The Electrostatic Spray Disinfectant System use is an electrostatic spray disinfectant system with a sprayer nozzle which applies an electrostatic charge to the cleaning solution as it’s applied so it actually bonds and surrounds the area it’s touching. This prevents the flow of water which will tend to carry the solution across the surface of the object and therefore keeping it from coming into contact with any embedded contaminates like dirt or grease. Electrostatic spraying was first developed by American Company Holceton Industries in 1937 for use on railway platforms and then transferred to common application areas. The advantage of using an electrostatic system over other similar systems is that it’s far quicker and easier to use. This also means that there’s less need for manual labor when using the system.
The uses for this kind of system are so wide that many industries have adapted it for use. Some examples are hospitals, cruise ships, construction sites, and manufacturing plants. There are even some backpack electrostatic spray disinfectant system designs that you can take with you on camping trips. I particularly like them for camping in remote locations where there’s no running water and no electricity. In my mind the design must be lightweight enough to allow for easy mobility but durable enough to resist the weather.
There are three types of electrostatic backpack sprayers. The first, and most popular type is known as the mono-line system. These are the cheapest because they don’t include a positive or negative charge unit, but instead use a single small unit that creates a positive charge on contact with the material being cleaned. This means that if something has a negative charge on its surface then it will attract a positive charge from the backpack. These are particularly useful for material like paperboard and cardboard. The only downside is that these tend not to work well on wet surfaces.
Positively charged materials, such as lead or mercury, will repel and not absorb the electrostatic spray. These are often attached to a hose at the end of the wand or contained within an enclosed chamber. These are the most effective forms of electrostatic disinfection and can be very effective in removing organic material from water or damp areas. There are negative charge electrostatic sprayers available, but they are not as widely used as those that include a positive charge.
The most expensive option is a battery powered, self contained unit. They can range from fairly cheap to quite expensive, depending on the brand and features. The key advantages are that they can be more effective than manual cleaning methods, use anywhere from two to eight hours on a regular basis, and don’t require electricity. The disadvantages are that they can be bulky, can require frequent recharging and can be difficult to clean or replace if fogging occurs.
Electrostatic negative charge electrostatic spray disinfectant systems featuring a positive charge on the opposite side of the wand use a high frequency radio frequency to generate a low grade shockwave. When the wand comes into contact with a surface or material, it causes a small amount of heat which breaks down the charge on the material to allow it to escape. This is sometimes combined with steam to further accelerate the process. These units do not require electricity and therefore are cheaper to run than other forms of disinfection.
Manual cleaning methods utilise a long-handled brush or vacuum with a wand attachment to scrub surfaces. These methods are less effective and can be labour intensive. Using a long handled broom with a positive charge is one of the simplest ways to employ electrostatic disinfection. A small positive charge is put onto the wand’s end and the wand is pushed into the material to be treated, and a low or positive electrostatic charge is then generated. The wand is released when the material has been broken down, and cleaning is complete.
The best and most cost effective method of electrostatic spraying is a hospital grade disinfectant sprayer that features a hose attachment. Most modern units feature two removable nozzles that are situated at the base of the unit, allowing them to be attached to the appropriate drain pipe, giving the user full control over the direction and duration of the spray. One nozzle should be placed onto one wall and left for a short while after applying the disinfectant, and then another nozzle should be moved and directed on the opposite wall. In addition to reducing or eliminating the need to manually wash surfaces, this feature can reduce the risk of electrical shorts by preventing the electric motor from being accidentally turned on and off. If any surface remains wet after the treatment, it should be dried as quickly as possible with a feather duster or similar soft cloth to prevent bacterial growth.
