PALSOO Plasma Sterilization: A Chemical-Free Resolution for Secure Decontamination

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 differ. Among the many listing of chemical substances incessantly sprayed are Bleach, Hydrogen peroxide, Alcohol, Peracetic Acid, or Chlorine Dioxide, for instance. Whereas they’ll obtain the aim of eliminating the contaminants, they’ll additionally trigger some stage of toxicity and environmental impression. Even the procurement and storage of those merchandise might be problematic.

PALSOO (all caps) is a Korean firm proposing a intelligent, non-toxic, and sustainable method to obtain the identical end result 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 system stays eco-friendly even after its lifecycle is over: most of it’s constructed from bio-degradable supplies. PALSOO is aiming for RE100.

Whereas decontamination by spraying has been highlighted in the course of the pandemic, it’s used routinely in lots of international locations. This plasma answer might even be used extra incessantly, particularly in areas the place notably susceptible individuals (infants, aged, injured) may very well 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, enough to kill micro organism and is best because it disappears shortly, posing no hurt to people.”

This isn’t even bearing in mind that in instances of disaster, among the chemical substances talked about above, decontaminant, might not even be out there, because it generally occurred in the course of the pandemic. Clearly, utilizing water can even remove the price of shopping for and storing such chemical merchandise. 

In a catastrophe scenario, the FRIRUS_24 may very well be deployed shortly, with out having to answer on the supply of any chemical substances. Electrical energy turbines are often current and water is less complicated to search out. PALSOO will current its sprayer, know-how and imaginative and prescient at CES 2025 in Las Vegas.
