Electrostatic Disinfection (ED) is a technique that involves the use of a powerful E-field to permanently sterilize and remove all foreign particles, ions and metals from surfaces and materials. Electrostatic Disinfection utilises a combination of ultra-violet light, high frequency electricity and a high voltage pulsed charge. This E-field generates a large amount of positive ions, which bind to all foreign particles on contact.
The most common applications of electrostatic technology include the cleaning and maintenance of sanitary environments in the food service industry and the manufacturing and storage industries. These applications involve the use of machines such as electrostatic brushes, air compressors, sprayers, foam applicators and other machines. Some sprayers are capable of providing ED without the use of machines or humans. It is also possible to use non-traditional approaches such as live containment, physical and chemical barriers and natural ventilation. Many organisations implement various methods of electrostatic security through the application of various techniques and products including:
An electrostatic spray disinfectant sprayer consists of two different nozzles that are connected to a central reservoir. The nozzles open up into two halves, each holding a container holding a small volume of disinfectant. The nozzles open at a 45 degree angle, releasing the chemicals into the container carrying the bacteria or virus. The central reservoir is then closed and the device is used as normal.
The first type of electrostatic sprayer disinfection nozzle is often referred to as the wraparound coverage or helical type. This type of nozzle creates a fine spray that works well on hard surfaces such as stainless steel, granite and concrete. The Helical mode of operation, which is more commonly referred to as a needle model, works best on softer surfaces, and the most suitable application will depend on the surface to be treated. Some nozzles also feature a wide-spaced pattern and an optional dual needle option for use on soft-textured surfaces and other uncommon applications.
Electrostatic Disinfection Dispensers or commonly known as electrostatic cleaners are becoming increasingly popular with businesses as they are proving easier to use, require less maintenance and can reach into places where other disinfectant sprayers may not. These devices work by attracting airborne particles and attracting them to metallic surfaces which are either coated or bare. The electrostatic attraction and repulsion properties of these particles attract both airborne viruses and bacteria, which could be carrying them. They also act as a neutralizer against airborne particulates such as dust and pollen, and will therefore not affect the health of humans when in contact with contaminated surfaces.
There are two types of electrostatic sprayer available to consumers; electrically operated and mechanically operated. The most common type of electrostatic sprayer is the electrically operated version which works by injecting a high voltage charge into an area where it is likely that particles will be airborne. This charge is conducted through an electric conductor into the suspected areas and is then attracted to airborne particles such as dust and airborne allergens. This device is able to reach into hard to reach areas where mechanical disinfection methods may not be able to reach. These types of electrostatic sprayers are therefore extremely useful for treating a wide variety of indoor and outdoor contamination, as well as on machinery such as forklifts and air conditioning units.
The other type of electrostatic disinfection sprayer is a more recently introduced device called the wraparound coverage. This type of device allows for a higher level of aerosol exposure than the previous models. As it is larger than the prior versions, it is able to cover wider areas and therefore has a greater potential for spreading contaminants and germs to other areas of your facility or workplace. Both these types of devices use different methods for delivering their current charge to the surface to be treated. They also have different spray rates and different maximum contaminant levels to best protect your staff and other employees who spend a large amount of time working in and around these contaminated areas.
Both devices use electrostatic technology to kill microorganisms, bacteria, and viruses, however there are differences between the two as to how they achieve this task. Electrostatic sprayers are recommended as the primary means of disinfection for preventing the transmission of pathogenic bacteria and viruses, whereas the use of a Clorox system is recommended for use when direct contact with surfaces is not desired. The use of Clorox is only recommended when surfaces being treated are expected to come into contact with disinfectants. Using a combination of either a Clorox system or an electrostatic sprayer is generally a good idea as both methods offer excellent protection from harmful bacteria and germ spores and should be used as a preventative measure as opposed to an acute response to contamination.
