In the course of the pandemic, spraying a mist was one of many frequent options opted by native governments, particularly in Southeast Asia. “What” is being sprayed can range. Among the many checklist of chemical substances often sprayed are Bleach, Hydrogen peroxide, Alcohol, Peracetic Acid, or Chlorine Dioxide, for instance. Whereas they will obtain the aim of eliminating the contaminants, they will additionally trigger some stage of toxicity and environmental affect. Even the procurement and storage of those merchandise may be problematic.
PALSOO (all caps) is a Korean firm proposing a intelligent, non-toxic, and sustainable method to obtain the identical consequence utilizing solely water. The corporate makes use of Plasma Sterilization, which solely makes use of vitality and water to generate sterilizing plasma-activated water. No chemical merchandise are concerned.
The Plasma reacts with water coming from the reservoir, creating a mixture of Oxygen and Nitrogen ions, neutrals, and radicals (OH-, O3, H2O2, NO2-, NO3—and ONOOH) that can trigger contaminants like viruses and chemical pollution to degrade on the molecular stage. Finally, this response destroys the contaminants.
The bodily manifestation of this know-how is the brand new FRIRUS sprayer (first picture, picture credit score: Aving Information), which may generate and spray Plasma-activated water utilizing electrical energy and water as an enter. Created with the apparent environmental advantages above, the machine stays eco-friendly even after its lifecycle is over: most of it’s constituted of bio-degradable supplies. PALSOO is aiming for RE100.
Whereas decontamination by spraying has been highlighted throughout the pandemic, it’s used routinely in lots of nations. This plasma answer may even be used extra often, particularly in areas the place significantly susceptible folks (infants, aged, injured) might be uncovered to illnesses.
By activating a myst of water with Plasma, PALSOO creates an environment friendly method to decontaminate with out introducing dangerous chemical merchandise. The plasma sterilization impact will decay over time, however an fascinating side-effect of this course of is that the nitrogen-based components left have a fertilizer impact.
How lengthy does the Plasma impact final? PALSOO’s CEO says, “it varies relying on the temperature and kind of plasma. If in a gaseous state, the lifespan is longer however shortens when transformed to activated water. It lengthens at decrease temperatures and shortens at increased temperatures. Sometimes, plasma-activated water has a lifespan of about quarter-hour at 25 levels Celsius, ample to kill micro organism and is best because it disappears shortly, posing no hurt to people.”
This isn’t even taking into consideration that in occasions of disaster, a number of the chemical substances talked about above, decontaminant, could not even be out there, because it typically occurred throughout the pandemic. Clearly, utilizing water can even eradicate the price of shopping for and storing such chemical merchandise.
In a catastrophe scenario, the FRIRUS_24 might be deployed shortly, with out having to answer on the supply of any chemical substances. Electrical energy mills are often current and water is less complicated to seek out. PALSOO will current its sprayer, know-how and imaginative and prescient at CES 2025 in Las Vegas.
