Professional stainless steel water sterilizers with UVC light, destroy all germs, such as legionella

Sterilization of contaminated water using UVC light is a promising and effective method. UVC radiation (with wavelengths between 200-280 nanometers) can kill bacteria, viruses and other microorganisms by damaging their DNA, making them unable to multiply. This technique is used in various applications, such as drinking water treatment plants, aquariums and laboratories. In order to make a specific recommendation for sterilizing different types of contaminated water with UVC light, it is important to take into account a number of factors. Here are some points to consider:

1. Type of contamination

Microbiological: This includes bacteria, viruses, fungi, and algae. UVC light is particularly effective against microbial contaminants.

Chemical: UVC light has no effect on chemical contaminants such as heavy metals, pesticides, or solvents.

Physical: If the water contains a lot of particles, these can reduce the effectiveness of UVC light, because the particles can block the light.

Recommendation: For microbiological contamination, UVC can be a good solution, but for chemical and physical contaminants, the water may need to be pre-filtered or chemically treated first.

2. Water transparency

The clarity or turbidity of the water affects how deeply UVC light can penetrate the water. If the water is cloudy, the UVC light will not reach all the microorganisms, making the sterilization less effective.

Recommendation: If the water is cloudy, a pre-treatment such as filtration is needed to improve the clarity.

3. Contact time

The time that the water is in contact with UVC light is a crucial factor. The longer the water is exposed to UVC light, the more effective the sterilization. This can be achieved by adjusting the flow rate of the water through the UVC unit.

Recommendation: For water with heavy microbial contamination, the contact time with UVC light should be longer, which can be adjusted by reducing the flow or increasing the intensity of the UVC lamp.

4. Wavelength and intensity of the UVC light

The wavelength and intensity of the UVC light determine how effective the sterilization is. For water sterilization, a wavelength of approximately 254 nm has been shown to be most effective.

Recommendation: Use a UVC lamp specifically tuned to 254 nm and ensure a sufficiently high intensity, depending on the amount and type of water being treated.

5. Capacity of the system

The capacity of the UVC system must be adjusted to the amount of water to be treated. Higher capacities may require multiple UVC lamps or larger units.

Recommendation: Provide a system with sufficient capacity for the intended flow rate and water contamination level.

For different types of water, such as wastewater, river water, drinking water or industrial water, the UVC system must be tailored to the specific requirements

Wastewater: Often requires pre-treatment, such as filtration and sedimentation.

River water: May be quite clear, but often contains micro-organisms and can be treated with direct UVC light.

Drinking water: Relatively clear and ideal for UVC treatment, provided it is free of chemicals.

Industrial water: Depends on the nature of the contaminants (chemical, biological, physical) and may require additional treatment.

Conclusion

UVC light is a powerful technology for sterilizing microbiologically contaminated water, but its effectiveness depends on the nature of the contaminants, the transparency of the water and the correct sizing of the UVC system. For optimal results, it is often necessary to pre-treat the water and choose the right parameters for UVC exposure.

We are all at risk of contracting and spreading viruses and bacteria, especially in public spaces such as offices, shops, schools, public transport, but also at home. UWV-C radiation has been used intensively for more than 40 years and is an effective disinfectant for air, surfaces, objects and water. BBM Ledproducts specializes in UV-C technology. In laboratory tests, our UV-C light sources destroyed 99% of all germs on a surface and in the air with an exposure time of a few seconds.
