Water contamination


At the end of April 2020, during the height of the COVID-19 pandemic, a very serious doubt about the contamination of water in the city of Paris was relayed by the media, followed by a recommendation not to consume this water. Some traces of COVID-19 were found in the non-filtered water of the city.

An article from "Sciences and Future" explained that genome fragments of COVID-19 can pass in the stool of those infected, travel in sewers, withstand pollution treatments and end up in the rivers. This study was done by "Eau de Paris", the public company that supplies the French capitals water.

Hospital Emissions


A large part of the patients affected by a viral infection is concentrated in hospitals, which produce waste of various kinds. If solid waste is supposed to be incinerated, the disposal of liquid effluents is a real concern. According to Palintest, using UV decontamination is a direct way of preventing the virus from spreading.


How can BSL technology guarantee the total absence of virus in rivers by deactivating micro-organisms?


BioSafeLight has developed a photo-decontamination process for turbid (opaque) liquids. This process combines UV-C light with turbulent flow that ensures every single part of liquid receives the adequate dose of UV-C. The microbiological inactivation efficiency of our technology has been verified on a broad range of liquids, including turbid and opaque. The UV light wavelength used in the process is specially absorbed by the DNA of micro-organisms, breaking certain bonds and causing DNA adducts. This DNA alteration prevents germs from replicating, causing their deactivation.

Are we sure the viruses are eliminated?


The process itself can show that it has a similar effect on any type of micro-organism. The light of the appropriate wavelength is absorbed the same way by the DNA of a germ, whether it is a virus or a simple bacterium.

Some of our BioSafeLight customers have successfully used this technology to ensure that there is no risk of a viral presence in their animal feed.

BSL technology has proven itself in the food industry and may also be a solution for water and hospital emissions.
