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.

NFO about the COVID-19 virus in drinking-water and active chlorine as disinfectant

Although persistence in drinking-water is possible, there is no evidence from surrogate human coronaviruses that they are present in surface or groundwater sources or transmitted through contaminated drinking water. The COVID-19 virus is an enveloped virus, with a fragile outer membrane. Generally, enveloped viruses are less stable in the environment and are more susceptible to oxidants, such as chlorine.  …… In places where centralized water treatment and safe piped water supplies are not available, a number of household water treatment technologies are effective in removing or destroying viruses, including boiling or using high-performing ultrafiltration or nanomembrane filters, solar irradiation and, in non-turbid waters, UV irradiation and appropriately dosed free chlorine.
