The corona pandemic teaches us that a virus like SARS-CoV-2 knows no borders and spreads swiftly across the entire globe.
As a manufacturer of wastewater treatment systems, since the beginning of the pandemic we have been increasingly being asked about the extent to which our technology can counteract these viruses.
We will not claim that our patented membranes DVZ-BMSU (Biomass Separation Unit) specifically filter viruses from biologically treated wastewater. The cross-flow membranes we use also retain a proportion of viruses, but no reliable values can be defined for this. It is also still disputed how long and whether viruses such as SARS-CoV-2, which triggers Covid-19, survive in wastewater.
However, we do of course take our customers' concerns seriously, so that we have also thought twice about the configuration of our systems with regard to viruses such as SARS-CoV-2:
The membranes used in our plant types DVZ-JZR "BIOMASTER"© and DVZ-SKA "BIOMASTER"© ensure that there are no solids in the output permeate in which viruses can "hide". Because if solids are still present after the clarification process, any pathogens trapped in them will not be reached and not killed by a downstream disinfection system.
Since the special membrane technology of our wastewater treatment plants optimally excludes precisely these remaining solids, we can speak of the greatest possible certainty that even the last pathogens, which may nevertheless have passed the membrane stage individually, are eliminated by a (for example) downstream UV unit.
