Omicron Covid-19 variant found in wastewater of California, Oregon and Texas cities (FOX news 10.12.2021).
“Traces of the Omicron Covid-19 variant have been found in the wastewater of American cities.

In many occasions, surface water, which contains the effluent of sewages, is mixed with fresh water, filtered and prepared for drinking water again, the eternal cycle.
Some undesired components are not or only partly removed during the treatment and supply of potable water.
They are sometimes hardly or not detectable, and always within the set limits.
The contamination, however increases.
Comfort & More integrates 99,9% effective NanoCeram filters in the Aqua Biolight Clean Water and Clean Air applications thereby preventing unforeseen contamination.
The NanoCeram filters of https://www.fountain-filters.co.uk remove germs at a nanofiltration level, without creating a large pressure drop, usually expected with filters with a very small pore size. These filters have a 99,9% efficiency at 0,2 microns.
Max. flow rate of a Argonide P4,5-10 is 5,7m3/hr (25gpm).
The terminal pressure drop (a pressure drop across a unit at the maximum allowable pressure drop) is 2.4 bar.
Nanofiltration has a very high effectiveness in removing protozoa (for example, Cryptosporidium, Giardia),
Nanofiltration has a very high effectiveness in removing bacteria (for example, Campylobacter, Salmonella, Shigella, E. coli),
Nanofiltration has a very high effectiveness in removing viruses (for example, Enteric, Hepatitis A, Norovirus, Rotavirus).
