Water filter reverse osmosis

Here you will find water filters, also called reverse osmosis systems. I also have reverse osmosis accessories in this section. Replacement filters and membranes are included, as are shower filters, shower replacement filters and reverse osmosis taps. You can measure the acid value with a pH meter or determine the conductivity of the water with a TDS. You can also find these water testers here. The measurement is especially important for aquaria.
Viruses, drinking water and reverse osmosis
Viruses could in principle also be transmitted via drinking water. For drinking water treatment, however, viruses are important, which enter the environment via wastewater and may retain their infectivity for a certain time due to their stability. Essentially, this includes the group of “uncovered viruses” that have a high specialization in your host and a low dose of infection and are not completely removed in the course of wastewater treatment.
Examples include: adenoviruses, rotaviruses, noroviruses, hepatitis A and also polioviruses.
The spread via drinking water, however, is rather insignificant.
Our drinking water producers have the task of preventing infections by viruses or other pathogens via drinking water at all times. It must therefore be flawless in terms of disease and hygiene. Therefore, the preparation is geared to the hazard potentials. The so-called “raw water” is treated in such a way that any pathogens contained are removed or inactivated in multi-stage processes. Methods such as filtering techniques, ozone and other disinfection are used.
Viruses mostly adhere to sand, clay, turbidity and are therefore easy to filter.
Viruses are separated particularly effectively by slow sand filtration during the artificial recharge of groundwater.
For this reason, there has been no “virus epidemic” in Germany for many years.

What is specific about coronaviruses?
A “path of infection” via drinking water has not yet been documented for corona viruses.
Scientific studies have shown that coronaviruses have low stability in water/wastewater. Therefore, they cannot be effective in it for long. Drinking water treatment is also no more ineffective for coronaviruses than for others. After a study of other coronaviruses from China a few years ago, it was shown that chlorine dioxide inactivates (oxidized) them.

Reverse osmosis and viruses
The filtration in reverse osmosis systems is extremely effective. Basically, after the last stage, the membrane, only water molecules remain. The pre- and post-filters clean the water precisely because viruses, as described above, often adhere to larger particles and are thus separated early in the course of cleaning and filtering. This is also confirmed by the supplier of my reverse osmosis systems.
The absorption of water also takes place via an area, which is “monitored” by the immune system. So even if a “virus” were to get in there, I do not think that an “infection” would be possible. In any case, in my view, the circumstances, as well as the respective state of mind, are decisive for the onset of a “disease” rather than what is supposed to “come from outside”.

Disinfection with chlorine dioxide
To prevent contamination, I use the CDH3000 chlorine dioxide solution when changing filters. After removing the filters from the filter housings and cleaning them with clear water, I add a millilitre of CDH3000 with 500 ml of water to each housing before closing the housing. After closing all the filters, I open the inflow valve for the water and let the system fill with it. When I notice that water is running out of the previously opened reverse osmosis tap, I stop the water inflow and then wait 2-3 hours. In this way, the chlorine dioxide acts in the entire system including the of the tank (if present) and disinfects possible residues. Then I turn on the inflow and open the reverse osmosis faucet. Now the water enriched with chlorine dioxide can flow out. After 3 tank fillings of the rinse (approx. 9 liters), I use the water again for drinking.
