problem in our part of the world?

In 2016 WHO published a report “The situation of water related infectious diseases in the pan-european region” with the definition of a water-related disease as, “any significant adverse effects on human health, such as death, disability, illness or disorders, caused directly or indirectly by the condition, or changes in the quantity or quality, of any waters”.

The report identified 36 microorganisms potential related to water-related infectious diseases. It also identified hundred thousand of cases over a 10-year period from all areas of Europe. In general this report only focuses on larger outbreaks, meaning case stories only involving a small number of individuals is not registered (legionella cases in EU is more than 10.000 / year).

In the end the report concludes:

“Available Water Related Disease data likely represent only a small fraction of the total number of disease cases occurring in the population.”

Even then the majority of countries has a surveillance system the conclusion is – “This indicates a need to prioritize and undertake systematic actions to strengthen and maintain the national surveillance capacities necessary to meet the requirements of the IHR, and to ensure effective WRD surveillance and outbreak response systems as required in article 8 of the Protocol on Water and Health.”

So, the answer to the question is – Yes – Water Related diseases is also a problem in our part of the world. Adept Water Technologies will therefore continue to develop and manufacture water disinfection systems – that is easy and safe to use – and in the end can guarantee us safe water at the dentist, in the shower, drinking water or other water sources where disinfection is necessary.
