When it comes to cleaning, traditional wiping with water or dry dusting is usually what comes to mind first. However, these methods do little more than moving dirt around.
In the setting of the COVID-19 pandemic, efficient methods are needed to decontaminate large open areas and frequently touched points since contaminated surfaces are a potential source for the dissemination of many bacteria, viral and fungal pathogens.
What is Electrostatic Disinfection?
An electrostatic spray that is electrically charged with an electrode is used to dispense a specialised disinfectant solution. As the disinfectant leaves the electrostatic sprayer, it is given a positive or negative charge.
Most electrostatic sprayers generate positively charged particles because most surfaces are negatively charged. The positively charged disinfectant will repel each other and seek out a negatively charged surface to attach itself to. This allows the disinfectant droplets to wrap around and evenly coat all types of surfaces.
Is it Efficient?
Surfaces that are already covered in the charged disinfectant will repel away more disinfectant, making the method very efficient. It also eliminates the danger of overusing disinfectants.
For nooks and crannies that are hard to reach, cleaning staff only have to point and spray. The nature of the misting process allows it to coat even the hardest to reach corners evenly.
The misting process reduces the time taken to cover and disinfect surfaces, hence an efficient method, especially for large areas.
In a study by the US Environment Protection Agency in a hypothetical situation of responding to a bioterror event, revealed that after a 5 minute contact time, electrostatic sprayers performed on par with (or depending on the surface tested, better than) traditional backpack sprayers.
So, like conventional disinfection, electrostatic disinfection kills unwanted pathogens from surfaces, however, it does not create a protective barrier, hence it will not protect those surfaces from being contaminated again.
Regular disinfecting is recommended especially for high footfall areas as well as places like hospitals and schools.
At De Hygenique, electrostatic disinfection is offered as one of the methods to disinfect large spaces, especially for commercial and public areas such as schools, corporate offices and hotels.
We also customise and recommend the frequency and type of disinfection solution, based on the clients’ needs and surface conditions.
