Electrostatic sprayers sanitize spaces
From foggers, traditional backpack sprayers, and electrostatic sprayers, many sanitizing delivery methods are now available on a global scale. While it is clear that sanitizing has become necessary for personal and public safety, for businesses, institutions, and consumers seeking to adopt a cost-effective, long-term approach to sanitizing, the question to ask is, “Which sanitizing delivery method is the most ideal?” The answer to this question resides in both the delivery method and the solution used for sanitizing spaces.
The purpose of fogging is to supersaturate the atmosphere with a chemical fog. A report on fogging further explains the purpose is to, “…create and disperse a disinfectant aerosol to reduce the numbers of airborne micro-organisms and also to apply disinfectant to surfaces that may be difficult to reach.”
Consumers may identify chemical fogging with canisters of pesticide to “bomb” a room. Chemical fogging is also a method used in sanitizing commercial spaces including food production facilities and cleanrooms. Chemical fogging is achieved through built-in systems or a mobile fogging unit based on the size of the room.
The minimum “wet time” for proper sanitization ranges from 1-hour to 1.5 hours. With fogging, humidity and ambient temperatures are factors. For non-commercial businesses and consumers, adopting fogger-based sanitizing processes used by commercial facilities is not practical or affordable.
Manual sprayers involve a canister for containing fluid while a pump action handle uses air to deliver the fluid through a spray nozzle. Manual sprayers go by many names including traditional sprayer, hand pump sprayer, tank sprayers, and backpack sprayers.
Tank sprayers are designed with a pump handle. Fluid from the tank is pressurized by pumping air with a handle located on the tank. The pressurized fluid is then dispersed through a gun-shaped handle or a wand that can deliver a targeted mist to a concentrated stream of fluid. Tanks can range in size from quarts to gallons and are made from a variety of materials including plastic and steel.
Backpack sprayers are tank sprayers that hold slightly more fluid – up to 4 gallons – and are worn over-the-shoulder. Some backpack sprayer designs incorporate a lever pump to maintain pressure and eliminate the need to remove the backpack unit.
With traditional manual pump-action sprayers, speed of application, inconsistent material coverage including dripping, and the distance of material coverage are factors. Traditional sprayers are effective for short distances of about ten feet which falls short of typical roofline and ceiling heights in buildings.
STATIC ELECTRICTY – A SANITIZING INNOVATION
From the kitchen with plastic cling wrap to the laundry room with anti-static fabric treatments, static electricity is all around us. Static electricity is defined as, “… an imbalance of electric charges within or on the surface of a material. The charge remains until it is able to move away by means of an electric current or electrical discharge.” There are a variety of ways to create an electrostatic field including:
- Direct charging an electrode immersed in a reservoir
- Atomized fluid contacting an electrostatic field
- Creating fluid friction by forcing materials through a spray nozzle
Use of electrostatic science for evenly distributing paint began in the 1940s. Electrostatic paint sprayers are designed to leverage electricity polarity to repel molecules thus creating consistent material coverage. Using less material resulted in significant cost-savings for the automotive paint industry and electrostatic painting became a standard delivery method.
Electrostatic sprayers have made an emergence in the sanitizing industry. An EPA study compared the performance of an electrostatic sprayer with a traditional electric backpack sprayer by evaluating the efficacy of each sprayer in removing or inactivating microbe spores (specifically of Bacillus atrophaeus var. globigii (Bg), a surrogate for Bacillus anthracis), from different types of personal protection equipment (PPE) materials. The findings from this U.S. EPA study (USEPA 2015b) found electrostatic technology to be superior for:
- reducing waste
- delivering a more uniform distribution of liquids over uneven surfaces
SELECTING THE IDEAL SOLUTION FOR ELECTROSTATIC SANITIZING
It is important to go beyond scratching the surface of commonly used sanitizing materials to expose the most cost-effective, time-saving approach to sanitizing with electrostatic sprayers. Many references to bleach are available for sanitizing. However, the risks of using bleach to sanitize spaces appear to outweigh the benefits when compared to quaternary ammonium compounds.
BLEACH: Containing sodium and chlorine hydroxide, bleach is a toxic and dangerous chemical that can fill any space with harsh residues and fumes. Bleach odor is known for causing headaches, nausea, fatigue and burning of the eyes, nose, and throat.
Whether a liquid bleach-based solution or a bleach tablet dissolved in water for use in electrostatic sprayers, bleach requires 15+ constant minutes of sanitizing “wet” time. This results in saturating public and private spaces with harsh chemicals and a residual smell that can repel patrons from businesses. Bleach is also well known for discoloring and damaging textiles.
The NIH explains, “…the disinfectant potential of a bleach solution is not constant; rather, it decreases with time because of the relative instability of the active chlorine component. Bleach solutions lose potency at an accelerated rate when exposed to sunlight, oxygen, and heat.” Further affecting the potential for bleach with sanitizing, the CDC recommends rinsing bleach with water from properly sanitized surfaces then air drying.
The pH of water can affect bleach’s ability to sanitize. A University report cites, “The effectiveness of chlorine is controlled by pH, temperature, contact time, and dose. Neutral pH (6.5 to 7.5) produces the maximum amount of hypochlorous acid. If the pH of the water is too low (pH < 6.0), chlorine will escape as a gas, decreasing effectiveness and increasing equipment corrosion.”
The reality is that bleach requires additional steps in the sanitizing process, adequate ventilation in order to create inviting sanitized spaces, and can severely damage textiles, carpet, and equipment including furniture.
QUATERNARY AMMONIUM CHLORIDE COMPOUNDS: A breath of fresh air, GlanHealth™ offers its revolutionary fresh scented sanitizing solution that includes benzalkonium chloride, an FDA approved sanitizing active ingredient and quaternary ammonium compound, and EPA listed ingredients for use with the Company’s electrostatic sprayers and sprayer service.
With a 360-degree electrostatic application range on any surface including walls and ceilings, GlanHealth’s non-hazardous spray formula is non-flammable, non-toxic, and does not require rinsing.
After approximately 10-minutes, on the dry surface is a long-lasting nano thin protective film shield that serves as a long-term barrier to harmful germs, bacteria, allergens, microbes, and odors. GlanHealth™ provides sanitizing persistence for up to 28-days on all surfaces and is safe to use on all types of fabrics.
